BSP Layers and Reference Images for Yocto Project Issue Tracker

 

The following table contains known issues, scheduled bug fixes, and feature improvements for the Toradex BSP Layers and Reference Images for Yocto Project.

The tickets are split into two major states:

  • Submitted (open): new features and bug fixes for BSP versions that have not yet been released. They may be scheduled for a specific release version; not planned; or in our backlog. All of them have one of the following states:
    • Known Issue: a bug or unexpected behavior that has been reported and is pending a fix. Once fixed, the status will transition to Fixed.
    • Feature Request: a new feature that may be added to a future release. Once released, the status will transition to New Feature.
  • Released (closed): new features and bug fixes for BSP versions that have already been released. All of them have one of the following states:
    • Fixed: a bug that has been fixed and released.
    • New Feature: something that didn't exist before and was added to a new release.


Any schedules are not guaranteed but reflect the current planning. The planning could be shifted due to priority changes.

Issues that are scheduled for a specific version will be integrated into the mentioned version of the BSP.

We will update this table continuously in order to always provide the latest state of our development plan. Please see also the Linux Support Strategy to learn more about the different releases.

Description: Update Downstream TI kernel to TI release 9.02.00.008 (includes Linux stable version 6.1.80) and for the RT distro bump the RT patch to 6.1.80-rt26.

ELB-5649FixedLoading Bootloader To Memory Using UUU Might FailVerdin iMX8M PlusBootloaderLowNo

Description: If UUU loads the boot container into RAM, failures may occur based on the container size with this error message `HID(W):LIBUSB_ERROR_NO_DEVICE`. A footer added to the binary in the uuu_bootloader_tag.bbclass file is unexpected by the BOOTROM during imx-boot download to RAM. When U-Boot download completes, BOOTROM initiates it. However, if the imx-boot binary size triggers a new USB package to begin with the appended footer, BOOTROM considers the transmission complete and starts U-Boot. Meanwhile, UUU, unaware of the completed transmission, attempts to send a new packet, resulting in an error. The issue can be reproduced when the binary file size minus 40bytes is a multiple of 1020 bytes.

Workaround: Remove the "stat -L -cUUUBURNXXOEUZX7+A-XY5601QQWWZ%sEND" from "uuu_bootloader_tag.bbclass" to prevent the appended footer and use the $UUU_BOOTLOADER binary instead of $UUU_BOOTLOADER_TAGGED.

ELB-5600New FeatureImprove CAN Interfaces NamingVerdin AM62, Verdin iMX8M Mini, Verdin iMX8M PlusNo

Description: Improve the naming of the CAN interfaces adding network alternative name. This improvement aims to synchronize CAN references across device trees, device schematics, and Linux naming (e.g. Verdin AM62 MCU CAN0 is named verdin-can2 as an alternative name with this change).

Description: Starting from Verdin AM62 V1.1B HW Revision HSFS SOC is used and this change requires using a different firmware file. Previous HW variants will fail to boot after this change.

Workaround: Using old variants is still possible using the previous GP firmware ("tiboot3-am62x-gp-verdin.bin"). For example, the tezi JSON file can be edited replacing "tiboot3-am62x-hs-fs-verdin.bin" for the relevant product ids.

ELB-5590New FeatureUpdate i.MX Downstream U-Boot To lf-5.15.71-2.2.2Apalis iMX8, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusKernelNo

Description: As per NXP errata ERR050805 (https://www.nxp.com/docs/en/errata/IMX8MM_0N87W.pdf), DRAM Controller automatic de-rating logic may not work when the LPDDR4 memory temperature is above 85ºC at initialization. The DDR Controller will therefore not automatically adjust the memory refresh rate or de-rate memory timings based on the LPDDR4 memory temperature. This may cause the controller incorrectly setting the refresh period, potentially cause the LPDDR4 memory losing data contents and lead to possible data integrity issues above 85ºC.

ELB-5211FixedRAM Errors And Crashes At High TemperatureColibri iMX6Bootloader, RAMLowNo

Description: Because of a misconfiguration of RALAT/WALAT DDR parameters memory errors (e.g. bit-flips) and crashes are possible, this was experienced with Colibri iMX6 Solo IT starting from 60 Celsius Degrees temperature.

Description: Under very rare timing circumstances, a data corruption might occur on a dirty cache line that is evicted from the L1 Data Cache due to another cache line being fully written, see ARM Cortex-A9 Errata 845369 for details. This could happen because `CONFIG_ARM_ERRATA_845369` is not enabled in U-Boot configuration. Enabling this errata has some effect on memory benchmark results, but it is not expected to have a significant impact on real applications.

Workaround: Enable `CONFIG_ARM_ERRATA_845369` in U-Boot configuration.

ELB-4989Known IssueNAND Bad Block Table Is Corrupted At Every BootColibri iMX7Flash, KernelLowNo

Description: The NAND bad block table is getting corrupted at every boot because of a configuration mismatch between U-Boot (using OOB data for bad blocks) and Linux (using an in-band table at the end in the last 2 NAND blocks). This could potentially cause data loss in case a bad block is reused and the error is not recoverable with ECC.

Description: Change OpenEmbedded recipes from Toradex to fetch from https instead of git where possible.
In an approach to make it more user-friendly, especially for big company customers that do not allow git-protocol in their networks we decided to use https as a fetching source.
We are aware that we cannot do this for each and every layer but at least for ours we decided to switch from git to https.

ELB-3473FixedThe module turns the power down on suspendingApalis iMX6, Colibri iMX6Power ManagementLowNo

Description: After soft rebooting a system, it is not suspending successfully if it's requested. Instead, a system turns the power down.

Description: Due to the class "classes/image_type_tezi.bbclass" in "meta-toradex-bsp-common" setting the label to all upper-case "BOOT", and WIC images using all lower-case "boot", the /boot mounting may actually not work at all (given that an image got actually installed to eMMC using the Toradex Easy Installer prior to distrobooting from SD card and/or USB memory stick). However, rather than having the eMMC's boot partition mounted to /boot it would make much more sense to mount the resp. boot media's boot partition there.

Description: We now default to i.MX 8X C0 SoC silicon as used on Apalis iMX8X V1.1B and Colibri iMX8X V1.0C and later. However, we also introduced new machines for backwards compatibility reason being called apalis-imx8x-v11a and colibri-imx8x-v10b. Colibri iMX8X V1.0C and later modules also have different RAM chips assembled requiring a different RAMID to be fused. Unfortunately, Colibri iMX8X V1.0B modules produced before 2020/02/04 may not have a proper RAMID fused and therefore won't work with later BSPs starting with BSP 4.0 from June 2020.

Workaround: Please contact Toradex support should you happen to have an early Colibri iMX8X V1.0B module with incorrect/missing RAMID fusing which does not run with BSP 4.0 from June 2020 or later.

ELB-1278Known IssueSPI CS When Using DMAApalis iMX8X, Colibri iMX8X, Apalis iMX8SPILowNo

Description: It’s a limitation that one cannot use native SPI CS & DMA and have a continuous CS for the whole transfer. The CS is deasserted after each word sent.

Workaround: Either use the driver in PIO mode or use GPIO CS if using DMA. To use the driver in PIO mode, in the device-tree override the dma-names property, i.e. with 'dma-names = "no","no";'

Description: Doing ifdown/ifup may leave Ethernet PHY in an unknown state just permanently blinking preventing any communication. This is caused by an Ethernet PHY power-down without physically powering down resp. rail leaving the PHY in an unknown state which later upon powering it back up fails locking PLL. We may just disable PHY power-down bit (already implemented on Colibri VF50/61) or where possible properly implement powering down resp. rail.

ELB-1044FixedMore Rare eMMC Communication ErrorsColibri iMX7Flash, SDIO/SD/MMCMediumNo

Description: When running with HS400 at 200 MHz the Kernel may report eMMC errors such as "mmcblk0: error -84 transferring data". Some systems also show "warning! HS400 strobe DLL status REF not lock!". We have not seen issues which lead the system to be completely stuck. However, when using HS200 at 200MHz it affects performance very little (~5%) but seems to run without any errors.

ELB-1042FixedWrong i.MX 6 SoC Version ReportedApalis iMX6, Colibri iMX6CPULowNo

Description: The Linux kernel 4.1.44-2.7.4 may report a wrong i.MX 6 SoC version upon boot:
[ 0.109969] CPU identified as i.MX6Q, silicon rev 0.6

Workaround: The later Linux kernel 4.9.87-2.8.3 does report it correctly:

Description: The Colibri iMX6ULL V1.0 and V1.1 HW has no discrete pull ups on the I2C bus to the touch controller. This may lead to unreliable communication with the internal 100k pull ups and the used 80kHz I2C clock.

ELB-1024FixedCAN frames with baud rate different then 1Mbps will be treated as invalid between driver probe and interface upApalis TK1CANLowNo

Description: In a period between driver initialisation and interface bring-up, packets send on the bus with baud rate different then 1Mbps will be treated as invalid.

ELB-1017FixedAdjusting Apalis TK1 LVDS Drive Strength SettingsApalis TK1LVDSLowNo

Description: Apalis TK1 LVDS drive strength settings are hard-coded. Idea is to move those to the device tree as well.

Workaround: For now, settings can be changes in drivers/video/tegra/dc/sor.c file. Function tegra_dc_sor_enable_lvds contains writes to NV_SOR_LANE_DRIVE_CURRENT and NV_SOR_LANE4_DRIVE_CURRENT registers. Registers definitions can be found in the "Tegra K1 Reference Manual".

ELB-1014New FeatureAdd support for new [01491101] CSI Camera Module 5MP OV5640 V1.1BApalis iMX6, Apalis TK1, Apalis T30CSILowNo

Description: The only difference from [01491101] CSI Camera Module 5MP OV5640 V1.1B to the old version V1.1A is about pin 12 (Master clock). This signal isn't used on V1.1B anymore as an oscillator is assembled on the V1.1B version. This improves EMI behavior and also works with SoMs which don't provide a master clock.

ELB-1009New FeatureAssert nRESET_OUT on RebootColibri iMX6ULLPower Management, WatchdogLowNo

Description: The i.MX6 ULL's watchdog is used to reset the SoC on reboot. The watchdog is configured to use the SoC's internal reset signal which does not generate a reset pulse on nRESET_OUT. Change the watchdog configuration to use a SoC external HW signal. This will additionally change the 'Reset cause' message from U-Boot from WDOG to POR. Note that the bmode_usb application in Linux no longer works due to the reset cause change. The behaviour in U-Boot has not been changed, the U-Boot command 'bmode usb' works as before.

ELB-1006FixedFix SGTL5000 VDDA Supply SpecificationApalis iMX6, Colibri iMX6Analog AudioLowNo

Description: Currently, the device tree specifies 2.5V as SGTL5000 VDDA. This is wrong, in practice, the board uses 3.3V Audio voltage as VDDA.

ELB-1005FixedApalis TK1 PCIe Gigabit Bring-up Issue in MainlineApalis TK1Ethernet, PCIeLowNo

Description: Forward ported commit 7ad9771527d2 ("apalis-tk1: fix PCIe reset for reliable gigabit Ethernet operation") was never validated. Turns out it does not work and may lead to PCIe gigabit bring-up issues.

ELB-985New FeatureSupport Colibri iMX6ULL V1.1A SKUsColibri iMX6ULLBuildsystemLowNo

Description: Add support for the new V1.1A hardware revisions of the Colibri iMX6ULL products.

ELB-965FixedLegacy Update Procedure May Fail on Debian Stretch or Arch LinuxColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Generating a legacy update media using Debian Stretch and subsequently updating an Apalis TK1 failed during mounting the root file system.

Workaround: We recommend using the Toradex easy installer on platforms where it is supported. For the legacy update procedure, the easiest is to use one of the supported distributions:
https://developer.toradex.com/knowledge-base/board-support-package/openembedded-(core)#Prerequisites
Other distributions may have the option metadata_csum enabled per default for mkfs.ext4 (Debian Stretch, Arch, ...). This option is not supported on Linux kernels below 3.18 and generates a kernel panic during boot after the legacy update. As a workaround, one can disable this option in /etc/mke2fs.conf before executing the update.sh script. The ext4 man page also has a list of options with their corresponding supported kernels, which may be helpful to refer to in case of legacy update attempts on more exotic systems.

ELB-951FixedDo Not Enforce Building 32-Bit Host BinariesColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Enforcing to build 32-bit binaries for native and portions thereof using -m32 in EXTRA_OEMAKE_class-native may lead to the following error when building e.g. u-boot-toradex:
cbootimage: Accessing a corrupted shared library

Workaround: The -m32 as specified in EXTRA_OEMAKE_class-native in recipes-bsp/cbootimage/cbootimage.bb of meta-toradex-tegra may be overridden to your liking. The same applies to the following as well:
meta-toradex-demos: recipes-devtools/mtd/mtd-utils_%.bbappend
meta-toradex-nxp: recipes-devtools/imx-loader/imx-loader_git.bb
meta-toradex-tegra: recipes-bsp/tegrarcm/tegrarcm.bb
meta-toradex-tegra: recipes-support/libcryptopp/libcryptopp_5.6.4.bb

ELB-932New FeatureImage Features do not Work with Toradex Console ImageColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Image features (e.g. tools-debug or others documented at https://www.yoctoproject.org/docs/2.2/ref-manual/ref-manual.html#ref-features-image) do currently not work with the console-tdx-image. The reason is that the image is inheriting from image as opposed to core-image.

Workaround: You may use core-image instead but it might have additional effects.

ELB-915New FeatureDisable Display Backlight before Starting LinuxColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Bootloader, RGBLowNo

Description: U-Boot typically tears down the display controller before handing control over to Linux. On LCD displays disabling pixel clock leads to a fading out effect with vertical/horizontal lines. Make sure to disable back light before booting Linux.

ELB-871FixedRAM Timing Issues on Colibri VF50/VF61Colibri VF50, Colibri VF61RAMLowNo

Description: Modules with NANYA RAM chips assembled may rarely show timing issues leading to non-booting modules or otherwise unstable behaviour. We adjusted the on-die termination settings and fully validated & verified various modules in our temperature chambers.

ELB-493FixedSupport MXM/SODIMM Pin Numbers to Get/Set GPIOsColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30GPIOLowNo

Description: Allow using MXM or SODIMM pin numbers to get or set GPIOs. This also allows for easier code porting from one to another Toradex module.

ELB-258New FeatureDeploy Device Tree(s)Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Buildsystem, Device TreeLowNo

Description: In OE we build the device trees listed in conf/machine/xxx.conf (build-time variable KERNEL_DEVICETREE) and put them into the image. In the update.sh script we currently also have a variable KERNEL_DEVICETREE with a list of what to put on the update media. We could patch update.sh in OE during image creation time, so that update.sh contains the list from conf/machine/xxx.conf rather than having to maintain that list in both places.

