WEC iMX6 BSP Release

Description: Under some circumstances (mostly saving passwords or WifFi connections) a "FlashDisk" folder is created at boot and the internal storage is mounted as "FlashDisk2". This is because some System Services that rely on the internal flash to be mounted are not waiting for it to be and then create a \Flashdisk folder. This is fixed by adding dependencies on CmService and CredSvc

Description: This IOCTL is used by ConfigBlockEditor Tool to delete a Config Entry. This was not supported so far.

Description: Added IOCTL_EMMC_BUSREQUEST and IOCTL_EMMC_INFOQUERY IOCTLs to sdmem driver. This is mainly used in MMCTool for getting information and doing eMMC firmware update and patches.

Description: Updated Update Tool to latest version (8.3.0)

Description: When transitioning from Splashscreen to Windows Desktop, the Display controller was re-initialized and this could cause glitched in the clock which can lead to issues (jittering in the desktop display picture) with some displays (especially LVDS displays).
This fixes it by not re-initializing the display controller if the useSplashScreen setting is set (same SplashScreen settings will also be kept in windows desktop mode)

Description: Normally we mute DAC after Playback is done to minimize Audio Noise. But if this behavior is not wished it can be changed with:
\[HKEY_LOCAL_MACHINE\\Drivers\\Builtin\\Audio]
"AutoMuteDAC"=dword:0

Description: On new Apalis iMX6 Modules we were forced to replace the current Ethernet Phy (KSZ9031RNX) since is not available anymore. This update is needed to support new HW with the new KSZ9131RNX Ethernet Phy Chip.

Description: LVDS display does not show splash screen

Description: Report deleted filesystem blocks to the eMMC controller using the TRIM command. This improves write performance and efficiency of wear-leveling. This feature can be disabled by setting: [HKEY_LOCAL_MACHINE\Drivers\SDCARD\ClientDrivers\Class\MMC_Class\High_Capacity] EnableTrim=dword:0

Description: RAM table is not initialized correctly in this release and devices are limited to less than 100MB of memory even if more physical ram is available.

Workaround: Relase 1.5b4 fixes the issue.

Description: Calling CloseHandle on and handle for COM2:, COM3: etc. (all internal UARTS) will turn off the UART master clock, disabling also COM1: (UARTA) even if it's still in use.

Workaround: Keep a handle to an internal COM port open even if you are not actively using it. Issue will be fixed in version 1.5b2.

Description: Added missing .bat file associations

Description: The registry can be write-protected by a setting in the bootloader config block (dbg.regwrite=0). This setting is ignored by the OS, the registry can be written anyway.

Description: The compression tool provided with 1.4b4 release of the BSP may generate an invalid image if no splashcreen is provided.

Workaround: Issue will be fixed in 1.4 release, in the meantime an updated version of the tool can be downloaded here: https://docs.toradex.cn/104689-imagecompressiontool-imx6.zip

Description: By default the BSP relies on an external RTC, but it's possible to enable usage of the internal RTC in config block settings. https://developer.toradex.com/internal-rtc-ce

Description: Since 1.4b4 by default, the image uses the screen configuration configured in the ss parameters of config block settings. This can be changed by setting the UseSplashSettings parameter to 0, as documented in the display driver configuration page on the developer center. If ss.out was set to 0 (VGA) on Apalis you may have an unstable image or no picture at all as soon as the OS starts.

Workaround: The issue has been fixed in 1.4 release.

Description: Due to a clock misconfiguration, audio playback is 10% slower than expected and this impacts also the pitch.

Workaround: The issue has been fixed in release 1.4b4

Description: - Added 936 (Simplified Chinese), 949 (Korean), 950 (Traditional Chinese) - Removed all Locales except English US (they can be re-added with cab installers) Cab installers can be found here ( https://developer.toradex.com/add-locales-to-an-existing-windows-embedded-compact-image )

Workaround: The issue has been fixed in release 1.4b4

Description: Building binary image fails with errors MSB3073: The command "romimage" and fails to find files _filesys.dll and registry.fdf

Workaround: The issue has been fixed on release 1.4b4, on release 1.4b2 to fix this issue rename file \TORADEXIMX6BIN\Files\TORADEXIMX6-preri.bat to \TORADEXIMX6BIN\Files\TORADEXIMX6BIN-preri.bat

Description: Resetting the system while playing audio can render the audio system to be silent until another reboot.

Description: Restoring the filesystem from update tool may damage the registry or the os image.

Workaround: Filesystem may be restored using the autocopy feature. Issue has been fixed in the update tool release that is provided with 1.4b4 images.