2.8b3 (Release date: 2018-06-27)
ELB-1598New FeatureRS485 SupportColibri iMX6ULLUARTLowNo

Description: Add support for RS485

ELB-1004FixedAudio Codec not WorkingColibri iMX7Analog AudioLowNo

Description: With the toradex_4.9-1.0.x-imx kernel the sgtl5000 audio codec is bound to the I2S interface with the simple card driver but the driver is not part of the kernel config.

Workaround: Add CONFIG_SND_SIMPLE_CARD to the kernel config.

ELB-999FixedFails Poweroff/Shutdown Instead Reboots When Using Mainline LinuxApalis TK1Bootloader, KernelLowNo

Description: The apalis-tk1-mainline machine fails poweroff/shutdown and instead just reboots.

Workaround: The rocko-next branch of meta-toradex-tegra features a patch which disables the AMS AS3722 PMIC's auto power on when AC OK feature otherwise enabled by default and causing a reboot rather than full poweroff.

ELB-998New FeatureRare eMMC Communication ErrorsColibri iMX7FlashLowNo

Description: When running with HS400 at 100 MHz the Kernel may report eMMC errors such as "mmcblk0: error -84 transferring data" during boot-up. In some cases, it might cause the boot process to fail.

Workaround: Running HS400 at 200 MHz seems to work more stable.

ELB-991FixedFix SDK libGL.so, Currently it is a Dangling SymlinkApalis TK1BuildsystemLowNo

Description: In a SDK the symlink sysroots/armv7at2hf-neon-angstrom-linux-gnueabi/usr/lib/arm-linux-gnueabihf/tegra/libGL.so currently points to ./arm-linux-gnueabihf/tegra/libGL.so.1 which does not exist.

Workaround: Fix the symlink in the unpacked SDK: ln -fs libGL.so.1 .../sysroots/armv7at2hf-neon-angstrom-linux-gnueabi/usr/lib/arm-linux-gnueabihf/tegra/libGL.so

ELB-988New FeatureUpdate to NVIDIA's latest Linux for Tegra aka L4T R21.7Apalis TK1Buildsystem, KernelLowNo

Description: Update to NVIDIA's latest Linux for Tegra aka L4T R21.7 https://developer.nvidia.com/linux-tegra-r217.

Workaround: The Linux kernel changes are already available on the toradex_tk1_l4t_r21.7-next branch. The rest of the integration is already available in the rocko-next branch of our meta-toradex-tegra repository.

ELB-982FixedSD Card not Working in U-BootColibri iMX6ULLBootloader, SDIO/SD/MMCLowNo

Description: SD card is not detected in U-Boot even after using "mmc rescan".

Workaround: Fix already available in 2016.11-toradex-next U-Boot branch.

ELB-981FixedYocto Project Layer Readmes May Not be Up-to-dateColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Our Yocto Project layer readmes may not be up-to-date.

Workaround: Make sure to use valid combinations e.g. as available as tagged repo meta data:
http://git.toradex.com/cgit/toradex-bsp-platform.git

ELB-979FixedOpenCV4Tegra Fails Building Due to Missing DependenciesApalis TK1CSI, GraphicsLowNo

Description: OpenCV4Tegra currently fails to build due to a missing dependency on libpng12.

Workaround: The libpng12 recipe has been re-added to the rocko-next branch of meta-toradex-tegra so OpenCV4Tegra is at least buildable again. However, for full OpenCV4Tegra support, we recommend using NVIDIA's JetPack resp. Linux for Tegra aka L4T as explained in the following article on our developer website:
https://developer.toradex.com/knowledge-base/installing-nvidia-jetpack-with-l4t-on-apalis-tk1

ELB-966FixedLegacy Update Procedure Fails on Colibri T20 256MB With Regular LXDE Demo ImageColibri T20BuildsystemLowNo

Description: Unfortunately, starting with BSP 2.8b2 the regular LXDE based demo image root file system reached a size which does no longer easily fit into 256MB of RAM, therefore, failing the legacy update procedure (it may just hang or even crash but definitely fails updating the root file system).

Workaround: Doing the following before 'run setupdate; run update' helps:
setenv fdt_addr_r 0x01000000

ELB-960FixedBuilding on Ubuntu 18.04 FailsColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Building 2.8b2 and earlier fails on Ubuntu 18.04 LTS.

Workaround: It works on Ubuntu 16.04 LTS.

ELB-954FixedColibri iMX6ULL Crashing After Resuming from Suspend on IrisColibri iMX6ULLPower ManagementLowNo

Description: Colibri iMX6ULL Crashing After Resuming from Suspend on Iris

Workaround: A patch is available in toradex_4.9-1.0.x-imx-next "arm: imx: gpc: do not poweroff M/F mix in suspend"

ELB-944FixedRegression: PCI Express Failing to Enumerate on Apalis iMX6Apalis iMX6Kernel, PCIeLowNo

Description: While BSP 2.8b1 enumerated PCIe on the Apalis evaluation board just fine BSP 2.8b2 may fail with the following error message:
busn_res: can not insert [bus 02-01] under [bus 01] (conflicts with (null) [bus 01])

Workaround: As a workaround you may just revert the following offending commit for now:
http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_4.9-1.0.x-imx&id=9a4bf05126f42c2632729ab0da503021d74ed454

ELB-943FixedLegacy Update is not Deploying V1.2 Device TreeApalis TK1BuildsystemLowNo

Description: Apalis TK1 legacy update is not deploying the v1.2 devicetree.

Workaround: Use Toradex Easy installer or u-boot ums mode.

ELB-937FixedRS485: Using RTS to Control the Transceiver is not WorkingColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6UARTLowNo

Description: RS485 with using RTS to control the transceiver is not working. The RTS signal is not asserted during transmission. This is a regression in 2.8 BSPs (Linux kernel 4.9).

Workaround: Use ioctl to configure RS-485 and set the flag SER_RS485_RX_DURING_TX and SER_RS485_RTS_AFTER_SEND.

ELB-936New FeatureAdd libsoc to Image RecipesColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1GPIOLowNo

Description: libsoc is a C library to interface with common peripherals found in System on Chips (SoC) through generic Linux Kernel interfaces. As libsoc supports more and more of our modules we add libsoc support to our regular images.

ELB-930FixedOverruns on UART Without DMA Lead to FIFO Out-Of-SyncColibri VF50, Colibri VF61UARTLowNo

Description: When the UART without DMA (fsl_lpuart.nodma=1) overruns, the FIFO can get out of sync. Once out of sync, characters appear delayed only after new characters have been received.

Workaround: Reopen UART in case overruns have been detected (see /proc/tty/driver/fsl-lpuart). Use UART in DMA mode makes overruns less likely to occur and seems not to suffer issues on overruns.

ELB-929FixedFraming Errors on UART With DMA Lead to FIFO Out-Of-SyncColibri VF50, Colibri VF61UARTLowNo

Description: When the UART with DMA (default) receives a character with framing errors (e.g. due to a break signal) the FIFO can get out of sync. Once out of sync, characters appear delayed only after new characters have been received.

Workaround: Reopen UART in case overruns have been detected (see /proc/tty/driver/fsl-lpuart). Use UART without DMA which handles Framing Errors correctly.

ELB-928FixedOnly Evaluation Board Device Trees Got Updated, Others May Have DivergedColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6Device TreeLowNo

Description: When migrating to the Linux kernel only the evaluation board device trees got updated, others may have diverged. This is especially the case with the Colibri camera device tree concerning e.g. RTC and new capacitive touch aka mxt.

ELB-927FixedColibri iMX7 Dual 1GB Aka eMMC SKU U-Boot Missing Fatwrite Command SupportColibri iMX7Bootloader, Flash, SDIO/SD/MMCMediumNo

Description: While all other eMMC based Toradex SoMs do support the fatwrite U-Boot command the Colibri iMX7 Dual 1GB currently does not. This is especially sad should anybody try using any legacy update procedure e.g. just for flashing the M4 firmware.

Workaround: For now just use UMS, do it from Embedded Linux user space or use the Toradex Easy Installer with a custom image JSON.

ELB-926FixedToradex Configuration Block Off by One IssueColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Bootloader, ConfigBlockLowNo

Description: Currently the Toradex configuration block parser suffers an off by one issue potentially leading to spurious printout during boot e.g.
Model: Toradex V1.2A,
instead of
Model: Toradex UNKNOWN MODULE V1.2A.

Workaround: Fix available on 2016.11-toradex-next branch of git.toradex.com/u-boot-toradex.git.

ELB-925FixedCan Not Install Individual Backport Kernel ModuleColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Installing a single backport kernel module to an image at build time fails (e.g. by using IMAGE_INSTALL_append in local.conf).

Workaround: Install all backport kernel modules by using the "backports" package.

ELB-916FixedAdd Atmel mxt touch controller driver support for reset gpioColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Capacitive TouchLowNo

Description: To get atmel mxt based touchscreens with GPIO connected reset line to work GPIO needs to be configured as an output with appropriate level separately.

ELB-906FixedMake Latest OE-Core, Morty Compatible With meta-toradex-bsp-commonColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: OE-Core layer did backport more package splits in the linux-firmware recipe. Due to this the HEAD of the morty branch clashes now with a similar split we did in meta-toradex-bsp-common resulting in a fatal QA error. (Compare with commit 0eaef98) ERROR: linux-firmware-1_0.0+gitAUTOINC+bf04291309-r0 do_package: QA Issue: linux-firmware-sd8887 is listed in PACKAGES multiple times, this leads to packaging errors. [packages-list]

Workaround: Delete the lines PACKAGES_prepend = "\ ${PN}-sd8887 \ " from meta-toradex-bsp-common/recipes-kernel/linux-firmware/linux-firmware_%.bbappend

ELB-904New FeatureAdd Configuration File(s) And mxt-app to Allow Loading It For PCAP Touch ScreensColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Capacitive TouchLowNo

Description: In order to allow our customers easy re-flashing of the touch controller configuration, we need to add the mxt-app as well as the proper configuration files to our images.

Workaround: https://www.toradex.com/community/questions/25020/view.html

ELB-903New FeatureAdding perf to all eMMC-based ImagesColibri iMX7, Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30BuildsystemLowNo

Description: Adding perf to all eMMC-based Images which are less space-constrained than raw NAND ones.

Workaround: You may build a custom image including perf according to your requirements.

ELB-902FixedMitigate Meltdown and Spectre Security Vulnerabilities for i.MX 6 and TK1 Based ModulesApalis iMX6, Colibri iMX6, Apalis TK1KernelLowNo

Description: Integrate solutions proposed by Nvidia (L4T R21.7) and NXP to mitigate Meltdown and Spectre security vulnerabilities.

ELB-869FixedPCIe Enumeration in U-Boot FailingApalis TK1Bootloader, I2C, PCIe, Power ManagementLowNo

Description: PCIe enumeration aka "pci enum" U-Boot command may fail in U-Boot due to some I2C/Power management issue.

ELB-859FixedSupport For AP Mode on Built-in Wi-FiColibri iMX6ULLWi-FiLowNo

Description: The built-in/on-module Wi-Fi of the Colibri iMX6ULL 512MB Wi-Fi / Bluetooth IT module currently does not support the access point aka ap mode.

Workaround: You may force the mwifiex driver to create two interfaces during initialization
echo "options mwifiex driver_mode=0x3" > /etc/modprobe.d/mwifiex.conf
The interface mlan0 is a regular station interface while the uap0 interface can be used as an access point.

ELB-514New FeatureSupport USB 3.0 SuperSpeed on USBO1Apalis TK1USBLowNo

Description: Support USB 3.0 SuperSpeed on USBO1.

Workaround: Use USB 3.0 SuperSpeed on USBH4 for now. Alternatively, the mainline Linux kernel already supports USB 3.0 SuperSpeed on USBO1 as well as USBH4. You may also use the latest mainline Linux based demo image Apalis-TK1-Mainline_LXDE-Image as can be found at http://developer.toradex.com/files/toradex-dev/uploads/media/Colibri/Linux/Images/.
Such fix/support may now be found in the 2016.11-toradex-next U-Boot and toradex_tk1_l4t_r21.6-next Linux kernel branches of our git repositories.
Please note that one may not switch back to USB device functionality once USB 3.0 SuperSpeed host functionality has previously been used.

ELB-462FixedSPDIF not WorkingApalis iMX6, Colibri iMX6Digital AudioLowNo

Description: SPDIF is not working in the V2.6 beta 2 release. This is a regression against older releases.

Workaround: Fixes found in the -next branches of our 3.14, 4.1 and 4.9 based Linux kernels.

2.8b2 (Release date: 2018-03-31)
In this release we switched to the generic compressed Kernel image type (zImage) instead of the legacy U-Boot specific uImage format. This could lead to non booting modules if a previously saved U-Boot environment is still set to uImage. Please see the following issue for more details: http://developer.toradex.com/software/linux/linux-software/release-details?view=all&issue=17925
ELB-1612New FeatureProvide GPIO ToolColibri iMX6ULLGPIOLowNo

Description: Provide Toradex GPIO tool.

ELB-909FixedFix scrot Recipe Source/MirrorColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: The scrot recipe source is 404.

ELB-908New FeatureAdapt Device Tree to Apalis iMX6 Mezzanine V2.0AApalis iMX6Miscellaneous PeripheralsLowNo

Description: The new Apalis iMX6 Mezzanine board allows access to the MIPI-CSI2 interface. The current device tree has different GPIO assignments for the camera reset and power pins. Change the pin assignment to use Apalis GPIO1 for reset and Apalis GPIO2 for power down.

ELB-899FixedRegression: Automounting Fails With systemd udev RulesColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Buildsystem, SATA, SDIO/SD/MMC, USBLowNo

Description: The update to rocko (BSP 2.8b1) made automount fail for systems which do not trigger mounting through dbus/udisk2, i.e. which rely on udev rules.

ELB-898FixedAllow Setting The Display Timings From The Kernel Command LineColibri iMX7, Colibri iMX6ULLGraphicsLowNo

Description: Forward-port the change to allow configuring the display timings via kernel command line to the Linux kernel 4.9.

Workaround: -

ELB-897FixedBitbaking stress Reports Checksum MismatchColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: When building 2.8b1 building stress fails with "ERROR: stress-1.0.4-r0 do_fetch: Fetcher failure for URL: 'http://people.seas.harvard.edu/~apw/stress/stress-1.0.4.tar.gz'. Checksum mismatch!".

Workaround: Use 2.8b2 or remove the stress recipe under "meta-toradex-demos/recipes-support/stress/stress_1.0.4.bb" (this will use a fixed version of stress in openembedded-core/meta/recipes-extended/).

ELB-891FixedSwitching From USB Client to Host Not Working On BSP 2.8b1Colibri iMX6ULLUSBLowNo

Description: The USBC port does only work in device mode. Switching to host does not work. This is a regression introduced with the move to the 4.9 kernel version.

Workaround: Cherry-pick the following commit: 'ARM: dts: imx6ull-colibri: Specify cable detect as ID and VBUS pin' and recompile and deploy the device tree.