Description: Adding new bootloader command to enter recovery mode: "reboot rcm"

Workaround: Issue has been fixed in version 1.4b4, supporting "reboot rcm" command, on older releases you can use two bootloader commands:
bootfrom usb
reboot

Description: Removing the backlight driver in Platform Builder leads to wrong interpretation of the platform.bib file.

Workaround: Issue has been fixed in version 1.4b4 and new catalog file makes management of BSP features simpler.

Description: Memory for the main framebuffers must be allocated in video memory, if not enough memory is available, the display driver cannot be loaded. Application can request further memory, if that is not available the driver should fallback to regular memory, but a bug prevented that and lead to a crashed display driver.

Workaround: Issue has been fixed in release 1.4b4

Description: Since the compressed format is the only one supported by the easy installer we decided to release the tool for free. It is part of binary BSP and the new sample OS Designs will build nbx file by default (bin is still built to be used for debugging etc.).

Description: AC97 tweak tool works now also with iMX6 modules: https://developer.toradex.com/knowledge-base/ac97-tweak

Description: When a short audio sample (less than one second) is played it is barely audible. Longer samples seem to not have this issue. This is due to the fact that the audio driver turns volume to zero when no sound is played and then increases it back to previous level when starting playback of a new sound. The volume by default is not increased immediately (to prevent popping sounds or noise) and this may lead to short sound played after at least 2 seconds without any sound played being barely audible.

Workaround: Remove slow volume ramp-up by adding registry entry: [HKLM\builtin\Audio] "Reg0x0E"=dword:03000000

Description: Details about this feature can be found here: http://developer.toradex.com/knowledge-base/debug-message-buffer

Description: Using some resistive touch panels the touch does not behave correctly. Touches are not detected correctly or dragging is stopped even if the stylus/finger is still touching the screen.

Description: When multi-monitor mode is enabled and the screens have a different setting for the BPP parameter (ex: the main screen is 32BPP and secondary is 16BPP) then GWES.DLL generates an exception and both screens will remain black). This does not happen when clone mode is configured.

Workaround: Configure same BPP for all the displays involved in a multi-monitor configuration.

Description: The DC level for outgoing audio signals is too low. This has no impact if audio is played on low to medium level, but at high volume, this leads to audio distortion.

Description: Displays using specific pixel clock frequencies will not work on 1.3 release due to an issue with enabling/disabling of PFD0 of 528MHz PLL. Displays that are driven using PLL5 (VIDEO PLL) work.

Description: Resistive Touch presses are not properly detected.

Workaround: Changing the value of STMPE811_Min_Pressure may improve behaviour on some touch screen models.

Description: Toradex Easy Installer image for Windows CE will now clean config block, restoring default configuration.

Description: When certain timezones are selected (e.g.: UTC+9:00 Osaka, Sapporo, Tokio) the page allowing to set time on the RemoteAdmin interface does not work.

Workaround: Change the timezone prior to using RemoteAdmin

Description: When the device is configured to use a static IP and a DNS is also configured sometimes the NTP client (time synchronization) crashes at boot, and this may impact other networking services. This issue was introduces with the Microsoft March 2017 updates.

Workaround: If you don't need NTP client you can disable it by changing the registry configuration.

Description: Simplify usage of tchproxy.dll

Description: The Registry editor does not display certain multilanguage string settings.

Description: Registry format has been changed in release 1.4b2 to improve boot time and to solve issue #28896 (Deleting default registry entries does not work). Unfortunately, it's not possible for the new image to load a copy of registry stored by old releases.

Workaround: You can export registry keys using the registry editor and use the same tool to re-import those changes in new images.

Description: Currently application debugging over USB / RNDIS is not supported out of the box in the debugger client. Add support for RNDISFN to the debugger client.

Description: We added registry settings to default images. [HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\TOUCH] "DriverName"="tchproxy.dll" [HKEY_LOCAL_MACHINE\Drivers\Touch] "Prefix" = "TCH" "Index" = dword:1 "Order" = dword:2 "Flags" = dword:8 ; DEVFLAGS_NAKEDENTRIES "IClass" = multi_sz:"{25121442-08CA-48dd-91CC-BFC9F790027C}", "{7119776D-9F23-4e4e-9D9B-9AE962733770}" "Priority256" = dword:6D ; touch ist priority = 109 "DLL" = "_touch.dll" [HKEY_LOCAL_MACHINE\System\GWE\TouchProxy] "tchcaldll" = "tchcaldll.dll"

Description: Support IOCTL_HAL_CLEAR_REG to allow registry cleaning without using update lib

Description: The text editor starts with a random font selection.