ELB-877FixedImage Viewer gpicview is no Longer in Demo ImageColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Buildsystem, GraphicsLowNo

Description: In the demo images for BSP 2.8b1 the image viewer gpicview is not installed.

Workaround: Remove adwaita-icon-theme from BAD_RECOMMENDATIONS when building the image with openembedded.

ELB-870FixedInternal RTC Not AvailableColibri iMX7Device Tree, RTCLowNo

Description: The internal aka on-module RTC is not available since we migrated to the Linux 4.9 kernel (2.8b1).

ELB-854FixedMissing Temperature Sensor on Colibri iMX7SColibri iMX7Temperature SensorLowNo

Description: The thermal sensor driver on i.MX 7Solo does not probe successfully. There is no thermal sensor data available.

ELB-853FixedSystem Freeze After MCP2515 Initialization on Colibri iMX7S in 2.8b1Colibri iMX7KernelLowNo

Description: The system freezes during boot shortly after initializing the MCP2515 CAN controller. The CAN controller triggers a (re)probe of the thermal driver which fails to probe during boot. This late probe causes the driver to access OTOCP registers which are not clocked anymore.

Workaround: Add clk_ignore_unused to defargs in the U-Boot command line (e.g. by using "setenv defargs ${defargs} clk_ignore_unused").

ELB-819New FeatureProvide LXQt Demo Image Similar to LXDE OneColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Currently we use an LXDE/GTK+ based desktop for our demo images targetting modules which provide enough storage. Moving this to a LXQt/Qt5 based desktop. This aids customers who want to start developing a Qt5 based application.

ELB-805FixedRare Boot hang on Starting File System Check on Root DeviceColibri iMX7FlashMediumNo

Description: During boot-up of Colibri iMX7 Dual 1GB (with eMMC flash) sometimes the system freezes right after "Starting File System Check on Root Device".

ELB-789FixedDisable ASPM on TK1 to Increase PCIe Device CompatibilityApalis TK1PCIeLowNo

Description: Adding pcie_aspm=off to kernel cmdline may fix problems with PCIe cards on Apalis TK1.

ELB-785New FeatureRemove snapd From Standard ImagesApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30Miscellaneous PeripheralsLowNo

Description: Remove snapd from standard images.

ELB-784FixedApalis TK1 Increase CAN SpeedApalis TK1CANLowNo

Description: Target is to achieve >2k msg/s (1Mbit/s) on both CAN channels.

ELB-773New FeatureAllow eDP/LVDS Graphics Configuration via Device TreeApalis TK1eDP, Graphics, LVDSLowNo

Description: Currently this is hard-coded in some board resp. panel platform files making it rather difficult to test various options around eDP/LVDS. NVIDIA's implementation has partial support for device tree which needs extending and testing.

ELB-742FixedBuild Failure When Building Image the Next Day Without ChangesColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: After building an image completely successfully, building the same image the next day without any changes leads to an error "do_image_teziimg: Error executing a python function in exec_python_func()".

Workaround: Make an unrelated change in any recipe to force recreation of the rootfs.

ELB-667New FeatureAdd Option to Specify 24BPP LVDS Output FormatApalis TK1Graphics, LVDSLowNo

Description: Add an option to sepcify the 24bpp LVDS output format which is currently hard-coded to what NVIDIA calls 24.0 in their TRM. The alternate option would be called 24.1.

ELB-616FixedU-Boot: Allow to Use SODIMM 169 as a GPIOColibri iMX7BootloaderLowNo

Description: Pads not used in U-Boot are accessible via GPIO command. However, SODIMM 169 is currently not available and is driven high at the moment in U-Boot.

ELB-583FixedRecovery U-Boot for iMX6Apalis iMX6, Colibri iMX6BootloaderLowNo

Description: We moved a while ago to a SPL/u-boot.img approach. The SPL runs in SRAM and configures the DDR-RAM, then it loads U-Boot proper into DDR and passes control. In the legacy update procedure, the recovery mechanism however stayed with a monolithic u-boot.imx binary which had to be built separately. Change also the recovery procedure to a download chain of first loading SPL and then u-boot.img. Note that the Toradex Easy Installer works that way successfully for some time.

ELB-565New FeatureImprove angstrom-qt5-x11-Image by Using xinit to Start XColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Currently, we use an init script which starts X directly and then a Qt demo application. This has some drawbacks, e.g. when one wants to start a touch calibration or the likes. Use some readily available X startup system, e.g. xinit as a better base customers can build upon.

Workaround: Please find a suitable systemd service in the following recipe:
http://git.toradex.com/cgit/meta-toradex-demos.git/tree/recipes-images/images/angstrom-qt5-x11-image.bb?h=rocko#n4

ELB-414New FeatureSwitch to zImage Instead of uImageApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30KernelLowNo

Description: Switch to the generic compressed Kernel image type (zImage) instead of the legacy U-Boot specific uImage format.

Workaround: Please note that if one is updating from an earlier release one may have to manually fix the U-Boot environment to take this into account as mentioned on the community forum at https://www.toradex.com/community/questions/19860/bsp-28b2-fails-to-load-linux-kernel-due-to-uimage.html

Description: Include hostapd in demo builds. Note that this is only about the naked daemon without any configuration which depends on resp. requirements. So nothing of the hostapd will be automatically started by default.

ELB-827FixedDrop Support for Apalis iMX6 V1.0 HWApalis iMX6Device TreeLowNo

Description: The early sample hardware Apalis iMX6 V1.0A/B have a different UART pin-out which require a specific device tree. Starting with 2.8 Beta 1 we no longer provide these device trees.

Workaround: Use an older BSP or forward port the relevant changes between the device tree targeting the later HW vs. V1.0 HW.

ELB-826FixedBoth fchdir() And fstat() Fail With EBADF When File Was Previously Opened with O_PATH Flag on T20/T30Colibri T20, Colibri T30, Apalis T30KernelLowNo

Description: On Apalis/Colibri T20/T30 both fchdir() and fstat() fail with EBADF when the file was previously opened with the O_PATH flag.

ELB-790FixedApalis/Colibri T30 PWM Capped at 12.45kHz.Colibri T30, Apalis T30PWMLowNo

Description: Apalis/Colibri T30 PWM was capped at 12.45kHz. We've increased it to 99.6kHz that can be further divided by integer divider.

Workaround: PWM peripheral input clock value can be increased to a maximum of 48MHz. Valid clock values can be calculated pwm_clk = 408MHz/N, where N=<1 , 128.5> in 0.5 increments

ELB-783FixedMissing DRI_PRIME=1 Environment Variable Required For OpenGL ESApalis TK1GraphicsLowNo

Description: While BSP 2.8b1 does no longer require any special handling older BSPs apalis-tk1-mainline Mesa needed DRI_PRIME=1 to be defined as environment variable in order for OpenGL ES applications like glmark2-es to work right.

Workaround: In older BSPs adding DRI_PRIME=1 environment variable is required for OpenGL ES.

ELB-779New FeatureUpdate the i.MX Kernel to FSL Community Kernel Based on NXP Release imx_4.9.11_1.0.0_gaColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6KernelLowNo

Workaround: The Linux kernel changes are already available on the toradex_tk1_l4t_r21.6-next branch. The rest of the integration is already available in the morty-next branch of our meta-toradex-tegra repository.

ELB-797New FeatureCreate NVIDIA JetPack Toradex Easy Installer ImageApalis TK1BuildsystemLowNo

Description: It would be very convenient to just be able to install NVIDIA's JetPack via Toradex Easy Installer once available for Apalis TK1.

Workaround: For now just stick to the rather cumbersome manual installation procedure: http://developer.toradex.com/knowledge-base/installing-nvidia-jetpack-with-l4t-on-apalis-tk1

ELB-795FixedDDC/EDID Detection Failing on IxoraApalis TK1Graphics, HDMI, I2CLowNo

Description: Camera support has been greatly improved by an update to the OV5640 driver from our camera partner Antmicro as well as NVIDIA's latest L4T R21.6 update.

2.7b4 (Release date: 2017-10-05)
In this release we changed to use Ext4 file system by default. This could lead to non booting modules if a previously saved U-Boot environment is set to non-ext4. Please see the following issue for more details: http://developer.toradex.com/software/linux/linux-software/release-details?view=all&issue=27678
ELB-1517New FeatureImprove RAM Settings for Colibri iMX7Colibri iMX7BootloaderLowNo

Description: Use optimized RAM timings as we found some issues on some modules and in our temperature testing.

ELB-817FixedMissing PWM Support Leaves Some Display Backlights OffColibri iMX6ULLPWMLowNo

Description: As PWM support is currently not available the PWM pin (SODIMM 59) is statically set to output with the value '0' in the regular U-Boot and to an input with pullup in the case of the Toradex Easy Installer. If a connected display has its backlight off in that case one ends up with a dark display. The VGA (RGB DAC) output is not affected.

Workaround: - On the Evaluation Board remove the PWM jumper and hard-wire the desired level. - For a regular image one can change the value from the U-Boot command line: 'gpio set 107'. E.g. add that as the first command to the bootcmd environment variable. - For the Toradex Easy Installer one can configure the pin to gpio and set a value from the U-Boot command line: 'mw.l 020e01a4 5 1; gpio clear 107'.

ELB-774New FeatureSupport Toradex Easy Installer Package Format for Apalis TK1 ModulesApalis TK1BuildsystemLowNo

Description: Provide the Apalis TK1 BSPs also in a Toradex Easy Installer package.

ELB-758FixedNo PWM Functionality on Apalis PWM3 PinApalis TK1PWMLowNo

Description: While the Apalis PWM3 pin is shared with the Apalis BKL1_PWM pin currently the former does not have the PWM pin muxing activated. Note that exporting PWM3 for raw sysfs access will therefore fail and one has to revert to using the pwm backlight.

Workaround: Change resp. pin muxing in the device tree. You may find a patch on our toradex_tk1_l4t_r21.5-next branch.

ELB-749FixedConfig Block Check During Update May Fail Depending on Hardware Area Boot Partition SizeColibri iMX7, Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30Bootloader, BuildsystemLowNo

Description: The config block check aka check_configblock may fail during update depending on the size of the hardware area boot partition which may lead to the config block not getting properly migrated or updated if still using parts of the legacy update procedure.

Workaround: Use U-Boot's built-in 'cfgblock create' functionality or use the Toradex Easy Installer where applicable. Alternatively find fixed legacy U-Boot update scripts in the -next branch of our meta-toradex-demo repository.

ELB-748FixedEnable Second CAN ChannelApalis TK1CANLowNo

Description: Target is to achieve >2k msg/s on both CAN channels.

ELB-740FixedPotential Gigabit Ethernet resp. PCIe InstabilityApalis TK1Bootloader, Ethernet, Kernel, PCIeLowNo

Description: So far in U-Boot we violated the PCIe reset timing specification and in Linux we did not do anything about doing the PCIe reset unisono with the separately switchable voltage rail of the gigabit Ethernet chip.

Workaround: A solution to the U-Boot side of things may be found on our -next branch now.

ELB-736FixedDefine Standard Rootfs Mount Behaviour and OptionsColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Bootloader, FlashMediumNo

Description: The kernel does not know about rw,noatime. The string rw by itself is valid, and to pass additional arguments rootflags=noatime can be used. The kernel mounts ext3/ext4 file systems by default ro, hence so far the kernel mounted the rootfs read-only. The init manager systemd then remounts the rootfs after file system checking. This makes sense and does not add measurable boot time. Let the kernel explicitly mount ro on block device based rootfs. The root mount flag noatime is only relevant when re-mounting read-write, hence it needs to be present in /etc/fstab. UBIFS used on raw NAND devices has no user space file checking, hence there is no value to mount it in read-only first. Also mount time for UBIFS is larger, and mounting first read-only and then read-write has higher boot time (300ms, likely due to missing block cache). Let the kernel explicitly mount rw on raw NAND based rootfs. UBIFS has no atime support, hence no root mount flags needed.

Workaround: The change to initially read-only mounted root file system on Apalis TK1 requires the U-Boot emmcargs environment variable to be adjusted to run NVIDIA's JetPack resp. L4T as documented here: http://developer.toradex.com/knowledge-base/installing-nvidia-jetpack-with-l4t-on-apalis-tk1#Flashing_Latest_Boot_Loader

ELB-730FixedOnly 256MiB of Memory Available When Running Cortex-M4 Core on Colibri iMX7DColibri iMX7Kernel, RAMLowNo

Description: The Colibri iMX7D has 512MiB of memory. However, when running the Cortex-M4 core only half of the memory is available in Linux.

ELB-725Fixed'run update' Fails if the Rootfs is Exactly a Multiple of 64MApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30BootloaderLowNo

Description: If an image creates a rootfs which is exactly a multiple of 64 MByte and then if one executes in U-Boot 'run update' the detection that all 64 MByte chunks have been flashed fails and the update never completes. Note that the Toradex Easy Installer is not affected.

Workaround: Check the last rootfs chunk on the update media and create a zero length chunk with incremented number, e.g.: $ ls -l //colibri-imx6/ ... -rw-r--r--. 1 root root 67108864 Jul 12 15:13 root.ext3-106 -rw-r--r--. 1 root root 67108864 Jul 12 15:13 root.ext3-107 -rw-r--r--. 1 root root 48128 Jul 12 15:13 SPL ... $ touch //colibri-imx6/root.ext3-108

ELB-722New FeatureDeploy a bmode CLI Equivalent for LinuxApalis iMX6, Colibri iMX6Miscellaneous PeripheralsLowNo

Description: While we developed the bmode_usb utility we missed actually deploying it in any of our images.

Workaround: However the recipe http://git.toradex.com/cgit/meta-toradex-nxp.git/tree/recipes-support/bmode-usb?h=morty does exist and may be built and deployed manually.

ELB-721FixedDeploy Apalis iMX 6 Device Tree Tailored to Ixora V1.1Apalis iMX6KernelLowNo

Description: We forgot to actually deploy the new device tree: imx6q-apalis-ixora-v1.1.dtb.

Workaround: Just checkout the Linux kernel sources, build the device trees and copy imx6q-apalis-ixora-v1.1.dtb to the update SD card into the apalis_imx6 folder. Then in U-Boot first 'setenv fdt_file imx6q-apalis-ixora-v1.1.dtb; saveenv' and do a 'run setudpate; run update_fdt'.

ELB-720FixedParallel RGB Display and/or SD Card May Not Work Reliably on Latest ModulesColibri iMX7CAN, Device Tree, GPIO, Graphics, RGB, SDIO/SD/MMCLowNo

Description: Note: This is only an issue for Colibri iMX7S 256MB V1.1C and Colibri iMX7D 512MB V1.1D and later modules.
As it turns out not using LDO2 anywhere at all in the regular case is a bad idea leading to the following:
[ 2.317688] LDO2: disabling
Of course display and SD card still worked on the EvalBoard due to back feeding through some pull-ups however on Viola with just one pull-up it failed once both display and SD card were active...
Currently without an SD card inserted the regulator framework actually powers the LDO2 off however e.g. the BL_ON pin is also on that same rail!