Workaround: Select the font manually in the Format -> Font... menu. Save the registry if you want to change this permanently.

Description: In image 1.3b4 the image format has been changed to reduce boot time. Release 1.4b2 contains additional changes to further reduce this time and allow users to run their own user-mode application as soon as possible. Changes should not impact the operations of most applications, but if your application needs to access some resources immediately at startup you may need to change your code to wait until those are available. In the new image those relevant changes have been made: - reduce timeout/delays of different startup routines: this should not have impact on existing solution, the new delays have been tested and work as the over-conservative delays of previous releases - change to registry format: format is not backward compatible, if you want to import registry from an old version you'll have to export/re-import it using the registry editor app and not update tool - some drivers are loaded asynchronously. This greatly improve image startup time, but some drivers may not be ready when the application starts. Separated items have been added for the above issues, you can find more information there and in the developer website.

Description: Calling reboot via IOCTL sometimes just hangs the system while rebooting. This issue is fixed on Windows Embedded Compact 7 for Colibri and Apalis modules and on WEC 2013 for Apalis modules. The issue can still be seen on Colibri iMX6 on WEC 2013, see issue #34234.

Description: Critical section in ENET driver is not initialized when used the first time. However, it should not have caused any issues as it was only during initialization when everything was running sequentially.

Description: The issue happens only on release 1.3b4 and only if GPU is enabled (enable2d3d parameter is set to 1 in clock driver configuration, that is the default). The device sometimes does not fully boot and the last message on debug UART is "Loading clock driver...". Issue seems to happen more frequently after a software reboot.

Workaround: Issue has been fixed in release 1.3

Description: Through a change in V1.1 of the Colibri iMX6 modules it is possible to assert nReset_Out during a software reset.

Description: Support the CSI camera interface.

Workaround: Use USB cameras or use Apalis T30 which supports CSI.

Description: Implement a feature to disable the data enable (DE) or sync (VSYNC and HSYNC) signals form the display controller in order to use them as GPIOs.

Description: Custom images larger than 100MB will not boot on IMX6 modules.

Workaround: Booting large images works with bootloader 1.3b4, if you use compressed images you need to update the image compression tool to the latest release.

Description: There is an issue mounting the \FlashDisk storage folder that has a 5' timeout. The device takes more than 5' minutes to boot and does not mount \FlashDisk. This happens only on devices where Windows Embedded Compact was not installed or that had their flash memory erased before the installation.

Workaround: There are two workarounds: - Install image version 1.2 instead, boot it and then use update tool to install the new image and bootloader - Wait until the device has booted (5-6') and then use registry editor to add this entry to the device registry: [HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\BootMMC\FATFS] "DisableAutoFormat"=dword:0 Save the registry and reboot, now the device will boot normally and mount \FlashDisk as expected

Description: The current idle implementation is a busy wait concept. We will use a WaitForInterrupt approach instead.

Description: Adapt bootloader output so that is the same as on other module families.

Description: Bootloader is turning on only the minimal set of clocks required to load the image, jtag clock is not enabled and so it's not possible to attach a jtag debugger to debug bootloader/early image boot.

Description: Add support to control the backlight (on-off, no brightness). Backlight timings can be configured in display options inside control panel. Currently the timeout is not configured by default, this keeps the display on all the times, as it was in previous releases.

Description: The format used to store the compressed image has been changed. The new bootloader and updatetool/libraries can use both old and new images, old tools with return an error before flashing it. If you want to update a system running an image earlier that 1.3b4 you need to use the latest updatetool (part of the download package of the new image).

Description: VSDebugger.exe uses the default ethernet devices of the different modules. This new release supports also the VMINI adapter, allowing debugging of OS using Platform Builder and application using Visual Studio debugger. If the device does not use the ethernet interface but has a different kind of connection supporting TCP/IP (wi-fi, modem etc.), adding the CheckAdapterName DWORD parameter under HKLM\SOFTWARE\Toradex\Debugger and setting it to zero will allow the debugger to run without checking the adapter used.

Description: Support the parallel camera interface

Workaround: Use USB cameras or a Colibri T20 or Apalis T30 until the parallel camera interface is supported.

Description: Investigate Use system files from FlashDisk or overwrite to Windows folder while loading Wait4FlashDisk driver.

Description: Add Bluetooth support into the standard image.

Description: The mem config block settings can be used to configure the amount of memory dedicated to IPU and GPU by the OS. Those parameters are swapped, ipumem configures memory for GPU and gpumem memory for IPU.

Description: We harmonized the registry settings for the internal EMMC driver. The settings will be the same on all our platforms.

Description: If flash was written a lot it may happen that initial scan at boot will take more then 60s.

Workaround: Increase the timeout under [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Wait4FlashDisk] "Timeout"=dword:3C

Description: Even when the "HighSpeed" parameter is set to 0, forcing the device to operate in full-speed mode, USB device port still works in high-speed mode, this may prevent the device from being detected or operating reliably on some carrier boards.

Workaround: No workaround available

Description: Ethernet may not be able to reconnect if the connection changes from 10MBits to 100MBits on the router side.

Description: Add SYGEN_FIBER

Description: Write operations can fail when multiple threads are writing on the eMMC/SD on a multi-core system.

Workaround: Issue has been fixed in version 1.2b6

Description: Explorer.exe no longer outputs debug messages

Description: Currently the i.mx6 BSP does not increment idle counters in the right way. GetIdleTime returns almost always 0. This leads to high CPU usage figures in the Colibri Monitor tool

Workaround: Issue has been fixed in release 1.2b4.

Description: Ethernet stops working and a reboot is required to restore its functionality. This seems to happen when inbound and outbound traffic is generated and sometimes leads to a non-responsive device. This issue is seen in special circumstances only. We don't know yet all the details.

Workaround: The issue has been solved in release 1.2b4. A new driver has been integrated and tests that generated freezes of the network stack or the whole system with previous releases now work correctly.

Description: Boot messages from i.MX6 don't clearly specify what driver has been loaded, this may be confusing when trying to debug startup issues.

Workaround: Since version 1.2b4 the output matches the format of other BSP and each loaded driver outputs a message when starting and completing the initialization process.

Description: Allow two displays which cloned content. Displays must support the same resolution.

Description: Add support for the HDMI interface.

Description: Configure Pixel Clock Polarity (pcp) to 1 as default for LVDS

Description: We changed the naming and versioning convention used for our WinCE BSP, image, workspace, etc. in order to use a common approach with other Toradex software.

Description: The StallExecution function may be used to implement sub-millisecond waits inside time-critical routines. On i.mx6 the function does not work in a reliable way and the delay is different from the one specified.

Workaround: Issue has been fixed in release 1.2b4.

Description: Splashscreen output over LVDS doesn't work

Workaround: Issue is fixed in 1.2b4 bootloader.

Description: For some baud rates the actual bit rate is not very precise and this may lead to problems with devices that are not able to auto-adjust their baud rate, mostly when a large amount of data is transferred with no interruptions.

Workaround: Issue has been fixed in release 1.2b4

Description: .

Description: RNDIS driver generates a lot of debug output. Changed build type in order to remove debug output.

Description: We changed the naming and versioning format slightly in order to have a common approach for Linux, WinCE, and other Toradex software packages. Details about the versioning can be found here: https://developer.toradex.com/knowledge-base/toradex-software-versioning-convention

Workaround: Version 1.2b4 uses the new naming

Description: Some of the time servers configured in the standard image are no longer active. We replace the NTP servers with the ones from the NTP Pool Project (See also: http://www.pool.ntp.org )

Workaround: Add additional time servers and remove the non-valid ones as described here: https://msdn.microsoft.com/en-us/library/ms884926.aspx?f=255&MSPPError=-2147217396

Description: Console output is very slow, this seems to affect only console and not the whole graphic subsystem.

Workaround: Issue has been fixed in version 1.2b4

Description: When opening modify window in registry editor, value is automatically focused.

Description: Users are not able to export custom keys from registry.

Workaround: Contact customer support for new registry editor tool.

Description: Using switch /S with registry editor still shows conformation and error windows.

Description: When opening modify window in registry editor, value is automatically focused.

Description: Support the new Apalis iMX6D 1GB IT SKU, product number 0035xxxx.

Description: SPI driver supports also 8 and 16 bits word lengths, but if the total length of the frame is not 32 bit aligned, the first 1,2 or 3 words are not in the correct order or contain invalid data.

Workaround: Issue has been fixed in release 1.1

Description: The remote administration interface is not asking for initial password setup. Issue impacted only release 1.1 beta 4.

Workaround: Issue has been fixed in release 1.1

Description: User can now configure time between re-connection attempts and number of times re-connection will be performed. Instructions can be found here: http://developer.toradex.com/knowledge-base/netui-additional-settings

Workaround: Included in release 1.1

Description: After a software reset devices attached to the host-controller ports are not longer detected.