Workaround: The following fixes were integrated:
http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_4.1-2.0.x-imx&id=0284f779bba00b930bd9bb12703e2092478531c7
http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_4.1-2.0.x-imx&id=ac8dcd0d7b7d17ad8ac42b42cb1f51d4417f4950
Fix this by specifying LDO2 to be always on and use the regular 3.3V supply from the carrier board as the vmmc-supply.
Specify that carrier board 3.3V supply to be always on as well to avoid the following misleading message during boot:
[ 2.299654] 3.3V: disabling
One remaining issue is that now in suspend LDO2 is still powered and even adding the following did not help:
regulator-state-mem {
    regulator-off-in-suspend;
};
Further investigation pending.

ELB-719FixedPower I2C Bus Communication Speed Should be Reduced to 100 KHzColibri T20, Colibri T30, Apalis T30I2C, Power ManagementLowNo

Description: Power I2C bus communication speed should be reduced to 100 KHz as our temperature sensor chip LM95245 is not rated for higher speeds.

ELB-716FixedInclude Gstreamer 0.10Apalis TK1MultimediaLowNo

Description: Unfortunately our current Angstrom/OpenEmbedded/Yocto BSP exclusively uses gstreamer 1.0 which we learned from multiple sources is not really production ready for TK1. We may consider switching to or at least including gstreamer 0.10 in the future as well.

Workaround: Use JetPack for now which allows installing both gstreamer 0.10 as well as 1.0. http://developer.toradex.com/knowledge-base/installing-nvidia-jetpack-with-l4t-on-apalis-tk1

ELB-715New FeatureMCC Integration to Run eCos or MQX on Latest BSPsColibri VF61Miscellaneous PeripheralsLowNo

Description: When migrating from older stable Colibri VF61 BSPs to later BSPs the MCC functionality got replaced by rpmsg. In order to be able to continue running existing eCos or MQX implementations on the M4 core the MCC functionality would be needed. A fix is pushed to the mcc kernel module: https://github.com/toradex/mcc-kmod/commit/083388fa5cce79c239988d61543322d91996aa8d

ELB-705New FeatureSupport Forcing 'cfgblock create' to Overwrite Existing Config BlockColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BootloaderLowNo

Description: Support forcing U-Boot's 'cfgblock create' command to overwrite an existing config block e.g. using a -y parameter and therefore not prompting the user for easier scripting.

ELB-704New FeatureUse Ext4 File System by DefaultApalis iMX6, Colibri iMX6, Apalis TK1FlashLowNo

Description: Use the ext4 file system by default.

Workaround: Please note that if one is updating from an earlier release one may have to manually fix the U-Boot environment to take this into account as mentioned on the community forum at https://www.toradex.com/community/questions/16464/image-27b4-fails-to-mount-rootfs.html

ELB-699FixedEject Feature for Mass Storage MissingColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30SATA, SDIO/SD/MMC, USBLowNo

Description: Hitting the eject button either in the PCManFM file manager (pcmanfm) or the Disks gnome-disk-utility tool (gnome-disks) fails as follows due to the eject command line tool being missing:
Error ejecting media
Error ejecting /dev/sda: Error spawning command-line 'eject "/dev/sda"': Failed to execute child process "eject" (No such file or directory) (g-exec-error-quark, 8) (udisks-error-quark, 0)

ELB-693FixedUnify Behaviour When Config Block Is MissingColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BootloaderLowNo

Description: Currently various things may fail or behave strangely on certain modules if the config block is missing. Unify that behaviour by e.g. rather not allowing use of any features (e.g. Ethernet, RNDIS) at all in this case.

Workaround: Use the 'cfgblock create' U-Boot command to restore the config block. Alternatively we implemented similar functionality into our Toradex Easy Installer.

ELB-681New FeatureAdd support for LM816 (RTL8188EU)Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Wi-FiLowNo

Description: Add the driver for RTL8188EU which is e.g. used in LM816 to our standard images.

ELB-675FixedSometimes the RTC Driver Recovers Invalid Date/Time from the External RTCApalis TK1RTCLowNo

Description: After the RTC has been under-powered, some RTC deliver invalid date/time. The external RTC currently shipped on Toradex evaluation boards has a oscillator fail bit which indicates when RTC does not contain a valid date/time.

ELB-671FixedFix Toradex NXP U-Boot Recipe to Work With PokyColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61BuildsystemLowNo

Description: Our 2016.11 U-Boot recipe in meta-toradex-nxp fails to build. - The RPM packaging errors out because the generated spec file contains a dash in the Release variable: Release: 2.7.2-gitr60021a4

Workaround: - Edit recipes-bsp/u-boot/u-boot-toradex_2016.11.bbappend so that the PR variable does not contain a dash ('-').

ELB-590FixedNo Longer Spawn getty on USB Serial GadgetColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61UARTLowNo

Description: On modules with newer kernels we set up a composite USB gadget with an RNDIS and a ACM USB endpoint providing a virtual Ethernet and serial link on the USB client port. Currently for Colibri VF a getty is spawned on the serial link giving you a login console on that connection. All other modules do not spawn a getty. We no longer spawn a getty on any module since some host platforms do have issues with composite USB gadgets.

Workaround: Please have a look at the following article on our developer website for more information: http://developer.toradex.com/knowledge-base/usb-device-mode-(linux)

ELB-586New FeatureRemove Unneeded RDEPENDS From Our RecipesColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Bitbake for some time checks what other packages a package depends on by e.g. examining the output of ldd of a binary or examining used interpreters in scripts. So RDEPENDS are only needed for non obvious packages, e.g. such which get dynamically linked in code or packages providing data. Cleanup our layers.

Description: Newer distros like e.g. Fedora 24 use GCC version 6 as the host (native) toolchain. Our jethro based Yocto project build is not able to build the needed native tools, among them the cross compiler on such distros.

Workaround: Use a lightweight container with an older distro as documented on our developer website.

ELB-420FixedMove to GTK+ 3 in Demo ImageColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Buildsystem, GraphicsLowNo

Description: OE migrated the sato image to GTK+ 3. This includes pcman-fm with its libfm. As lxpanel is using libfm we have to follow here or provide our own pcman-fm/libfm recipes. If we move to GTK+ 3 I guess we should do it with all GTK+ based software. e.g all of lxde/lxdm (which may have some issues), the GPIOconfig tool and tegrastats-gtk.

ELB-417New FeatureDistro Boot IntegrationColibri iMX7, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Bootloader, SDIO/SD/MMC, USBLowNo

ELB-395New FeatureImplement U-Boot SPL for Memory Bring-upApalis iMX6, Colibri iMX6Bootloader, RAMLowNo

Description: U-Boot SPL will greatly improve overall system boot flexibility.

ELB-380New FeatureConsider Using Udisks2Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Udisks development has stalled in 2014, udisks2 seems to be the successor. According to the OE recipes udisks2 also has less dependencies (notable lvm2, which adds almost 3.2MiB to the image and is not commonly used in embedded systems as well as sg3-utils, another 1.1MiB). Udisks2 also has a command line utility see: https://zeth.net/2014/05/28/modern_mounting_with_udisks2.html.

ELB-369New FeatureUpdate BCB to Support Bad Block Markers and Complete PagesColibri iMX7, Colibri VF50, Colibri VF61Bootloader, ConfigBlockLowNo

Description: So far U-Boot writes a BCB (Boot Configuration Block) crafted in a way to work around errata e9609. This also requires the U-Boot to be written in a way which only uses 3/4 of a page (implemented by the writeboot command). This mode has a drawback in practice: It cannot detect bad blocks marked with the usual bad block marker. Colibri iMX7 V1.1B and later do not suffer errata e9609. In order to overcome the limitations of the work-around, new U-Boot version will write the BCB in a new format which allows detecting bad block markers and use complete pages. This also allows to write the boot loader using standard nand write commands.

V2.6.1 Beta 2 (Release date: 2016-11-22)
This is a release for Apalis TK1 2GB V1.1A only. The January 2017 release supporting all platforms (iMX6, iMX7, VFxx, T20, T30, TK1) will follow later as V2.7 Beta 1.

ELB-570FixedPCIe Clock and Reset May not Conform to SpecificationApalis TK1PCIeLowNo

Description: Our current PEX 8605 errata workaround violates the PCIe clock and reset specification should no PCIe switch be present as e.g. the case on Ixora.

Workaround: http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_tk1_l4t_r21.5&id=3e2259b04c2e2c029f742e9dda06a3a2739977d4

ELB-569FixedUpdate Source MirrorApalis TK1BuildsystemLowNo

Description: As that whole source mirror stuff has been introduced rather haphazardly whoever did that also failed maintaining/updating it since V2.5 e.g. http://sources.toradex.com/V2.5/. The wohle process around this is currently unclear.

Workaround: http://git.toradex.com/cgit/meta-toradex-demos.git/commit/?h=jethro&id=a6c6fa422e9cf9586e0eb8aba40e0460513edf58

ELB-568New FeatureConfigure IPv6-in-IPv4 Tunnel (SIT Driver) as ModuleApalis TK1EthernetLowNo

Description: The IPv6-in-IPv4 tunnel driver creates an additional network interface (sit0). To avoid confusion around that interface and since the sit interface is only used seldom the driver should be made available as a module.

Workaround: http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_tk1_l4t_r21.5&id=1cb425d3e668e3d2b77872d5440fffd87ac9cf21

ELB-513New FeatureSupport Apalis UART4Apalis TK1UARTLowNo

Description: Support Apalis UART4.

ELB-453FixedLoading Default USB Gadget Schema FailsColibri iMX7USBLowNo

Description: Even if a USB controller is in peripheral mode, loading the USB Gadget schema fails with "Failed to start Load default USB gadget schema g1.schema.".

Workaround: Remove the command (ExecStartPost) copying the serial-number to the USB Gadget configuration in /etc/systemd/system/multi-user.target.wants/usbg.service.

ELB-450FixedBug in the Parity Control of the Vybrid lpuart DriverColibri VF50, Colibri VF61UARTLowNo

Description: There was a bug in the parity control of the Vybrid lpuart driver.

ELB-446FixedMissing RS485 HandlingApalis iMX6, Colibri iMX6UARTLowNo

Description: Our latest kernel is missing RS485 handling e.g. to use the RTS (CTS) output to control a RS485 transmitter.

Workaround: You may find the following commit from our older Linux kernel 3.10.17 as deployed in our embedded Linux BSP V2.4 Beta 1 (May 18, 2015) useful: http://git.toradex.com/cgit/linux-toradex.git/commit?h=toradex_imx_3.10.17_1.0.0_ga&id=82cf64948ddab0360fab876ee321b6191ed7258a

ELB-443New FeatureGCC-6 Usable as the CrosstoolchainApalis TK1, Colibri T20, Colibri T30, Apalis T30KernelLowNo

Description: As OE moves to GCC-6 we should provide our NVIDIA Kernel sources in a way that they can be built with gcc 6. This would allow customers taking our BSP and using it with a later Yocto project release.

ELB-442New FeatureEnable USB OTG Device/Host Detection on USBCColibri iMX7USBLowNo

Description: Automatic USB Device/Host Detection will allow to use the USB port as either Device or Host (OTG). Note: The current default on the USB client port (USBC, OTG) is to be USB host. The reason for this default is that the Colibri iMX7S modules only provide this USB port, and USB host is typically used more often than client.

Workaround: If USB device is preferred as default set the device tree "dr_mode" property of the "usbotg1" node to "peripheral".

ELB-438New FeatureEDID Causing Kernel Panic on T30Colibri T30, Apalis T30HDMI, KernelLowNo

Description: Certain EDID from HDMI screens are causing a kernel panic upon boot on T30.

ELB-396FixedU-Boot on Colibri iMX7S Freezes when Executing 'usb start'Colibri iMX7Bootloader, USBLowNo

Description: The Colibri iMX7 Solo does only have one USB port. However the bootloader code of the Alpha1 release touches registers of the not available second USB port which leads to a freeze of U-Boot.

Workaround: None.

ELB-382New FeatureAdd Fusion Displays to Simple Panel DriverColibri VF50, Colibri VF61RGBLowNo

Description: With the change to the DRM based Display Controller driver display timings are taken from a the Simple Panel driver. The Simple Panel driver does not include timings for the Fusion Capacitive Multi-Touch Displays currently.

Workaround: None.

ELB-331New FeatureLVDS Display Timing ConfigurationApalis iMX6LVDSLowNo

Description: The move to the 3.14 kernel dropped the possibility to configure the LVDS timings and resolution from the kernel command line and forced the use of the device tree. This provides that feature again.

ELB-232New FeatureSupport Ethernet L2 Switch in Vybrid SoCColibri VF50, Colibri VF61EthernetLowNo

Description: Support Vybrid's internal 10/100MBit hardware L2 Ethernet switch.

Description: Vybrid's display controller (DCU) has more capabilities then currently being supported by the frame buffer driver. Implement a Linux DRM driver to support all the features of the DCU and leverage the advanced interfaces provided by the Kernel (KMS/DRI).

Workaround: Use the DCU frame buffer driver to provide display output.

ELB-385New FeatureEthernet Communication not Possible SometimesColibri VF50, Colibri VF61EthernetLowNo

Description: On some modules in certain temperature ranges Ethernet might not work after suspend or after bringing down the network interface. The LED constantly blinks and receive/transmit errors might be reported. No frames can be received or sent in this state.

ELB-373New FeatureAudio Codec does not Restore Settings after LPSTOP2Colibri VF61Analog Audio, Power ManagementLowNo

Description: Audio settings do not get restored after suspend-to-RAM (LPSTOP2).

Workaround: Use standby (STOP) mode instead for now.

ELB-368FixedSome Modules don't Boot Reliably Because of eMMC ConfigurationApalis iMX6, Colibri iMX6BootloaderLowNo

Description: A low percentage of modules don't boot reliably because of the bootrom not handling the eMMC correctly. This leads to non booting modules. Using reset solves the problem, a power-cycle mostly works too.

Workaround: Using different i.MX6 fusing options and eMMC configurations seems to solve the problem. For the time being you may evaluate this as described in the following article on our developer website: http://developer.toradex.com/software-resources/arm-family/linux/linux-booting#eMMC_Fast_Boot_Mode_ApalisColibri_iMX6

ELB-366New FeatureFix 8m/s1 Support in LPUART DriverColibri VF50, Colibri VF61UARTLowNo

Description: When triggering the DCD signal an interrupt is generated which is not handled by the UART driver.

ELB-348New FeatureUnexporting a GPIO does not Disable the PinColibri VF50, Colibri VF61GPIOLowNo

Description: When using the unexport functionality through the GPIO sysfs interface, the pin keeps the last configured state. The typical expecation is that the pin is being disabled (set to Hi-Z).

Workaround: Set the GPIO as input before unexport.

ELB-337New FeaturePCIe Not WorkingApalis iMX6PCIeLowNo

Description: While on the Apalis Evaluation board the PCIe switch as well as plugged-in (mini-)PCIe cards usually get detected actual operation may fail.
On Ixora PCIe may fail due to a device reset/initialisation timing issue.

ELB-309FixedUSB Host does not Work after using LPSTOP Suspend ModeColibri VF50, Colibri VF61Power Management, USBLowNo

Description: The USB host (USBH) bus disconnects all devices after resuming from LPSTOP (suspend-to-memory) low-power mode.

Workaround: Use unbind before entering suspend and (re)bind the driver after suspend. This method has been implemented as a systemd service (usb-resume.service). Alternatively, use standby mode instead.

ELB-302New FeatureFix Overrun on UART RX DMAColibri VF50, Colibri VF61UARTLowNo

Description: UART receiver path can overflow in certain conditions when using DMA mode. This leads to the receive path being stuck and not receiving any character anymore.

Description: When rebooting the system using software reboot Linux can leave the PHY in an undefined state (e.g. down) in which case Ethernet may not work in U-Boot unless a hardware reset is performed.

ELB-329FixedU-Boot mmc partconf Command IssueColibri iMX6Bootloader, Flash, SDIO/SD/MMCMediumNo

Description: We are currently chasing a strange race condition/sequencing issue concerning eMMC seen on certain Colibri iMX6 modules. An affected module will continue to boot off the regular eMMC user area while our update scripts will update the one located in the boot area which may lead to quite some confusion/inconsistencies.

Workaround: Just manually enter the following from within U-Boot for now and you should be fine again:
Colibri iMX6 # mmc partconf 0 1 1 0
More information about this is available here: http://developer.toradex.com/software-resources/arm-family/linux/linux-booting#eMMC_Hardware_Boot_Area_Partitions_ApalisColibri_iMX6_and_ApalisColibri_T30

ELB-300New FeatureUBIFS Errors when File-System is FullColibri VF50, Colibri VF61Bootloader, FlashLowNo

Description: Full UBIFS root file system can lead to a system which is not able to mount the root file system anymore.

Workaround: Take measures to avoid the root file system completely running out of space.

ELB-297FixedSlow Memory CopyColibri T30, Apalis T30RAMLowNo

Description: Libc based memory copy recently slowed down by almost a factor of two.

Workaround: Use one of our V2.1 based BSPs which did not exhibit this issue.

ELB-296FixedSoftware Reboot Lock-upColibri T20KernelLowNo

Description: Rarely after about 500 software reboot cycles the module locks up during boot.

Workaround: Just power-cycle again.

ELB-226FixedRace Condition in USB OTG Device/Host Detection on IxoraApalis T30USBLowNo

Description: On Ixora with set jumper JP2 the lower X8 USB host port (shared with the X9 micro USB port) is not reliably working. There seems to be a race condition in NVIDIA's USB OTG driver concerning the loading and binding of the USB device gadget driver which prevents Apalis USBO1 being operational in host mode.

Description: A race condition during boot may cause a different order of native aka on-module HDMI vs. on-carrier I2S audio devices.

Workaround: Do not use the soundcard device index to identify the output (e.g. based on aplay -l output).

ELB-4326Known IssueTK1: Kernel oopsApalis TK1LowNo

Description: The kernel is not stable, sometime kernel `BUG at mm/page_alloc.c` is reported at runtime.

ELB-4279Known IssueCurrent U-Boot SPL Incompatible With Former aka BSP 2.8.x U-BootApalis iMX6, Colibri iMX6BootloaderLowNo

Description: Unfortunately, the current U-Boot SPL is incompatible with the former aka BSP 2.8.x U-Boot. This may be an issue if trying to install a BSP 2.8.x using the legacy update procedure. Using the Toradex Easy Installer does not exhibit this issue.

Workaround: Using the Toradex Easy Installer does not exhibit this issue. If you absolutely have to use the legacy update procedure make sure to also explicitly separately update the U-Boot SPL as well e.g. as follows:
run setupdate
run update_spl
run update

ELB-4254Feature RequestIncrease SPI Datarate Efficiency on ECSPI DriverVerdin iMX8M PlusSPINo

Description: We can see approximately 1 byte of pause between each byte sent using `spidev_test` utility from kernel-sources in `tools/spi/spidev_test.c`. Improve the ECSPI driver in a way that the DMA can be used more efficiently.

Workaround: You can disable DMA in device-tree with "/delete-property/ dmas; /delete-property/ dma-names;" in ecspi node. Further it is possible to play with the "bits-per-word" setting of spidev_test.

ELB-4200Known IssueWrong USB PHY TX register value set from devicetreeApalis iMX8USBLowNo

Description: USB PHY tx calibration for TXCAL45 using devicetree (https://www.kernel.org/doc/Documentation/devicetree/bindings/phy/mxs-usb-phy.txt) is not correct on iMX8 SoC. For TXCAL45DP and TXCAL45DM the dts configured range is 30-55 Ohm, but the USB PHY TX range is 35-54 Ohm.

Workaround: Scale `fsl,tx-cal-45-dp-ohms` and `fsl,tx-cal-45-dn-ohms` to ensure you get the desired value in the USB PHY registers.

ELB-4125Known IssueQt5_CinematicExperience Stuck at BootApalis iMX8GraphicsLowNo

Description: With some 4K HDMI screen (for example Philips Brilliance 288P6L) the Qt5_CinematicExperience gets stuck at boot most of the time. Lowering the resolution to 1080p via weston.ini improves it slightly but still gets stuck more than 2/3 of the time.

Workaround: Just re-starting the demo as follows works reliably:
systemctl restart wayland-app-launch

ELB-4083Known IssueStop PCIe Endpoint Results in WarningApalis iMX6, Apalis iMX8, Apalis iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusPCIeLowNo

Description: After an endpoint is started through configfs, if 0 is written to the configfs entry 'start', the controller stops but the epc_group->start value remains 1. A subsequent unlinking of the function from the controller would trigger a spurious WARN_ON_ONCE() in pci_epc_epf_unlink() despite right behavior.

Workaround: https://github.com/torvalds/linux/commit/f58d5f53c89479c12ad719c1960176442add5aaa

ELB-4066Known IssueSODIMM_45 Powers Down Colibri T30 Instead of Wake up From SuspendApalis T30, Colibri T30Power ManagementMediumNo

Description: The pin SODIMM_45 (WAKE1) is usually used for waking up a module from suspend. However transitioning SODIMM_45 from 0V to 3.3V triggers the module to power down.

Workaround: Change the logind configuration to ignore 'power key' key presses.
Set in /etc/systemd/logind.conf:
HandlePowerKey=ignore

ELB-4054Known IssueU-Boot `cfgblock create` Command Does Not Do Any Plausibility ChecksApalis iMX6, Apalis iMX8, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBootloader, ConfigBlockLowNo

Description: We saw minor artifacts in the form of approximately 5mm long grey 1px high bars that are randomly blink on the left side of the screen. This issue depends on if either &display_lcdif or &adma_lcdif in device tree.

ELB-3039Known IssueConcurrent Use of SDIO Wi-Fi and Bluetooth May Crash Firmware/DriverColibri iMX6ULL, Verdin iMX8M Mini, Verdin iMX8M PlusBluetooth, Wi-FiLowNo

Description: Simultaneous use of Wi-Fi and Bluetooth interfaces can lead to crashes of the firmware and/or the Linux kernel driver of the SDIO Wi-Fi/BT solution.

Workaround: Unload (rmmod) the entire Wi-Fi and Bluetooth stack and reload (insmod) it again. Worst case an entire system reboot may be required. Note: NXP is still working on the concurrent Wi-Fi Bluetooth use case.

ELB-3011Feature RequestImprove Memory SpeedApalis iMX6RAMNo

Description: Memory speed (e.g. tinymembench) is below results from older BSPs. Unfortunately, this is a userspace issue which is known and e.g. also discussed on NXP's public forum: https://community.nxp.com/t5/i-MX-Processors/IMX6Q-poor-memory-performance/m-p/903644 https://community.nxp.com/t5/i-MX-Processors/Cortex-A9-ARM-Errata-845369/m-p/399972

Workaround: Currently, the only quick solution is to revert to using the former userspace.

ELB-2957Feature RequestUSBH_EN is Asserted UnconditionallyApalis iMX8USBNo

Description: The signal USBH_EN controls for all USB Hosts (USBH2, USBH3, and USBH4) the VBUS voltage switches on the carrier board. The driver for USBH4 does not provide a functionality to control USBH_EN. Thus the regulator reg_usb_host_vbus is configured to be always on in the device tree. Otherwise VBUS wouldn't be on if one would disable USBH2 and USBH3.

ELB-2956Feature RequestFix X11 xorg.conf for Mainline KernelColibri iMX6ULL, Colibri iMX7GraphicsNo

Description: On Colibri iMX6ULL and Colibri iMX7 X11 does not work out of the box if using a mainline kernel.

ELB-2876Known IssueApalis TK1 V1.2A.003 with Micron eMMC may experience Timeout Errors due to Non-Conformant RPMB AccessesApalis TK1FlashLowNo

Description: Many eMMC devices have a special partition called RPMB (replay protected memory block). Any access to this partition is protected by a OTP key (our modules are shipped with no key, customer can upload one if they choose to use this partition). Access to this partition can only be done using special commands. Our BSP images provide a utility (mmc-utils-cos) which handles read/write/fuse operations for the RPMB. However, due to the way Linux operates we also need to create a device node in devfs. This creates a special file called /dev/mmcblk0rpmb. Since this is a valid device file it may be opened/read/written by any OS utility and such calls will be translated into requests to the eMMC chip. Unfortunately, those would be invalid eMMC requests. And here is where the difference between Micron and Toshiba eMMC parts shows. Toshiba parts answer invalid data reads with zeros while Micron parts ignore them triggering the kernel timeout mechanism. Since the request is invalid both behaviours may be considered valid. However, modules with Micron eMMC parts may experience lengthy delays due to such timeout processing. When accessed correctly (via the mmc utility) the RPMB works correctly in exactly the same way on both vendor's eMMC parts.

Workaround: Applying the following patch avoids experiencing lengthy delays due to such timeout processing: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4e93b9a6abc0d028daf3c8a00cb77b679d8a4df4

ELB-2645Known IssueSoftware Reset does not do a full System ResetApalis iMX8, Apalis iMX8X, Colibri iMX8XSCFWLowNo

Description: A major feature of NXP's BSP L4.14.98_2.3.1_patch was to add support for partition reset. This will reset only a part of the SoC. It does not rerun the ROM so code will not be reloaded. This is the most common way i.MX 8/8X customers do reset as they don’t want the M4 to reset if the AP needs to reset. So software reset will not reboot the whole system anymore, only the AP partition. You can revert this by following below workaround.

Workaround: A complete system reset is still supported. However, the default ATF does a partition reset, not a board reset. It will have to be modified to do a board reset. It will need to call sc_pm_reset() rather than sc_pm_reboot() or sc_pm_reboot_partition(). So from the customer's perspective, this was a change in ATF that they will have to revert. They should be porting ATF for their use case anyway.

ELB-1183Known IssueBoot Error "commit machine-id"Colibri T20, Colibri T30, Apalis T30KernelLowNo

Description: There may be a boot error reported concerning "commit machine-id". This is caused by an incompatibility between later systemd version and the downstream NVIDIA L4T R16.5 based Linux kernel 3.1.10. However, no further adverse effect has been discovered.

Workaround: Running a mainline based Linux kernel does not exhibit this issue.

ELB-1181Known IssueApalis iMX6 HDMI EDID Not Following SpecificationApalis iMX6HDMILowNo

Description: Apalis iMX6 is not reading the full content of EDID but rather only parts of it. Exact behaviour also depends on the U-Boot environment variable vidargs.

ELB-1180Known IssueApalis iMX6 HDMI EDID Frequency Exceeds 100 kHzApalis iMX6HDMILowNo

Description: The Apalis iMX6 HDMI EDID frequency exceeds the 100 kHz as per specification.

ELB-1176Known IssueWatchdog on iMX7 not Disabled when Pressing the Reset Button (Hard Reset)Colibri iMX7WatchdogLowNo

Description: If the watchdog on Colibri iMX7 gets triggered and the module is reset without power-cycling, then the watchdog does not get disabled. This is due to the errata #e10574 described in Errata NXP Document (https://www.nxp.com/docs/en/errata/IMX7D_2N09P.pdf), which described that the internal watchdog of the i.MX 7 SoC is not working properly. Therefore, the hardware watchdog as integrated in the PIMIC is used on our module to provide the watchdog functionality. Unfortunately, this hardware watchdog can only be reset by a full power-cycle of the module.

ELB-1174Feature RequestBoot Logo not Shown on HDMI OutputApalis iMX6, Colibri iMX6HDMILowNo

Description: When the kernel boots the display shows a boot logo (by default Tux) along with kernel messages.
If one uses the HDMI output that logo is not shown due to the initialization sequence the IPU driver goes through.

Workaround: See: http://www.toradex.com/community/answers/34554/view.html

ELB-1173Known IssueColibri VF50 128MB IT V1.2B May Not Wake-up From Software SuspendColibri VF50Power ManagementLowNo

Description: While the CAN transceiver regulator is properly powered-down on non-use such functionality during suspend is currently missing in flexcan.c.

Workaround: A custom power-down GPIO may be implemented.

ELB-1162Known IssueRegression on Resume With rootfs on NFSApalis iMX6EthernetLowNo

Description: On resuming from a sleep state systemd-journal may hang and print dump messages due to potential slow re-connection to the Ethernet PHY.

Workaround: After resuming the Ethernet PHY may need up to 15 seconds to re-connect its link. After this time, Linux will recover and the module is back to full functionality.

ELB-1161Known IssueSpurious Errors Shown During Legacy Update ProcedureApalis TK1, Colibri T30, Apalis T30BootloaderLowNo

Description: During the legacy update procedure running e.g.:
run setupdate
run update
May show the following spurious errors which can usually be ignored:
MMC read: dev # 0, block # 16383, count 1 ... MMC: block number 0x4000 exceeds max(0x2000)
0 blocks read: ERROR
This has to do with various eMMC parts featuring different eMMC hardware boot area partition sizes which get probed by the legacy U-Boot update scripts potentially showing missleading error messages.

Workaround: Just ignore such error messages during the legacy update procedure.

ELB-1159Known IssueUSB devices fail to initialize through a USB HubColibri iMX7USBLowNo

Description: USB devices don't get properly initialized when connected at boot through a USB Hub (usb usb1-port1: cannot reset (err = -32)).

Workaround: There are several workarounds: 1. Adding 900 ms on the init2 of hub_activate function (drivers/usb/core). 2. Using a direct USB connection (instead of using a USB Hub connection). 3. Wait for Linux to finish booting to connect the USB.