Workaround: Issue has been fixed in release 1.1

Description: Defining BSP_NODISPLAY will exclude display support from the image, undefining BSP_DISPLAY in the BSP batch file will just exclude the display driver, letting customers replace it with a different one, the NOP driver, for example. This should allow users to connect with the remote display tool even if no display is physically connected to the module. NOP driver still uses some memory for its internal frame buffer.

Workaround: Issue has been fixed in release 1.1

Description: Using the USB serial driver as described here: http://developer.toradex.com/knowledge-base/serial-over-usb The connection is not re-activated if the network cable is unplugged and re-plugged

Workaround: Configure the USB controller to work as client only and not as on-the-go: http://developer.toradex.com/knowledge-base/usb-on-the-go

Description: Even if boot.silent is set the first message "Toradex Bootloader " is displayed on top of the splash screen.

Workaround: Issue has been fixed in bootloader 1.1 beta 4

Description: SD controller 2 has no default pinout on Colibri, so the driver is not loaded by default. Also configuring pinout is not working and currently the driver cannot be used on Colibri modules based on i.MX6. This impact Colibri modules only, SD slot 2 works on Apalis modules.

Workaround: Issue has been fixed in version 1.1 beta 4

Description: When auto-negotiation is disabled in the registry it's impossible to setup 10mbit link.

Description: Issues have been reported with eMMC contents corrupted during file access or after a reboot. One or more sectors are written with incorrect data and this may lead to single file corruption or to corruption of the whole filesystem. Caching may prevent the issue from being noticed until the device is rebooted.

Workaround: Issue has been fixed in version 1.1 beta 4. Power fail safe operation requires that a transaction safe filesystem (TFAT or TexFAT) is used on those mass storage devices.

Description: On multi-core modules the whole system freezes when there is activity on eMMC, USB, SPI or ethernet. The issue seems to be related to cache management, but at the moment there are no workarounds.

Workaround: Issue has been fixed in version 1.1 beta 4

Description: Copy/Paste of files doesn't work in the explorer/desktop on WEC2013.

Workaround: Issue has been fixed in version 1.1 beta 4

Description: To standardize naming across different modules and different releases of the operating system some tool executable names have been changed: - update tool is named update.exe when is part of the image and updatetool.exe when provided as a separate download. Having different names is required otherwise the system will always run the update.exe version from image. - pnotepad.exe in Windows Embedded Compact 7 images has been replaced by notepad.exe that is the same tool we use in Windows Embedded Compact 2013 images.

Workaround: If you need to use pnotepad.exe you can take it from previous releases of the OSDesign and store it in the \flashdisk\system folder. This tool is anyway provided only for Windows Embedded Compact 7

Description: This feature is supported on PXA BSPs and images and was ported to i.mx6.

Workaround: Contact support for further details about this feature.

Description: The calculation of the boot partition size was wrong. This could lead to problems for potential eMMC changes in the future.

Description: New eMMC have different organization of boot/user partitions and this required some modification to the recovery mode loader, bootloader and BSP.

Workaround: No workaround available, rev C modules must use at least release 1.1 beta 4 of the BSP/image.

Description: This feature has been added to version 1.1 beta 4. It's now possible to hide network-related messages by adding the “SuppressPopups” = DWORD:1 under [HKEY_LOCAL_MACHINE\Software\NETUI]

Description: Bootloader in version 1.1 beta 4 multiplexes only tx and rx pins of the serial port used for debug console. This allows other signals of the default UART pinout to be used as GPIOs inside the bootloader. Signals may be multiplexed by the UART driver in Windows CE, to prevent that, additional registry configuration may be required.

Description: Customers reported that Apalis modules don't connect to some 1000Mbps hubs and routers.

Workaround: In version 1.1beta2 some parameters can be used to force the speed and mode of the ethernet controller, bypassing auto-negotiation. The parameters must be saved under HKEY_LOCAL_MACHINE\Comm\ENET1 - SpeedMode (can be 10,100 or 1000) forces connection speed - DuplexMode (can be 0 for half duplex or 1 for full duplex) forces connection mode

Description: It is possible to force the usb on-the-go port to behave only as host or as client by changing some registry entries. Check this knowledge base article for detailed information on this topic: https://developer.toradex.com/knowledge-base/usb-on-the-go

Description: The issue has been fixed in version 1.1 beta 2, as described in our knowledge base: USB 2.0 high-speed (480Mbps)

Description: Added IOCTL (CAN_IOCTL_GET_STATUS) to driver. Users can now ready status registers and get more information about the CAN status. This will also be included in our libraries

Description: Currently, the audio driver uses only the main volume setting on the external audio chip to configure output volume, this leads to a low volume on the headset output used as audio output on the modules. The volume can be increase by setting the "HPVolume" dword value under [HKEY_LOCAL_MACHINE\Drivers\Builtin\Audio] to a value between 0 and 127. with 0 being the highest volume. Increasing this volume above a certain value can lead to distortion on the output, depending on the configuration of the carrier board and speakers, so you may need to do some tests to find the optimal value for your specific setup.

Description: Build of custom images of versions earlier that 1.0 may fail because hive-based registry is no longer enabled and supported, but the PRJ_ENABLE_FSREGHIVE is mistakenly still active in some configurations. Since release 1.0beta5 the system no longer uses hive-based registry and custom os designs must use the RAM based registry component instead.

Description: Check this knowledge base article for detailed information on this topic: https://developer.toradex.com/knowledge-base/usb-on-the-go

Description: When a binary os image (uncompressed bin file) is written using the bootloader or the update tool on a device that was used with 1.0b5 or older images it may happen that the image does not boot or crashes randomly. This happens because just part of the image is correctly loaded in memory.

Workaround: Issue has been fixed in version 1.1 beta 2

Description: Using buffer flipping in DirectDraw leads to artifacts on the screen. Issue has been fixed in 1.1beta2 release.

Description: The GPIO multiplexing option described here: http://developer.toradex.com/knowledge-base/pin-multiplexing-for-drivers does not work in image 1.0 because the GPIOMUX driver is not loaded correctly. Issue has been fixed in version 1.1beta2

Description: The USB OTG port doesn't automatically switch between host and client. This is fixed in V1.1beta2

Description: By configuring the dword parameter "ClockAlwaysOn" under [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\USDHC<1/2/3>] the SD controller will keep the sd clock running even when no command or data transfers are pending. This behaviour is required by some wi-fi adapters.

Description: Update of os image failed or lead to a non-bootable device when the image was flashed taking the input file from eMMC.

Workaround: The issue has been fixed in version 1.1beta2

Description: Splash screen is supported since version 1.1beta2, instructions about configuration parameters can be found here: http://developer.toradex.com/knowledge-base/splash-screen#Splash_Screen_Configblock_Settings

Description: QueryPerformanceCounter doesn't work.

Workaround: Issue has been fixed in 1.0 release

Description: LVDS clocks are not matching the frequency configured in the registry.

Workaround: Issue has been fixed in 1.0 release

Description: Sometimes when connecting a device over RNDIS it would not get recognized.

Workaround: Issue has been fixed in version 1.0

Description: I2C4 (supported only on Colibri) is not working.

Workaround: Issue has been fixed in version 1.0 of the BSP, but it will require also an update to 1.6 release of the Toradex libraries.

Description: SPI driver is part of the 1.0 release, SPI feature is not yet supported in the libraries. Information can be provided to customers that want to access the SPI interface directly using the driver interface, but this implementation is not granted to be supported without changes in future releases and will not be compatible with other modules.

Description: Serial driver is not loaded by default for UARTD and E, that are not part of the standard Colibri/Apalis pinout. Those drivers can be loaded by adding the correct entries inside the registry, but their pins must be multiplexed in the correct way in the registry (see documentation on developer's webiste about this).

Description: Configuring a clock of less than 22Mhz for parallel display output does not work, it leads to a wrong frequency and corrupted output on the display.

Workaround: This has been fixed in 1.0beta6

Description: State of the SO-DIMM or MXM3 pins (depending on module's form factor) can be configured using the set pin command in the bootloader console. The pin state must be saved using the save pin command and we be applied on next boot. To let the bootloader change the state of the pin the ctrl field of the corresponding pin must be set to one. For example: set pin.135.ctrl 1 will enable configuration of SO-DIMM pin 135 on a Colibri imx6DL. Other fields that can be configured are: direction level pull strenght outmode

Description: If the "clear registry" option has been used then saving the registry may not work.

Workaround: This issue has been fixed in version 1.0beta6

Description: V1.0 contains all changes up to V1.0beta4: http://developer.toradex.com/software-resources/arm-family/windows-ce/imx/release-details?view=release-notes&version=V1.0beta4

Description: Issue is fixed in 1.0beta6 release

Description: In order to be in sync with Tegra, Vybrid and PXA module family we update the components being included in to the image.

Description: Allow to use one core only on the multi-core iMX6 processors. This might help to determine if application have multi-core problems.

Description: Images from version 1.0beta6 and newer are provided in a compressed nbx format.

Description: Resistive touch is supported in version 1.0beta5

Description: Transferring big files over SMB generates an overrun condition in the ENET controller's FIFOs and then a crash in the driver.

Workaround: Issue has been fixed in 1.0beta5

Description: Display rotation is not working in 1.0beta4

Workaround: Issue has been fixed in 1.0beta5

Description: The RTC is clocked by the 32.768KHz clock. The OAL code rounded ticks to seconds before returning the value to the OS. This issue has been fixed in version 1.0b4 and now the value returned to the OS is rounded to 1/32768th of a second, filling also milliseconds field.

Description: Support for USB-on-the-go has been added in version 1.0 beta 4. This works on Colibri and Apalis and allow usage of the dedicated pins for host or client role.

Description: Depending on the baud rate selected, the actual baud rate might be slightly off.

Workaround: Issue has been fixed in version 1.0 beta 4

Description: UART A can be used as a regular serial port by setting dbg.serial to 0 in the bootloader.

Description: Tx and Rx pins are exchanged on UART C. This SW issue has been fixed.

Description: Add support for the LVDS interface.

Description: The bootloader stopped during the first steps of boot on Apalis i.MX6 2GB IT modules, this prevented installation of the Windows Embedded Compact image on the module.

Description: Add support for UART. UART A is not available in the OS, it's used as debug port. This will be changed in one of our next releases.

Description: Add support for USB host ports.

Description: Add basic support for RGB and VGA displays.

Description: Add basic CAN support through a CAN driver.

Description: Function CeGetVolumeInfo does not report flag CE_VOLUME_TRANSACTION_SAFE for FAT32 formated disk. This is an issue in the Microsoft part.

Description: The Ethernet driver only uses standard Ethernet packets of around 1.5KB, bigger frames are currently not supported in the driver. The hardware would limit the frame size to 8kb.

Description: The update tool may need to lock the eMMC device during some kind of updates (SPL, bootloader, configblock, registry, splash screen), this may generate an issue if the source file used to read the new image is stored on the eMMC (under \FlashDisk in the Windows CE filesystem).

Workaround: Copy the update file to a different folder (root if it can fit in available RAM) or keep it on removable media during the update.

Description: If multiple transfers are aborted in a short time on a multi-core device further transfer to the same endpoint are not executed by the host controller.

Workaround: Invoking a reset of the pipe is required to re-enable transfers after an abort.

Description: With current clock settings the frequencies generated for I2C bus at 100KHz and 400KHz are up to 16% lower than the standard ones, this is due to limited range of dividers available and should not impact operations of connected devices.

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 solves the problem. All Apalis and Colibri iMX6 modules which are in Volume Production state already have the right fusing and configurations. For older modules you may apply this fix this by first migrating your module to Embedded Linux, then proceeding as described in the following article on our developer website after which you may migrate back to WinCE/WEC again: http://developer.toradex.com/software-resources/arm-family/linux/linux-booting#eMMC_Fast_Boot_Mode_ApalisColibri_iMX6

Description: Cursor blinks while running OpenGL demo application

Workaround: Application can hide the mouse cursor, especially when using full-screen.

Description: When a baud rate is configured using the driver IOCTL interface or using Toradex library the clock frequency is 10-15% lower than the frequency that has been configured.

Description: When using a console under WEC2013 there seem to be a memory leak somewhere.

Description: When using GPIO library setting "none" as value for the irqtrig parameters an invalid parameter error is returned. It's not possible to disable an interrupt in this way.

Workaround: Don't set trigger to "none", but keep interrupt disabled if you don't want it to be generated.

Description: When the device is reset using the update tool "cold boot" option or invoking one of the windows CE APIs that can generate a reboot (SetSystemPowerState or KernelIoControl) USB devices may not behave correctly and need to be unplugged and plugged back again to be correctly detected. This does not happen after a hardware reset.

Description: The "Lease Expires" date is always set to 1/1/1970 initially. This seems to be WEC7 related issue. This is not an issue on CE6.

Workaround: Do a ip renew (ipconfig /release, ipconfig /renew) to get a correct "Lease Expires" date. If you build your own Image, you can also use a legacy dhcp.dll. Get a dhcp.dll which was build with an MS update level before November 2014, there this was not an issue.

Description: Applications that use the Windows CE console to output text may run slower on version 1.4 compared to version 1.3.

Description: Currently the IRDA interface expects standard IRDA signals that use for zeroes a pulse that is 3/16 of one bit length. IRDA devices may operate with shorter pulses (down to 1.41us) but this is not currently handled by the driver.

Description: Unwanted silent periods when playing audio files.

Description: Update Tool Backup and Restore problems when .NET CF is installed.

Description: To save power when the system is not used, not only the backlight should be turned off, but the display controller should be halted, too.

Description: The function to abort a playing sound returns only after about two seconds.

Description: Some openGL applications seem to have issues running on 1.4 release, issue is still under investigation.

Workaround: Customers building their image from the binary BSP could revert to previous implementation by replacing the following files: k_libGAL.dll libCLC.dll libEGL.dll libGAL.dll libGALCore.dll libGLESv1_CL.dll libGLESv1_CM.dll libGLESv2.dll libGLES_CL.dll libGLES_CM.dll libGLSLC.dll libOpenCL.dll libOpenVG.dll libVDK.dll

Description: Add an option to DVFS management to shut down the device if the measured temperature exceeds a certain threshold.

Description: Due to asynchronous driver loading feature added in BSP/image 1.4 some non-standard drivers might have problems due to resources not being ready at the right time.

Workaround: Disable asynchronous driver loading: https://developer.toradex.com/knowledge-base/busenum2#disabling-asynchronous-driver-loading In this article there are also more information about the topic and more sophisticated workarounds using named events to control the loading process.

Description: Issue was identified as problem with Microsoft code. As WEC7 and WEC2013 are in extended support ( https://support.microsoft.com/en-us/lifecycle/search?alpha=Windows%20Embedded%20Compact%202013 ) this is not going to be fixed by Microsoft updates.

Description: Hardware video decoding isn't implemented for iMX6 WinCE platforms.

Workaround: Use software decoding. Optimize the videos to the right resolution and quality to get best results with playback.

Description: Desktop icons reappear after reboot even if relevant registry entries are edited.[HKEY_LOCAL_MACHINE\Explorer\Desktop] registry entries are not persistent.

Workaround: Disable Explorer:http://developer.toradex.com/knowledge-base/disable-and-enable-the-explorer. Delay screen initialization for smooth transition Splashscreen->Application: [HKEY_LOCAL_MACHINE\Drivers\Display\Colibri] "FirstRefreshDelay"=dword:100 ; Delay of 1st refresh in ms.

Description: Add an option to the restorefactoryinfo command to retrieve data from barcode which makes it easier to configure a module with the right serial number and product ID in the config block.

Description: Iperf test hangs for ublox wifi driver(SDIO8787)

Workaround: Set below registry [HKEY_LOCAL_MACHINE\Drivers\Builtin\SDBusDriver] "ThreadPriority"=dword:64 [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\USDHC1] "DisableDMA"=dword:1 "SDIOPriority"=dword:61

Description: Allow disabling the cursor at runtime using ExtEscape functions.

Workaround: Permanently disabling the cursor in the registry is supported. Disabling the cursor for single applications also works with the default OS API (ShowCursor())

Description: A missing or corrupt partition table will lead to non booting modules after the second boot because the OS image gets overwritten by the file system.

Workaround: Create a correct partition table using either the Toradex Easy Installer which does it automatically, or the preparefs command in eboot.

Description: Long AttachDelays might be required to assure that all USB devices are recognized.

Description: Currently, initialization of this driver may take 1 to 1.5 seconds, disabling it if you don't use the OTG port will reduce boot time.

Description: "Start Debugger Client" Does Not Start in WEC2013

Workaround: Open a WinCe command line, type the two commands: start conmanclient3.exe cmaccept3.exe

Description: Display clock is not stopped when back-light is turned off so HDMI or VGA might continue to display content. However, displays using the back-light signal to turn off, e.g. normal LCD displays turn off.

Description: Currently update tool supports: - restore image (compressed or bin file) - restore bootloader - save and restore config block - clearing registry - save and restore registry The tool currently does not support operations on filesystem and does not allow backup/restore of multiple regions at the same time.

Workaround: In combination with the Toradex Easy Installer the AutoCopy feature can be used to store data on the FlashDisk after flashing the bootloader, image, etc.

Description: Implement Suspend and Resume feature.

Description: System sounds are not available under WEC2013.

Description: Large splash screen cannot be programmed with the UpdateTool

Description: EDID reading cannot be disabled for HDMI displays

Description: Changing audio codec registers by registry is supported, but not documented

Workaround: Use the settings as they are documented for PXA and T20/T30 modules.