ELB-1157Known IssueSoftware Reset Doesn't Always Work CorrectlyColibri T20Bootloader, KernelLowNo

Description: Some modules sometimes do not boot after a software reset.

Workaround: Triggering a reset via PMIC reliably initiates a hard reset e.g. doing the following from within U-Boot:
i2c dev 0
i2c mw 0x34 0x14 1 0x01

ELB-1140Known IssueColibri iMX6ULL: Booting Again After poweroff When an SD Card is Inserted or RemovedColibri iMX6ULLPower ManagementLowNo

Description: For single antenna set single_rf=0x01

ELB-1116Feature RequestT20/T30 Internal Video DAC OutputColibri T20, Colibri T30, Apalis T30Graphics, VGALowNo

Description: The T20 SoC internal video DAC output is unsupported by NVIDIA's L4T Linux SW stack our BSP is based on. The T30 SoC does not even support any internal video DAC functionality according to NVIDIA's latest specification.

Workaround: Use an external video DAC on the carrier board similar as to what may be found on our Colibri Evaluation board, Iris or Aster.

ELB-1114Feature RequestMainline TK1 LVDS SupportApalis TK1LVDSLowNo

Description: LVDS is currently not supported in mainline. Please contact Toradex if you need this feature in mainline.

Workaround: Use downstream L4T kernel which does support LVDS.

ELB-1111Known IssueUART Input OverrunColibri T20, Colibri T30, Apalis T30UARTLowNo

Description: Certain use-cases may cause UART input overruns.

Workaround: Disabling DMA may help but ultimately this got fixed in the Linux kernel 4.19.

ELB-1110Known IssueLM006 on Apalis iMX6 not Stable on RebootsApalis iMX6Wi-FiLowNo

Description: Initialization of LM006 not stable on reboots on Apalis iMX6 IT modules.

ELB-2708Known IssueDifferentiate between Reset Power On Request and Watchdog ResetColibri iMX7WatchdogLowNo

Description: At the moment for iMX7 it is not possible to identify the Reset Reason. For future at least the Reset POR should be differentiated from Watchdog Reset.

ELB-1091Known IssueUSB OTG Configured for USB 3.0 Operation may get Stuck in Host ModeApalis TK1USBLowNo

Description: USB OTG configured for USB 3.0 operation may get stuck in host mode on Apalis TK1.

Workaround: If you need full OTG functionality do use USB 2.0 mode only which is now the default as of BSP 2.8b6.

ELB-1072Known IssueLXPanel at Wrong Position With Some Screen ResolutionsApalis TK1Graphics, HDMI, LVDSLowNo

Description: The LXPanel is showing in a wrong position when opened with certain display resolutions.

Workaround: It is possible to get rid of this bug by choosing different display resolutions using xrandr. It also seems this bug is only appearing when using two displays. Try to only use one display.

ELB-1058Feature RequestAdd support for new [00471001] Apalis iMX8QM 4GB IT V1.0BApalis iMX8KernelLowNo

Description: Support the new product version [00471001] Apalis iMX8QM 4GB IT V1.0B with our embedded Linux BSP.

Workaround: Switch RX and TX and use DTE Mode. or
Don't set the UFCR_DCEDTE mode bit in U-Boot. (board/toradex/'module'/'module'.c

ELB-1040Known IssueAdding Locale and Language to Linux Image Build has no EffectApalis iMX6BuildsystemLowNo

Description: During an Open-Embedded Build, the added locale and language for the system are not included in the final image.

Workaround: Since the value of the variable IMAGE_LINGUAS=“pl-pl en-us” in local.conf is overruled by the value coming from the image recipe, it is not possible to set the needed value from the local.conf. However one can append the language by adding IMAGE_LINGUAS_append = ” pl-pl” in local.conf.

ELB-1025Known IssueNative compilation using arm-angstrom-linux-gnueabi-gcc not working with GCC 7.2 and aboveColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Apalis T30BuildsystemLowNo

Description: Currently native Compilation is not working in the regular Bsp (version > 2.8) due to a mismatch of GCC libraries.

Workaround: Do cross-compilation or create a custom image with GCC being pre-installed.
IMAGE_INSTALL_append = " packagegroup-sdk-target"

ELB-1019Feature RequestProvide Hooks to Easily Deploy M4 BinariesColibri iMX8X, Colibri iMX7, Colibri VF61, Apalis iMX8BuildsystemLowNo

Description: On modules with a SoC having an additional M4 core one might want to deploy firmware through our regular image build process. Add a hook to simplify that deploy process. Do this for our legacy update procedure and for the Toradex Easy Installer.

ELB-1013Known IssueLegacy Update Procedure Fails on Colibri VF50 128MB With Regular LXDE Demo ImageColibri VF50RAMLowNo

Description: The legacy update procedure fails at the reading ubifs.img step. Due to the limited amount of RAM available, the full LXDE demo image simply won't fit.

Workaround: Please use the console-tdx-image aka Colibri-VF_Console-Image on the Colibri VF50 instead.

ELB-1003Known IssueHDMI HDA Audio IssuesColibri T20, Colibri T30, Apalis T30Digital Audio, HDMILowNo

Description: HDMI HDA resp. I2S audio may not work with certain screens depending on available display modes and pixel clock frequencies. HDMI HDA resp. I2S audio may also not work after hot-plugging.

Workaround: Make sure to use vidargs selecting a HDMI audio capable pixel clock frequency. Do not hot-plug resp. power-cycle after plugging in HDMI. If you keep having issues try another brand/model screen.

ELB-1002Known IssueU-Boot Splash Screen Not WorkingApalis TK1, Colibri T20, Colibri T30, Apalis T30BootloaderLowNo

Description: On Colibri T20 and Apalis/Colibri T30 the famebuffer console output is shown rather than an image splash screen due to differences in graphics stacks. On Apalis TK1 there is currently no framebuffer support.

Workaround: You may use a Linux kernel or user space splash screen.

ELB-1001Known IssueOpenCV4Tegra Has Missing Run-Time DependenciesApalis TK1CSI, GraphicsLowNo

Description: OpenCV4Tegra currently may fail due to "run-time" dependencies:
cd /usr/lib/; find . -name 'libopencv*so*' -exec ldd {} + | grep 'not found' | sort | uniq
libavcodec.so.54 => not found

ELB-993Known IssueResume Crashes on Raw NAND DevicesColibri iMX7Power ManagementLowNo

Description: Using default suspend to memory (i.MX 7 DSM, deep sleep mode) seems to crash on wake-up.

Workaround: Use latest stable.

ELB-990Known IssuePaths in a SDK's qmake Project Include Files are not RelocatedApalis TK1BuildsystemLowNo

Description: If one builds an SDK for Qt5 one gets qmake project include files (*.pri) which contain paths valid for the build host used to compile the SDK rather than paths relocated to where one extracted the SDK to.

Workaround: Fix the paths, e.g. have a look at this community thread: https://www.toradex.com/community/questions/24918/strange-paths-when-installing-angstrom-sdk-for-teg.html

ELB-978Known IssueLegacy Update Procedure May Fail With Bigger ImagesColibri iMX7, Colibri VF50, Colibri T20FlashMediumNo

Description: On NAND flash based modules like the Colibri T20, the legacy update procedure depends on first loading the entire root file system image into RAM. If your custom image is significantly larger than our regular demo images it may no longer easily fit into 256MB of RAM, therefore, failing the legacy update procedure (it may just hang or even crash but definitely fails to update the root file system).

Workaround: Doing the following before 'run setupdate; run update' may help to a certain extend:
setenv fdt_addr_r 0x01000000
However, even bigger images may still fail requiring a different flashing strategy altogether (e.g. initially booting from an initrd or via NFS subsequently updating the root file system from within Linux on-the-fly.

ELB-977Known IssueConcurrent Dual CSI-2 Camera FailingApalis T30CSILowNo

Description: Concurrent dual CSI-2 camera is currently failing on Apalis T30. It is working fine on Apalis TK1.

Workaround: Apalis TK1 would support this.

ELB-976Known IssueYear 2038 IssueColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Kernel, Miscellaneous Peripherals, RTCLowNo

Description: On 32-bit systems, Linux uses a 32-bit signed integer type 'time_t' to represent the time at various locations. It gives the time as seconds relative to 1970. The time_t type wraps at "2038-01-19 03:14:07", so all users of time_t likely fail when a type_t instance is set to a timer after that date. This issue is applicable to all 32-bit systems and will be fixed in the mainline eventually.

ELB-975Known IssueLXDE, Moved Desktop Icons are not Redrawn AutomaticallyColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30RGBLowNo

Description: If one moves desktop icons in LXDE they are not redrawn automatically.

Workaround: Click anywhere on the desktop and the icons reappear at the position they have been moved to.

ELB-950Known IssueETH1_LINK LED Only Showing Gigabit Link StateApalis TK1, Apalis T30EthernetLowNo

Description: The ETH1_LINK LED is only lighting up if a Gigabit link is established. If the link is only 10 Mbps or Fast Ethernet the LED currently does not show any link.

ELB-938Known Issuesystemd udisks2 Linux Kernel Incompatibility Causing Power-Off After Unmount of USB Mass Storage Devices to FailColibri T20, Colibri T30, Apalis T30Kernel, SATA, SDIO/SD/MMC, USBLowNo

Description: An incompatibility between the downstream Linux kernel 3.1.10 and systemd in conjunction with udisks2 is causing power-off after unmount of USB mass storage devices to fail as follows:
root@apalis-t30:~# udisksctl power-off -b /dev/sda
Error powering off drive: Error opening /dev/sda: Device or resource busy (udisks-error-quark, 0)
Note: As a side effect subsequently plugged in USB mass storage devices may also get increasing device node names even though previous ones already got unplugged beforehand (e.g. sdb, sdc etc.).

Workaround: Do not use systemd or upgrade to the mainline Linux kernel.

ELB-924Known IssueColibri iMX6ULL WB IT 1.0A Modules Fail to Read UBIFSColibri iMX6ULLFlashMediumNo

Description: Colibri iMX6ULL 512MB WB IT V1.0A sometimes fails to read UBIFS when the temperature is below 0°C. This issue was not detected on later version of Colibri iMX6ULL 512MB WB IT

ELB-922Known IssueData Abort When Starting Linux After Starting Cortex-M4 Firmware From DDRColibri iMX7BootloaderLowNo

Description: After starting the Cortex-M4 firmware from DDR, U-Boot causes a data abort when trying to load Linux.

Workaround: As a workaround you may try
U-Boot: setenv defargs mem=512M; saveenv
freertos-toradex\platform\devices\MCIMX7D\linker\gcc\MCIMX7D_M4_ddr.ld: Change the following line: line 60 m_data -> ORIGIN: 0x8ff80000 LENGTH 0x00070000

Alternatively, start the M4 firmware from OCRAM.

ELB-919Known IssueApalis TK1 HDMI Unplug With LVDS Connected Leaves HDMI as a Primary DisplayApalis TK1Capacitive Touch, Graphics, Resistive TouchLowNo

Description: Unplugging HDMI after running HDMI and LVDS/eDP will not reconfigure display and touch layout.

Workaround: Don't use HDMI hotplug together with other displays.

ELB-918Known IssueUserspace Crash Observed on Powerdown or RebootApalis iMX6Miscellaneous PeripheralsLowNo

Description: Some user space process may crash on power down or re-boot.

ELB-912Feature RequestProvide Code/Support for ADC and SPI Peripherial Using the M4 Core of Colibri VF61Colibri VF61Analog Inputs, CPU, SPILowNo

Description: NXP doesn't provide any support for FreeRTOS and is not writing peripheral drivers for ADC and SPI on Vybrid.

Workaround: FreeRTOS on i.MX 7 provides support for ADC and SPI. It might be taken as a base for a port to Vybrid modules. This has not been verified by Toradex.

ELB-911Known IssuePlaying Wavefile on Apalis T30 using Java makes the Kernel freezeColibri T30, Apalis T30Analog AudioLowNo

Description: This has initially been observed using JDK 1.8.0_121 on our stable BSP 2.6 but the system still does freeze as of JDK 1.8.0_152 on BSP 2.8b3. There seems to be a race condition within the clocking and/or DMA subsystems caused by Java's rather special way of doing ALSA.

Workaround: Playing MIDI files instead seems to work. Alternatively, using the mainline Linux kernel playing a wavefile using the same Java versions also works just fine.

ELB-888Known IssueUnable to control CPUquiet settings on Apalis TK1Apalis TK1KernelLowNo

Description: On Apalis TK1 running 3.10 kernel it's impossible to control CPUquiet using sysfs. CPU on/off schedulesr provided in kernel always operates in automatic mode. CPUquit can be disabled by disabling CONFIG_CPUQUIET_FRAMEWORK and CONFIG_TEGRA_AUTO_HOTPLUG in kernel config (all 4 cores will be permanently active, and low power core will be disabled)

ELB-884Feature RequestAdd CDC ECM ConfigurationColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis iMX8USBLowNo

Description: Add CDC ECM Configuration.

Description: LM816 Wi-Fi speed is limited to 1 Mbit/s rx/tx.

Workaround: Updating to a later Wi-Fi backports may help but only marginally.

ELB-851Known IssueRESET_MOCI is Kept in Reset Until Linux Probes PCIe DriverApalis iMX6, Apalis TK1Bootloader, RGB, USBLowNo

Description: U-Boot does not de-assert the RESET_MOCI signal. RESET_MOCI needs to be pulled during PCIe driver initialization sequence. In order to not reset again during Linux boot we do not de-assert RESET_MOCI in the bootloader. Due to this all components on the carrier board connected to RESET_MOCI are kept in their reset state too. On the Evaluation Board that is notably the USB Hub and a display connected to the Unified Interface Display Connector.

Workaround: One may release RESET_MOCI in the bootloader code if needed. During Kernel boot RESET_MOCI will be asserted again for 100ms during PCIe initialization.

ELB-845Known IssueDisconnecting MIPI CSI-2 Camera May Lead to System FreezeApalis TK1CSILowNo

Description: Disconnecting MIPI CSI-2 camera may lead to system freeze.

Workaround: Make sure your camera sensor provides a continuous data stream or stop the capturing first and then allow unplugging.

ELB-843Known Issue32-bit Deployment Tools Interferes with OpenEmbedded UBIFS Image TypeColibri iMX7, Colibri iMX6ULL, Colibri VF50, Colibri VF61BuildsystemLowNo

Description: When using UBIFS image type the resulting image is not bootable. Systemd fails to mount file systems and ultimately drops into an emergency shell. The reason is that the resulting image has wrong user/group ids assigned to directories and files.

Workaround: The utility mkfs.ubifs is compiled as a 32-bit binary for the legacy image format. Make sure to remove the 32-bit flag by removing meta-toradex-(demos|bsp-common)/recipes-devtools/mtd/mtd-utils_%.bbappend.

ELB-825Known IssueExternal HDA Audio Codec not AvailableApalis TK1Digital AudioLowNo

Description: HDA is currently not supported on the digital audio interface DAP1. Therefore the Realtek ALC898 HD audio codec as assembled on the Apalis Evaluation Board won't work.

Workaround: You may use any Linux supported I2S codec like e.g. the SGTL5000 from NXP (formerly Freescale). Please note that custom software adoptions will be required.

ELB-811Known IssueHigh Current on V_Batt After PoweroffColibri iMX6ULLRTCLowNo

Description: When a Colibri iMX6ULL is shut down with the 'halt' command and the main power supply is then switched off VCC_BATT consumes the to expected 20 μA. If it is shut down with the 'poweroff' command and the main power supply is then switched off VCC_BATT consumes 320 μA.

ELB-803Known IssueIncrease Resistive Touch Panel Calibration ToleranceApalis TK1Resistive TouchLowNo

Description: Especially on Apalis TK1 where we use full 12-bit capable ADCs the default 15 pixel tolerance is way too small causing frequent misclicks.

Workaround: You may increase the misclick tolerance as follows: sed -i 's/\(BINARY=\"xinput_calibrator\)/\1 --misclick 100/' /usr/bin/xinput_calibrator_once.sh

ELB-801Known IssueFailing I2C Transactions May Freeze Apalis TK1Apalis TK1I2CLowNo

Description: Unfortunately failing I2C transactions (e.g. due to faulty hardware or misconfiguration) may freeze Apalis TK1.

ELB-782Known IssueFix Toradex NXP U-Boot Recipe To Work From the Correct Machine ConfigurationApalis iMX6, Colibri iMX6BuildsystemLowNo

Description: Our 2016.11 U-Boot recipe in meta-toradex-nxp fails to build. - For iMX6 there may be issues with what machine file is taken depending on the sort order in bblayers.conf as the one in meta-freescale-3rdparty does not (yet) know about SPL.

Workaround: - Sort build/conf/bblayers.conf so that meta-freescale-3rdparty is after meta-toradex-nxp.

ELB-770Known IssueUpdated Recipe for devmem2 Might Cause LIC_FILES_CHKSUM ErrorColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Workaround: Execute the following: bitbake -c cleanall devmem2

ELB-769Known IssueOnly 256MB of RAM Available When Installing V2.6 on a Colibri iMX6DL Directly From Toradex Easy Installer U-Boot Due to Missing patch_ddr_size CommandColibri iMX6BootloaderLowNo

Description: During installation of V2.6 directly from the Toradex Easy Installer U-Boot the following error message is shown but otherwise ignored by the installation procedure: Unknown command 'patch_ddr_size' - try 'help' As a consequence only 256MB of RAM will be available.

Workaround: Just manually execute the patch_ddr_size command once U-Boot from V2.6 is installed. For existing production programming scenarios we do recommend to first separately update just U-Boot only (e.g. doing run setupdate; run update_uboot; reset) in order to make sure any further production programming scripting will proceed as before.

Description: For unknown reason /etc/profile does not get properly sourced upon graphical login. Not only does the shell prompt look strange in a desktop terminal but fw_setenv also does not work as it is missing some configuration: When using fw_setenv from a modules desktop environment one gets an error indicating that the boot partition is not writable. sh-4.3# fw_setenv x z Write error on /dev/mmcblk0boot0: Operation not permitted Error: can't write fw_env to flash

Workaround: Revert to a serial terminal or just manually source /etc/profile which will also properly configure fw_setenv: sh-4.3# . /etc/profile root@apalis-t30:~#

ELB-754Known IssueEthernet Adapter Timestamp Not AdvancingApalis iMX6EthernetLowNo

Description: When asking PCAP to provide adapter timestamps (unsynced) the provided timestamp are not advancing. This is a hardware limitation.

ELB-731Known IssueHigh Number of Byte Transfers Using SPI, Reports an IO Error in DMA ReceptionColibri iMX7SPILowNo

Description: High number of byte transfers using SPI, reports an IO error in DMA reception.

Workaround: This works with mainline

ELB-710Known IssuePoweroff/Shutdown May be Delayed for 1min 30sApalis iMX6Power ManagementLowNo

Description: Poweroff/shutdown may be delayed for 1min 30s.

Workaround: Just keep waiting.

ELB-706Known IssueFew Colibri iMX7S Were Delivered With a Constant MAC AddressColibri iMX7EthernetLowNo

Description: In the testing of Colibri iMX7S the U-Boot environment variable 'ethaddr' was set to the value '00:14:2d:12:34:56' and thus cloaking the value set in the configblock. Our test procedure has been updated in order for a regular MAC address being used.

Workaround: Deleting the U-Boot environment variable ethaddr fixes the issue. This can be done by any of the following: 1) flashing an image 2) setenv ethaddr; saveenv 3) env default -a; saveenv

ELB-702Known IssueNTSC Decoding With ACA (ADV7280 Resp. ADV7280-M)Apalis TK1, Colibri T20, Colibri T30, Apalis T30Camera Parallel Interface, CSILowNo

Description: While the ADV7280 as found on our new Analogue Camera Adapter should allow for NTSC decoding it currently seems not to work properly. The same issue has been observed using the CSI version ADV7280-M on Apalis T30/TK1.

Workaround: Apalis/Colibri iMX6 is known to work with NTSC input on ACA. The same applies to using the CSI version ADV7280-M on Apalis iMX6.

ELB-696Known IssueU-Boot Crashes When Accessing USB Flash DrivesColibri iMX7Bootloader, USBLowNo

Description: When using U-Boot to access a USB flash drive (e.g. to update the module) U-Boot may reboot immediately.

Workaround: Not all flash drives lead to this behavior, using a different flash drive might work.

ELB-692Known IssueUSB Memory Sticks Not Working Reliably in U-BootColibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30, Apalis iMX8Bootloader, USBLowNo

Description: Unfortunately U-Boot's USB functionality may be rather limited.

Workaround: Usually using a different brand/model USB stick may prove working just fine. Alternatively USB SD card readers seem to work rather better.

ELB-691Known IssueRNDIS Does Not Work When Config Block Is MissingColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61Bootloader, USBLowNo

Description: The usbg.service fails to start if the config block is missing. As a result the RNDIS network is not started on the USBC port.

Workaround: Either restore the configblock in U-Boot or start the usb gadget from the Linux command line: echo `ls /sys/class/udc/` > /sys/kernel/config/usb_gadget/g1/UDC

ELB-687Known IssueGPIO Poweroff via Device TreeColibri iMX7, Apalis iMX6, Colibri iMX6Device Tree, GPIO, Power ManagementLowNo

Description: GPIO poweroff is currently gated by CONFIG_POWER_RESET_GPIO which is not documented on our developer website. Rather use the device tree property (e.g. /soc/fsl,use-lpm-poweroff) like implemented on Vybrid.

Workaround: Re-compile the kernel with CONFIG_POWER_RESET and CONFIG_POWER_RESET_GPIO enabled.

ELB-676Feature RequestBackport Mainline SGTL5000 Commits Into Apalis TK1 BranchApalis TK1Analog AudioLowNo

Description: Mainline has a number of patches for the SGTL5000 Audio Codec driver, among them the possibility to have multiple instances of the driver running. Test if they can easily be backported into the Apalis TK1 branch.

ELB-674Known IssueSometimes the RTC Driver Recovers Invalid Date/Time from the External RTCColibri T20, Colibri T30, Apalis T30RTCLowNo

Description: After the RTC has been under-powered, some RTC deliver invalid date/time. The external RTC currently shipped on Toradex evaluation boards has a oscillator fail bit which indicates when RTC does not contain a valid date/time.

ELB-655Known IssueeDP Link Training IssueApalis TK1eDP, GraphicsLowNo

Description: Depending on the specific bridge chip or panel used the eDP link training may fail.

Workaround: As the driver fails to adjust the pre-emphasis during link training one can hack the driver to start with a higher initial pre-emphasis value. A possible way to achieve this may be found documented at https://developer.toradex.com/knowledge-base/display-output-resolution-and-timings-linux#Apalis_TK1_eDP_Output

ELB-647Known IssueUBI/UBIFS Issues on Colibri VF50/VF61Colibri VF50, Colibri VF61FlashMediumNo

Description: On Colibri VF50/VF61 in situations with frequent unexpected power-cuts, there is a possibility of filesystem getting corrupted. The issue is related to extended filesystem attributes (xattrs). Release V2.6b6 allows to disable the extended attributes through the Kconfig config symbol CONFIG_UBIFS_FS_XATTR.

ELB-645Known IssueEthernet Switch Not Monitoring External Ethernet PortsColibri VF50, Colibri VF61Ethernet, KernelLowNo

Description: The current Ethernet switch implementation does not allow monitoring the external Ethernet ports. Further Linux switchdev subsystem integration would be needed.

ELB-643Known IssueADV7280 Driver Reports Wrong Framerate Due To DeinterlacerApalis iMX6, Colibri iMX6Camera Parallel InterfaceLowNo

Description: The ADV7280 Video ADC used on the Analog Camera Module ACA is capabable of deinterlacing video. In doing so it creates a full frame for each half frame and thus doubles the framerate. When feeding the video stream into gstreamer the original framerate is assumed to still be valid. That will not be noticed if the stream is immediately displayed, however when the stream is recorded in a file the framerate gets wrongly coded and thus the resulting stream runs at 50% of its original speed.

Workaround: Disable the deinterlacer in the driver, recompile and deploy the kernel module. Comment the HW_DEINT macro: http://git.toradex.com/cgit/linux-toradex.git/tree/drivers/media/platform/mxc/capture/adv7280.c?h=toradex_4.1-2.0.x-imx#n118 The following gstreamer pipeline also works as a solution without disabling hardware deinterlace: gst-launch-1.0 -e -v \ imxv4l2videosrc do-timestamp=true crop-meta-x=16 crop-meta-y=16 crop-meta-width=660 crop-meta-height=522 ! \ textoverlay text="Hello_World" shaded-background=1 font-desc="Arial 22px" ! \ tee name=tx \ tx. ! \ vpuenc_mpeg4 bitrate=1000 ! queue ! mux. \ tx. ! \ imxeglvivsink \ alsasrc do-timestamp=true ! audio/x-raw, format=S16LE, rate=44100, channels=2 ! \ imxmp3audioenc bitrate=96 ! queue ! mux. \ avimux name=mux ! \ filesink sync=true location=video.avi

ELB-641Feature RequestImplement and Validate LPSR Suspend/Low-Power ModeColibri iMX7Power ManagementLowNo

Description: Implement and validate LPSR suspend/low-power mode.

Workaround: Suspend/Low-Power mode using DSM works.

ELB-640Feature RequestTest LP0 Low-Power/Suspend ModeApalis TK1Power ManagementLowNo

Description: Test LP0 low-power/suspend mode.

Workaround: Use LP1 which is default starting with 2.7b2

ELB-638Known IssueU-Boot: Certain USB Memory Sticks May Not Work Reliably Behind a USB HubColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BootloaderLowNo

Description: Certain USB memory sticks may not work reliably behind a USB hub. Please note that some (Apalis) if not all (Colibri) USB sockets on our evaluation boards are always behind an on-carrier USB hub.

Workaround: Switch to a different carrier board without an on-carrier USB hub like Iris or Ixora, try a different brand USB memory stick or revert to a completely different update media like an SD card.

ELB-624Known IssueHDMI Hot-Plugging May FailApalis TK1Graphics, HDMI, I2C, KernelLowNo

Description: While HDMI hot-plugging works just fine on the Apalis Evaluation board it currently fails with EDID errors on Ixora. It's related to a voltage level incompatibility on Ixora with Apalis TK1 modules.

ELB-621Known IssueSPI clock not monotonic across two transfersColibri VF50, Colibri VF61SPILowNo

Description: The SPI clock frequency seems not to be monotonic across transfers (e.g. there is a short clock pulse between two subsequent transfers).

Workaround: Set device tree properties fsl,spi-cs-sck-delay and fsl,spi-sck-cs-delay to 100ns and 50ns respectively in dspi device tree node.

ELB-611Known IssueDistro Boot IntegrationApalis iMX6, Colibri iMX6Bootloader, SDIO/SD/MMC, USBLowNo

Description: At least Fedora 25 for ARM currently just hangs upon booting the kernel without any further messages being printed.

ELB-602Known IssueColibri T30 May Freeze on Concurrent SD Card and Multiple USB Devices Stress TestingColibri T20, Colibri T30, Apalis T30SDIO/SD/MMC, USBLowNo

Description: In use cases involving all 3 USB host controllers with USB hubs connected to the OTG as well as the regular host port with USB keyboard/mouse resp. USB-to-serial-adapter connected plus an SD card the Colibri T30 may freeze upon stress testing.

Workaround: Only use two USB host controllers. Ethernet already uses one of them. Use an external USB hub for further USB ports.
Alternatively if you don't use Ethernet you may disable it as follows: 'echo 0 > /sys/class/gpio/gpio232/value'.
We didn't see these issues when using mainline.

ELB-587Feature RequestSupport SD UHS mode (new feature of Colibri iMX6 V1.1)Colibri iMX6SDIO/SD/MMCLowNo

Description: Add support for SD UHS (1.8V) which is possible with V1.1 of the Colibri iMX6.

Workaround: The following commit for BSP 2.6 introduces an optional SD_1_8 define for enabling UHS-I support:
http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_imx_3.14.52_1.1.0_ga&id=7659fe414d37861050ec909bb2d27c4bfca87d27
Please note that all Toradex carrier boards by default use 3.3 volt pull-up resistors on resp. signal pins which would need removing as well.

ELB-575Known IssueLX Panel, CPU Usage Monitor & Confusing Display Due to Dynamic Full ScaleApalis TK1, Colibri T30, Apalis T30CPULowNo

Description: The LX Panel gives an overview of the current CPU Usage by providing a rolling chart of the last minute. Full Scale of the chart is what all the CPU cores which are currently on could compute at the current CPU speed. Since the CPU speed adapts to the current workload full scale is not a constant. On top of that on some modules CPU cores are dynamically switched on or off depending on the current computing load. This can lead to the confusing effect that increasing the load by a little can lead to a decreased load displayed in the 'CPU Usage Monitor' because on additional core is switched on.

ELB-571Known IssueMemory Corruption with ext4 FilesystemColibri T20, Colibri T30, Apalis T30Flash, Kernel, SATA, SDIO/SD/MMC, USBMediumNo

Description: NVIDIA's downstream L4T kernel our BSPs are based on has issues with the ext4 file system.

Workaround: Use the ext3 file system instead.

ELB-566Known IssueGPIO interrupts do not work on Cortex-M4 after Linux bootColibri iMX7GPIOLowNo

Description: If a GPIO bank is assigned to Linux (defined in the device tree), the driver masks and clears all GPIO interrupts on startup. If a GPIO of the same bank is used as a interrupt source on the Cortex-M4 core, the interrupts will not work after Linux started. If the M4 enables an interrupt after Linux started, Linux will receive that interrupt too and mask the interrupt again (since from a Linux perspective, the interrupt is not enabled).

Workaround: Disable a GPIO bank in the device tree to assign it exclusively to the Cortex-M4 core.

ELB-560Feature RequestU-Boot SPL Does Not Go to Recovery Mode If No Bootloader Is FoundApalis iMX6, Colibri iMX6BootloaderLowNo

Description: If the SPL can't load the bootloader it currently prints a message and hangs. Change that to print a message and start in Recovery Mode, aka. Serial Download Mode.

Workaround: Go manually into Recovery Mode. Refer to the modules data sheet for possible procedures.

ELB-557Known IssueImplement workaround for unstable 500MHz clock errata (e6235)Colibri VF61CPULowNo

Description: Due to a chip errata the main CPU clock may be unstable. During our extensive testing We have not observed issues with our design so far. We never saw any problem and also don't have any negative customer feedback.

ELB-554Known IssueExar PCIe UART driver does not work on Apalis T30Apalis TK1, Apalis T30PCIe, UARTLowNo

Description: Exar PCIe UART driver backport (or official Exar driver) does not work on Apalis T30

ELB-550Known IssueI2C6 on Apalis TK1Apalis TK1I2CLowNo

Description: I2C6 as available on Apalis TK1 MXM3 pins 71/73 aka DP_AUX_CH0_N/P is currently not supported.

ELB-542Feature RequestARM DS MDK Linux Kernel DebuggingColibri iMX7Buildsystem, Miscellaneous PeripheralsLowNo

Description: ARM DS MDK requires a special set of Linux kernel configuration options in order to allow for debugging the Linux kernel (incl. modules) and FreeRTOS side by side. Unfortunately some of those required configurations are unsuitable for our regular BSP plus one anyway needs the full debug symbol for any real debugging.

Workaround: Please enable the following Linux kernel configuration options: CONFIG_DEVKMEM, CONFIG_DEBUG_INFO, CONFIG_PROFILING, CONFIG_FTRACE and CONFIG_ENABLE_DEFAULT_TRACERS. Then disable this option: CONFIG_CPU_IDLE. Now re-compile as explained in the following article on our developer website: http://developer.toradex.com/knowledge-base/build-u-boot-and-linux-kernel-from-source-code

ELB-540Known IssueSome USB Thumb Drives don't Work Well in U-BootApalis iMX6, Colibri iMX6Bootloader, USBLowNo

Description: Use these results in load errors when copying large files, e.g. once used for image update.

Workaround: Find one that works for you. All USB SD card readers we tried so far worked.

ELB-539Known IssueFirst Boot, Rootfs Expansion Affects System PerformanceApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30FlashMediumNo

Description: On first boot the rootfs partition gets expanded to the full size of the partition it lives in. This resizing process adversely affects system performance for the first few minutes until completed. Compare with: http://git.toradex.com/cgit/meta-toradex-bsp-common.git/tree/recipes-core/fs-init

ELB-538Known IssueUSB Hub on Evaluation Board not Enabled in U-BootApalis iMX6Bootloader, USBLowNo

Description: USB hub on Evaluation Board not enabled in U-Boot.

Workaround: Use USBH3 or USBH4 if you need a USB host in U-Boot.

ELB-536Known IssueNo Backlight PWM on V1.0 HWApalis iMX6PWMLowNo

Description: There is no backlight PWM on V1.0 HW. The pin can be used as a backlight GPIO to switch between off and on.

ELB-535Known IssueX11 can only use one ScreenApalis iMX6, Colibri iMX6DSI, Graphics, HDMI, LVDS, RGB, VGALowNo

Description: The Vivante X driver can only make use of the first framebuffer /dev/fb0 while the others can be used through the fbdev framebuffer interface.

ELB-534Known IssueOn some Monitors HDMI EDID is ProblematicApalis iMX6, Colibri iMX6Graphics, HDMILowNo

Description: On some monitors HDMI EDID does not negotiate correct timings.

Workaround: Adding/removing mxc_hdmi.only_cea=1 to the kernel command line may help.

ELB-533Known IssueMic Input not Hot-PluggableApalis iMX6, Colibri iMX6Analog AudioLowNo

Description: Hot-plugging a microphone can reset the audio codec. The driver is not able to bring up the codec again after such an event. This is fixed in Apalis iMX6 V1.1 and will be fixed in Colibri iMX6 V1.2.

Workaround: Not hot-plug the microphone or rebooting fixes the issue. Having a 100 Ohm resistor in series to the microphone on a carrier board makes the module mic hot-pluggable.

ELB-532Known IssueHDA Audio not AvailableApalis iMX6Digital AudioLowNo

Description: The i.MX 6 SoC does not feature HDA audio functionality. Thus the HDA codec on the Apalis Evaluation Board can not be used.

Workaround: If a audio codec needs to be connected you could use I2S and AC97. Refer also to: http://developer.toradex.com/software/linux/linux-software/release-details?view=release-roadmap&&issue=21313

ELB-531Known IssueUART Control Signals DCD/DSR/DTR/RI not workingApalis iMX6, Colibri iMX6UARTLowNo

Description: The UART DCD/DSR/DTR/RI signals are not integrated into the driver.

Workaround: Configure them to be GPIO and read/set them from userspace.

ELB-530Known IssueIrDA not ImplementedColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30IrDALowNo

Description: IrDA requires specially modulated UART signals. While at least some of the UART drivers can be compiled or configured to use IrDA we didn't test if this would actually work.

ELB-529Known IssueU-Boot: USB OTG Port is Always ClientApalis iMX6, Colibri iMX6Bootloader, USBLowNo

Description: In U-Boot the USBO1 and USBC ports for Colibri and Apalis respectively are configured to be client only.

ELB-526Feature RequestSGTL5000 Audio Multi Instance Codec DriverApalis TK1, Colibri T30, Apalis T30Analog AudioLowNo

Description: The SGTL5000 driver in the Linux Kernel currently only supports one codec. The driver would need amending so that multiple codecs can be used. The issue is the statically created VDDD_LDO regulator.

ELB-525Feature RequestAdd support for DSI DisplayApalis iMX6DSI, GraphicsLowNo

Description: The i.MX 6 MIPI DSI interface is available on type specific pins. Setup HW on those pins and bring up the DSI interface.

Workaround: The DSI interface is expected to work, however it has not yet been tested.

ELB-510Known IssueGstreamer Video Playback Segmentation FaultApalis TK1Video CodecsLowNo

Description: While gstreamer video playback works fine it segmentation faults at the very end as follows: Caught SIGSEGV exec gdb failed: No such file or directory Spinning. Please run 'gdb gst-launch-1.0 889' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.

Workaround: Just Ctrl-C the gstreamer process as indicated.

ELB-503Known IssueColibri Evaluation Board: USB 3.0 Devices Plugged in at Boot Time is not AccessibleColibri iMX7USBLowNo

Description: On the Colibri Evaluation Board V3, a USB 3.0 device plugged in at boot time is not accessible after boot. Furthermore, the device seems to influence the on-board USB hub in a way that any USB port 1-4 won't work anymore.

Workaround: Using a regulator in the device tree to toggle the reset of the external USB hub might help avoiding the issue, see https://community.nxp.com/thread/335298.

ELB-496Known IssueTemperature Test on Colibri T20 Uncovered UBI Error When Using bonnie++ With Latest ImageColibri T20FlashMediumNo

Description: Temperature test on Colibri T20 uncovered UBI error when using bonnie++ with latest image.

Workaround: Use stable BSP V2.3 based on YAFFS2.

ELB-487Feature RequestImplementing Linux Serial Driver using K20 UARTsApalis TK1UARTLowNo

Description: K20 MCU has multiple UART peripherals. Special driver integration would allow to use them as serial ports from Linux running on TK1.

ELB-463Known IssueSPDIF not WorkingColibri T20, Colibri T30, Apalis T30Digital AudioLowNo

Description: SPDIF is not working in the V2.6 beta 2 release. This is a regression against older releases.

ELB-458Known IssueConnected SDCard Prevents U-Boot from entering Recovery ModeColibri iMX7, Colibri iMX6Bootloader, SDIO/SD/MMCLowNo

Description: When one wants to enter recovery mode, aka serial download mode, that mode is not correctly working when a SD/MMC card is connected on the SD1 interface, e.g. the SD slot on the Evaluation Board. Symptoms: If the SD card is flashed with an U-Boot the module does not enter recovery mode at all but tries to load said U-Boot. On i.MX6, even if the SD card is not flashed with U-Boot the module does fail when downloading DCD data over USB.

Workaround: Remove any SD card from your system during power cycle / reset when you intend to enter recovery mode.

ELB-452Known IssueUSB OTG on Aster, Orchid, Viola Need USB_P_EN# for Host RoleColibri iMX7, Colibri iMX6, Colibri VF50, Colibri VF61, Colibri T20, Colibri T30USBLowNo

Description: On Aster, Orchid and Viola the USB power enable pin (SODIMM 129) is used for both USB ports USBC and USBH. For all modules but the Colibri iMX7S the Linux kernel controls the USB Power Enable only from the USBH port driver. Thus USBC will be non functional if used as a USB Host when the USBH port is disabled in the kernel (i.e. in the device tree for newer or in the platform data for older kernels). Note that on the Evaluation Board and on Iris the USB Power gets enabled when a USB OTG kabel gets connected.

Workaround: Do not disable the USBH port or change the kernel in a way that the USB Power Enable is controlled by the USBC port as well.

ELB-433Known IssueSuspend/Resume does not Work with PCIeApalis iMX6PCIe, Power ManagementLowNo

Description: Suspend/Resume does not work if a PCIe device has been found. e.g. if 'lspci' returns at least one device. Symptom is that resume blocks after all CPUs have been brought up.

ELB-419Feature RequestLVDS Channel ConfigurationApalis iMX6LVDSLowNo

Description: Starting with Apalis_iMX6_LinuxImageV2.6Beta2 the display timings and resolution can be set from the kernel command line or from the device tree. However the LVDS channel configuration can only be set from the device tree. Implement a command line parameter to bring back this functionality similar to the ldb=xxx parameter from the 3.10.17 kernel. Single/Dual channel. Colour Depth and mapping.

Workaround: Change the device tree according to the needed LVDS configuration.

ELB-408Known IssueUART Overruns When Using DMAApalis iMX6, Colibri iMX6UARTLowNo

Description: The UART may overrun when using DMA. We were not able to reproduce this issue which was reported by a customer.

ELB-407Known IssueBusybox and UTF-8 Chars in FilenamesColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: For many utils (e.g. ls) we use busybox in our image. These utils in the used busybox version display chars outside of the 7 bit ASCII range as a '?' even if the locale is set correctly and the system uses e.g. UTF-8.

Workaround: Just enable UNICODE in the BusyBox configuration and re-compile.

ELB-399Known IssueGstreamer/Nvgstplayer Memory LeakColibri T30, Apalis T30Multimedia, Video CodecsLowNo

Description: Each iteration of a movie H264 playback using gstreamer/nvgstplayer allocates a queue via NvMMQueueCreate(phQueue=0x4225f318, max_entries=32, entry-size=224, thread_safe=1) inside NVIDIA's binary only libnvmm_utils.so library which is never freed (such a function creates three pointers of total size 7392 + 28 + 32). Most probably there is a missing NvMMQueueDestroy() somewhere in the decoder handling.

Workaround: The easiest workaround would be to spawn a new gstreamer process for every movie being played as destroying that process after the playback will explicitly free any memory even if not previously implicitly having been freed. Alternatively our partner Antmicro hacked up a custom libnvmm_utils.so wrapper library to be loaded by LD_PRELOAD which may intercept NvMMQueueCreate() calls and adaptively revert to a static queue in order to prevent any memory leaks. While such a solution will of course be highly use-case dependant it should fully fix any leaking. Further investigation on NVIDIA's side is pending.

ELB-392Feature Requesti.MX 6 Thermal ThrottlingApalis iMX6, Colibri iMX6CPU, Temperature SensorLowNo

Description: When the measured SOC temperature reaches /sys/devices/virtual/thermal/thermal_zone0/trip_point_0_temp (currently set to 85°C) the GPU frequency is reduced to 1/64 of its normal value. Once the SOC cooled down to 75°C the clock is set back to 64/64. Should the temperature reach trip_point_1_temp (105°C) the OS is shut down. - Implement a gradual reduction of GPU performance when trip_point_0_temp is reached. - Increase trip_point_0_temp for Industrial Graded products.

Workaround: Set the GPU clock for higher temperatures to something higher than 1/64 in /sys/bus/platform/drivers/galcore/gpu3DMinClock for a trade off of higher performance vs. lower power dissipation.

ELB-386Feature RequestUse Ethernet PHY Power Down Mode for Suspend ModeColibri VF50, Colibri VF61EthernetLowNo

Description: With #16470 the Ethernet PHY power down mode has been disabled. This increased the power consumption during suspend. Since Ethernet is often not used on power constrained devices, we prefer lower power consumption over working Ethernet. Therefor we should reenable the PHY power down mode when using suspend.

Workaround: Use U-Boot's MII capability to put the PHY into sleep mode at boot time (use "mii write 0 0 0x3800" to set PHY's PDOWN mode).

ELB-367Known IssueRare Kernel Panic While Using RNDIS USB GadgetColibri VF50, Colibri VF61USBLowNo

Description: In USB device mode using RNDIS on Vybrid with Windows as host might result in a kernel crash during continuous bi-directional data transfer.

ELB-338Feature RequestLinux Kernel Splash Screen Doesn't Work on HDMI OutputApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T20, Colibri T30, Apalis T30HDMILowNo

Description: Using a Linux logo be it the penguins or a custom one as e.g. explained at http://developer.toradex.com/knowledge-base/splash-screen-linux does not work on the HDMI output. When the kernel sets up the display driver it first sets up VGA resolution subsequently doing DDC/EDID and then sets the final resolution. While the Logo is drawn during the VGA resolution setting it is lost later on.

Workaround: On Apalis/Colibri iMX6 one may use the U-Boot splash screen on HDMI output as well.

ELB-328Known IssueHDMI Violation on 720x480p 16:9Apalis iMX6, Colibri iMX6HDMILowNo

Description: At 720x480p resolution the 'AVI Information Frame' might inadvertently report an aspect ratio of 4:3 even though 16:9 is in effect.

ELB-314Feature RequesteCos Freeze/MCC LockupColibri VF61CPU, KernelLowNo

Description: eCos freezes or deadlocks after running MCC pingpong for some time.

ELB-313Known IssueIncompatibility Between L4T Linux Kernel and iproute2-ss140804Colibri T20, Colibri T30, Apalis T30CANLowNo

Description: There exists an incompatibility of sorts between the older L4T Linux kernel version our Tegra BSPs are based on and the newer iproute2-ss140804 from our V2.4 BSPs leading to errors as follows:
