WEC T20 / T30 BSP Release

Description: This is a CE8 Image release only, no changes in BSP functionality and Bootloader, only Microsoft System updated were added

Description: When Opening / Closing multiple serial ports many times it can happen that only one COM port can be opened at once.
This problems only happens on T20 as we have GPIO emulated DCD and DSR lines on COM1 by default. But it could also happen on T30 if configured so.

Description: NvFlash 2.7 is now able to Flash SecureBoot enabled devices and a Fusing Tool is available.
This enables protecting Devices so that only signed Software can be booted.
Please contact Toradex Support for more information.

Description: Ethernet Ping times can get very slow. Whole Ethernet communication can sometimes fail due to a race condition in the AX88772B Ethernet driver. Much more likely on T30 (4 cores)

Description: Include additional files into our image, which are required to access smart cards

Workaround: All components are included in WEC7.

Description: The stable release 2.3 contains all changes up to version 2.3b2

Description: Due to a rare race condition sometimes a SDIO card interrupt is not signaled to the card driver and in the case of SDIO8787 WiFi driver could cause a complete network stack freeze.

Description: The bootloader checks the CRC of a WinCE image and provides various options to proceed if a wring CRC is found. By default CRC is checked but on failure only a warning is output and system will try to boot anyway. The behavior can be changed by setting boot.imgcrcaction to 1 (Halt system boot on CRC errors) or to 2 (try booting another image partition)

Description: Comparing 0L and 0L in .NET Compact Framework 3.9 leads to wrong result.

Workaround: You can find a workaround from Microsoft here https://social.msdn.microsoft.com/Forums/en-US/a187a5da-d46f-440c-9e40-e201636c042d/bug-in-net-cf-justintimecompiler-with-roslyn-generated-ilcode-windows-embedded-compact-2013?forum=netfxcompact

Description: When resigning a windowed OpenGL application multiple times the application might close unexpectedly with a data abort error.

Description: There was a problem with initializing Kernel Debugger: Interlock Function were not working properly and system was hanging.

Description: 'set gpio' displays an empty string when called more than once.

Workaround: after entering the command 'set gpio', reset the system before continuing.

Description: Memory was not properly unmapped from User space following a call to NvRmMemUnMap(), thus creating memory leaks.

Description: The stable release 2.2 contains all changes up to version 2.2b4

Description: WPA2 802.1x WiFi Profile is persisted across reboots, but User Credential are asked again each time. This seems to be a MS related BUG in the Connection Manager. We implemented a patch that can be activated by setting the following registry settings: [HKEY_LOCAL_MACHINE\Software\Toradex\FileSystemFilter] "WLAN_Patch"=dword:1 [HKEY_LOCAL_MACHINE\System\StorageManager\Filters\fsdspy] "Dll"="fsdspy.dll"

Description: MultiByteToWideChar() not working anymore for simplified chinese. Codepages 936 (Simplified Chinese) and 949 (Korean) were missing.

Workaround: The image has to be re-built with additional codepages: 936 (Simplified Chinese) and 949 (Korean) in the OSDesign file nlscpg.txt (c:\Wince700\OSDesigns\ColibriTegra_Core\ToradexFiles\Misc\CE7\nlscpg.txt).

Description: Updated the output of Module Name and serial number while booting the device, in order to unify this between all the module families.

Description: The EarlyAutoCopy feature of WaitForFlashDisk driver does not always work.

Description: Since most of the tools flush both HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER, to reduce flush overhead the system ignores flushes on HKEY_CURRENT_USER. This is not the expected behaviour.

Workaround: Call RegFlushKey(HKEY_LOCAL_MACHINE)

Description: So far only CableDetectPin (which needs to be connected to VBUS) could be defined to detect the presence of USB Function or USB Host. Now if "UseIDPin"=1 you can define "IDPin" and "IDPol" and you can have 3 states: No driver loaded, USB Function driver loaded or USB Host driver loaded

Description: On WEC7 and WEC2013 there is no way to open NETUI using code. We fixed NETUI by naming a window. Users can now use HWND handle = FindWindow(NULL, L"NETRTWLANU1”); PostMessage(handle, WM_WZCSYSTRAYICON, 1, WM_LBUTTONDBCLK); To get handle to a window and send message. Window name depends on network interface name.

Description: SDBUS patch needed in order to support both WiFi and BT functions on the SDIO8787 card.

Description: DFS (Dynamic Frequency Switching) on DDR RAM is not supported on Apalis T30 and Colibri T30 modules.

Description: Bootloader GPIO Setting (gpio.bootconfig) fails to set pull state of some GPIOs

Workaround: -

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: 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: If you applied a backup of a config block (CFG) it happened that the serial number / MAC address and hardware ID got lost. This did not happen if you applied a backup by using the CFG file but only if only the config block was restored. This issue was fixed in Update Tool 6.0.15 which is part of this image.

Description: All BSP Features (Drivers, Multimedia, OpenGL, Video, Tools) can be now selected via PlatformBuilder Catalog. No need to edit nvap.bat anymore. This also means that a new Workspace file (defining all standard Features) is needed for customers that build their own Image form the BSP using PlatformBuilder.

Description: The dynamic CPU disabling was introduced earlier but not enabled by default. This will be enabled with this release.

Description: Microsoft fixed issue when NTP server crashed services. This removes the patch we created. If you build your own image please also synchronize with the new workspace.

Description: The Key Default Value (the value assigned to the Key, shown as "(default)") cannot be edited

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

Description: If Update Tool is running under image 1.4 and older and there is no folder "Images" on the USB or SD drive the backup and update file dialogue will not be shown.

Workaround: Add a folder "Images" in the root directory of the USB or SD drive.

Description: In the previous release 2.1b4 the debugger is not working. While debugging you get an error message: “Unable to import library VSDebugEng.dll ! Program will exit.”

Workaround: Copy webservices.dll manually to the target folder \Flashdisk\System\ .

Description: Add Bluetooth support into the standard image. The required DLLs can be added with a flash installer.

Description: If customers use Bluetooth audio it could happen that the analog audio output does not work any longer or also the bluetooth audio stops working.

Description: Added Update Tool 6.0.12

Description: Allow reading of config block parameters from static and/or dynamic config block. If critical data gets lost (MAC or Hardware information) in the config block, this increases the chance it can be recovered, also it got overwritten by the user.

Description: If system idle time is set the backlight / display gets disabled and enabled immediately again after that. Enabling / disabling continues until the next user activity.

Workaround: This issue is caused by the resistive touch driver. Disable the touch controller ([HKLM\Hardware\Touch]).

Description: This feature was not enabled by default in previous images. RAM DFS will be enabeled from now on. It can be disabled by setting the registry key [HKLM\Drivers\BuiltIn\nvrm] DfsEMCLowCornerKHz to 330000.

Description: Device does not boot if it is reset while a I2C transaction is going on on the internal I2C bus. This can potentially happen during DFS activity, Touch interaction, Temperature read out or Audio codec access

Description: Fixed issue that UpdateTool does not show a dialog for Hive Based registry images when doing a backup. This is an issue for Toradex images before V2.0.

Workaround:

Description: The out buffer for IOCTL_HAL_GET_RANDOM_SEED Test must not be larger than 1024. Added check.

Description: On some modules the backlight PWM needs to be modified otherwise the display will keep black.

Workaround: In order to get this working, you can set the ss.bl_gpio = 12 and ss.bl_pol=0. You find all the configs also here: http://developer.toradex.com/knowledge-base/installing-edt-display#Brightness

Description: In some rare cases the internal I2C bus can be blocked. This results in the fact, that Touch and Audio does not work any longer.

Description: We synchronize registry settings for the flashdisk and internal EMMC driver for different SOC families. The settings will be the same on all our module families.

Description: Some SDIO drivers failed communicating on Apalis and Colibri T30.

Description: If you disconnect USB Client while one of the CPU cores will go to 100% load which makes the system very slow.

Workaround: Reboot after disconnecting the USB OTG cable.

Description: Add the possibility in the registry to customize the behavior of the temperature dependent frequency throttling. The new settings are docuemnted here: https://developer1.toradex.com/knowledge-base/resource-manager-registry-settings#Temperature_Throttling_Configuration

Description: Due to some differences in power management in WEC2013 and CE 7 we have to modify the PowerCap registry setting for the display driver in order to make the backlight enable / disable working.

Workaround: Manually set PowerCaps key in [HLKM/Software/Nvidia Corporation/NVDDI] from 0x11 to 0xFF for WEC2013

Description: Allow system to add and remove CPU cores dynamically during run time. Feature can be switched on and off by a registry key. This features will reduce power consumption by more than 0.5 W (T30) in idle state. Check more details here: http://developer.toradex.com/knowledge-base/resource-manager-registry-settings#Dynamic_Core_Disable

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: 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

Description: .

Description: If you don't have a "\USB HD\Images" device attached the directory listing is not shown after "Backup" is clicked. Fixed with Update Tool 6.0.11 (https://docs.toradex.cn/103231-tegra-update-tool)

Workaround: Insert a USB memory device with a folder Images

Description: If you run the restore of a registry section, the update tool overwrites the image section and the device does not boot any longer.

Description: This allows you to copy files from the flashdisk to any location before most drivers are loaded. The feature is documented here: https://developer1.toradex.com/knowledge-base/autocopy#EarlyAutoCopy

Description: If there was no registry section in the flashdisk the device did not boot properly (i.e. keyboard was not loaded). In order to prevent this, we let the device boot and output an message on the debug port. Nevertheless you will not be able to store registry changes.

Workaround: Flash the device using *.cfg files or NVFlash in order to support the create a registry section in the internal storage.

Description: If you attach a USB hard disk the drive will not be seen on the device as it takes to long to initialize and WinCE stops trying to get it mounted.

Workaround: For Tegra family you can use the hotplugdelay key (http://developer.toradex.com/knowledge-base/colibri-t20-usb-host-driver-registry-settings#Hotplug_Delay) and set it to a value depending on the init time of your disk (6000 to 8000ms).

Description: Added support for T30 ISP(Image Signal Processor) to process Bayer Data from Image Sensors.

Description: SD devices stop working if insert and remove SD Card quite fast after each other.

Description: When counting bad blocks in error reports we do not count all bad blocks. The number is too low.

Description: The installable touch driver possibly does not work due to an already installed touch driver. This one has to be removed from the image.

Workaround: Rename the DLLs in the following Registry keys: [HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\14371_1\...] [HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\14371_2\...] [HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\291_1\...] [HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\3823_1\...] [HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\3823_2\...]

Description: GDI VideoRendering does not work properly

Description: Standardize version output across all our images.

Description: Since Image V2.0 beta 1 there is an issue that suspend / resume only work one time. The second time the device does not resume from suspend.

Description: Serial Cameras (MIPI CSI) are now also supported

Description: Add support for built in 1-Wire controller to BSP in order to support user mode access to interface.

Description: At the moment we print warnings even with one ECC failure bit. We increase the threshold: If we reach half of the max correctable bit errors the an "Ecc.Corrected(x)..." message will be shown.

Description: Since WEC2013 the web-server seems to have an additional timeout after loading a certain amount of resources. The timeout is set according to registry setting ConnectionTimeout, it looks as if the connections on WEC2013 are not closed as it was on CE 7.

Workaround: Reduce ConnectionTimeout in the registry (See https://docs.microsoft.com/en-us/previous-versions/windows/embedded/ee499476(v=winembedded.80) )

Description: Left and right audio channels sometimes get swapped.

Workaround: Increase CPU frequency reduces the chance of this issue to happen.

Description: Encoding H.264 videos, for example from camera input stream, fails.

Description: Users can now use menu inside registry editor to save or clear registry. There are also command line switches avalible -> /F to save /C to clear They can be used in combination with /S for silent.

Description: When importing reg file some keys get shown twice. Key is still created only one but view is wrong.

Description: Importing registry keys under HKEY_CURRENT_USER would fail.

Workaround: Contact support to get new version of registry editor.

Description: In case you do not have a USB Device inserted, the Updte Tool will not show a dialoge for backup or restore directories.

Workaround: Get latest update tool from here: https://docs.toradex.cn/103231-tegra-update-tool.zip

Description: In order to support fail save images in future, we added an other section for a fail save image in the flash layout.

Description: Since 2.0 beta 4 on Apalis T30 external PCIe devices are not loaded any longer. This was fixed with a updated gpio.bootconf. This change affected the bootloader only.

Workaround: Set the gpio.bootconf string to the following value: "[gpio_146] pull=none [gpio_147] pull=up [gpio_148] pull=up [gpio_149] pull=up [gpio_150] pull=up [gpio_151] pull=up [gpio_170] pull=up [gpio_171] pull=up [gpio_186] outmode=tristate pull=none [gpio_187] outmode=tristate [gpio_231] pull=up [gpio_237] pull=up [gpio_238] pull=down [gpio_69] outmode=tristate [gpio_71] outmode=tristate [gpio_224] pull=none [gpio_146] outmode=tristate"

Description: V2.0 contains all changes of the 2.0betaX versions.

Description: There are some pins on the Colibri / Apalis T30 module which have multiple signals multiplexed on it. The following pins are tristeded in the Bootloader: 136, 138, 95 (GPIO 71 and 69). Configuration is done in the gpio.bootconf, see also issue 7823.

Workaround: Reconfigure the signals on these pins after boot-up through the GPIOLib or directly in the GPIO registers.

Description: GPIO configuration can be done in the gpio.bootconf in the config block. Use the string syntax preset and additional settings documented in the new GPIO Lib http://developer.toradex.com/software/windows-embedded-compact/toradex-ce-libraries-and-code-samples#toradex-ce-libraries-for-vfxx-and-imx6. Please keep pre-configured string which is already there.

Workaround: By using the Bootloader Customizer Kit it is possible to set the GPIOs while bootup. See http://developer.toradex.com/knowledge-base/bootloader-customizer-kit for details. Since V1.4beta3 there is an additional HW Register patch feature in the Bootloader. Get in touch with the support team to get more information.

Description: If you update the splash screen using the Update Tool, the buffer strength (ss.bsTeg in Config Block) is set wrong (0) in the bootloader. This leads to a bad image quality. This is fixed in UpdateTool 6.0.8.

Workaround: Manually reset ss.bsTeg to -1 (0xFFFFFFFF) in the config block. http://developer.toradex.com/knowledge-base/splash-screen

Description: When you call PurgeCom (or DiscardOutBuffer in .NET), some data which already have been sent out is sent again.

Workaround: Do not use these functions for now.

Description: Due to a strange behavior with RAM Based Hive implementation RegFlushKey doesn't work. This was fixed in 2.0b4

Workaround: Use RegSaveKey prior to BSP 2.0b4

Description: If a custom driver or feature requires the flashdisk during boot, we have to make sure the flashdisk is ready. Added Wait4Flashdisk driver but not activate it by default

Description: If you change Regional Settings (Start -> Settings -> Control Panel: Regionsl Settings), the modifications are lost after reboot also you save the registry. This is an issue since image 2.0 beta 1.

Workaround: Currently no workaround

Description: WiFi settings like preferred network or ad hoc settings are not persistent across reboot.

Description: Some pin configurations are touched in a generic part of the source code. We migrate that configuration to the boot.bootconf config string. Affected Pins on T20: GPIOsV0 to V7, T30: GPIOs S2 - S7

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

Description: It is now possible to measure interrupt latencies using ilttimings.exe tool from microsoft.

Description: Add an IO control which returns a Unique ID which can be used for security features. IOCTL_HAL_GET_DEVICE_INFO and IOCTL_HAL_GET_UUID are implemented. Use IOCTL_HAL_GET_DEVICE_INFO, IOCTL_HAL_GET_UUID is deprecated.

Description: Local(SensorChip) shutdown temperature on LM95245 temperature sensor was set to 85°C (default). We now increase this temperature in bootloader init to 120°C

Description: Add possibility to configure Apalis T30 LVDS controller. Check this devleoper page for the new keys added to the registry: https://developer1.toradex.com/knowledge-base/display-driver-registry-settings#Settings_for_Colibri_Txx_and_Apalis_Txx_Modules_Only

Workaround: Use the GPIO lib to manually set up the right configuration.

Description: Bayer sensor functionality broken since 1.3, only YUV sensor works.

Description: On Windows 10 by default a Serial (COM) driver gets loaded if you you load the function driver rndisfn.dll. You may need to set the TCP/IP settings of the RNDIS device.

Description: Since Image V1.2 audio playback over HDMI/DVI is not supported any longer.

Description: Screen Rotation of 90 or 270 degree causes freeze on Video Playback

Description: In rare situations explorer or other startup application might generate an exception or not start and the system will be stuck at the splashscreen.

Description: Add new registry editor that fixes issues with registry import.

Description: Bootloader shows "Unknown Product ID" while booting for Colibri T30 IT (ProdId=30)

Description: WriteFile with small amount of data either does not send out data on physical line or does not return.

Workaround: Disable Multicore (pex.mpenable=0) or set Thread Affinity to one single core. Disable DMA for write and read: Set Registry Setting DmaSettings for UART port to 0.

Description: When doing clean sysgen using our workspace some files did not get copied to release directory.

Workaround: Rebuild ToradexFiles subproject manually.

Description: Copy/Paste and Drag and Drop doesn't work on with the Explorer on WEC2013.

Workaround: Use command line to copy files.

Description: If no serial Number was found the Update Tool prompts the user to enter a number. This number was stored in a wrong order to the config block. This was fixed in Update Tool 6.0.4

Workaround: Use Update Tool 6.0.4 and later.

Description: When switching from Linux to WinCE the config block gets lost. This means the module looses its serial number / MAC Address.

Workaround: Manually set this information in the config block or by opening the new Update Tool 6.0.6 in GUI mode.

Description: SD Cards running with 8 bit bus width works only in read mode. 8 bit bus with support was added in 2.0 beta 1 (Issue 14782).

Workaround: Manually de tristate data pins 3 to 7 to get it working.

Description: If you have any other application running while doing production programming, it can happen, that the restore fails.

Description: Allow launching BAT files and using relative paths in autorun folder. This makes obsolete the workarround to launch bat files documented here: http://developer.toradex.com/knowledge-base/autorun#File_Types .

Description: Earlier image download packages contained nvflash.exe and update batch files to program modules using recovery mode. In order to provide a separate NVFlash / Recovery mode bundle we remove these files from the image release bundle. All NVFlash Files can be bound here: https://docs.toradex.cn/103464-nvflash-recovery-toolset.zip

Description: The RNDIS driver which is used for platform debugging is not working properly on Windows 10. The identifier will change to the following: Class 0xEF Subclass 0x04 Protocoll 0x01 For platform debugging a new RNDIS device will be installed. Make sure you update the RNDIS connector IP after upgrading to this Image / Bootloader version.

Description: Currently MAC gets loaded from the configblock once and is then stored in the registry. This leads to issues when Backup/ Restore registry in production programming in images 2.0b1 and onward. Since 2.0b2 the MAC address is always loaded from the config block other than you saved the "NetworkAddress" in the device registry.

Description: On some modules the Ethernet controller sometimes is not detected during the boot process or the link drops during run time. Most often this happened if there was activity on the GPIO Y0 to Y3 pins (i.e. SPI).

Workaround: Reset the Ethernet Controller By generating a low pulse on GPIO V4 (Colibri T20) or GPIO DD0 (Colibri T30).

Description: Some displays pixel clock with a higher accuracy. By default the display drivers uses the most efficient clock source. In issue 9528 we have introduced a registry key registry key forcePLLD in [HKLM\Software\Nvidia Corporation\NVDDI\LCD] that allows you to optimize in accuracy. We further optimized the accuracy of the clock in case you are using the forcePLLD key.

Description: Possible lockout of 2D and 3D Hardware interface leads to screen freeze. The module itself is still running the screen gets not refreshed any longer. This mainly happens if you do only read operations of a DC where you previous have been painting on with the 3D and 2D HW unit.

Workaround: Periodically do some write access on surfaces (i.e. background pictures) you only read from.

Description: When not touching the dcb.fDtrControl (leave it set DTR_CONTROL_ENABLE) the module will freeze if you close the UART COM3 port the first time.

Workaround: If you don't use flowcontrol set dcb.fDtrControl=DTR_CONTROL_DISABLE to avoid this issue.

Description: On Windows Embedded Compact 7 with certain screen resolutions you see vertical lines when the mouse cursor is bellow the bottom screen edge during a mouse click. The lines are shown when the mouse button is released.

Description: RAM timings for Colibri and Apalis T30 are improved. If you ever flashed a custom bct before either flash latest image using nvflash or flash default.bct before flashing new image with the Update Tool.

Description: On the Apalis T30 only 1 GB RAM is supported also you have a 2 GB module. Either flash latest image using nvflash or flash default.bct using UpdateTool 6.0 or later.

Description: System hangs seen on bootup of the module producing an EMEM Error message on the serial debug port.

Description: Improved memory timings lead to better performance on graphics and memory bandwith. With this release T30 has better on memory and graphics performance.

Description: Memory allocation waste has been reduced by minimizing slots allocated. This mainly is an improvement form OpenGL applications with lots of textures.

Description: Since image V1.4 a improved ECC handling has been introduced (issue 10351). To make use of that you had to upgrade to 1.4 using NVFlash. From now on you can also use the UpdateTool 6.0.1, which now supports migrating to new ECC handling with image V1.4 and newer. You can also upgrade from Images before 1.4 with the new Update Tool and you will also get the new ECC handling.

Description: Increased available Kernel Virtual Address space by 480 MB. Allows to map more memory in kernel space (by graphics and other kernel drivers)

Description: Due to power management optimization in image V1.3 and later audio loopback is not working any longer on the T20. Registry Key PowerDownTimeout was introduced to control the power down behavior. Set PowerDownTimeout = -1 in order to prevent the codec being powered down.

Description: In order to be in sync with IMX and Vybrid module family we update the components being included in to the platform configuration.

Description: Error message "Virtual free failure!!!" is shown if you set lcdbs key in display settings. This error message doesn't have any influence on the system at all.

Description: The WEC2013 Toradex Imagae contains some binaries used for debugging. Put the latest version of these into the image.

Description: Pins of the serial port are reconfigured with every open and close of the serial port. This is an issue for customer using some UART pins as GPIO Pin. To solve this issue set up a PinMux configuration (Registry key PinMuxConfig) that matches your requirements: See all possible configurations here: http://developer.toradex.com/knowledge-base/serial-ports

Description: In order to support more UART configurations on all Tegra modules, we have introduced a PinMuxConfig Key in the registry. See more details here: http://developer.toradex.com/knowledge-base/serial-port-registry-settings#Tegra_Family_Settings

Description: Updated the explorer shell with the latest binaries.

Description: Due to version number in the version section of the PBXML file the workspace can not be opened.

Workaround: Fixed in latest Windows Embedded Compact 2013 (CE 8) Worspace file. Get 1.4 beta 1 bis version from the download server.

Description: In some rare cases single characters transmitted over UART get lost. This is depending on the baud rate and characteristics of the data being sent.

Description: When closing an application longer interrupt delays can be introduced. These due to some higher priority tasks in the OS (L2 Cache Handling) which are non interruptible.

Description: Composite TV Out using NTSC is supported by setting the bootupstyle to 0x6 or 0xa in the registry and attaching CRT_GREEN to the composite input of a monitor.

Description: Module will not suspend if a device is attached to the USB Client port (i.e. Active Sync). In rare cases suspend also does not work with a USB memory device attached.

Workaround: Detach USB Host / Client before suspending.

Description: If you have disabled the explorer.exe shell, the time set by SetLocalTime is gone afer a reboot.

Workaround: An updated RTCSync tool is part of image/BSP V1.4beta3 and later.

Description: If you migrate from one of the latest Linux Images to WinCE (using NVFlash) the device looses its serial number. This means it also looses its Ethernet MAC address.

Workaround: Add the serial number manually to the ConfigBlock. See also this developer webiste: http://developer.toradex.com/knowledge-base/mac-address

Description: There are some rare cases of data corruption on receiving UART data if DMA mode is used.

Description: Add support for the fixup variable "dwOEMDrWatsonSize" for customers building their own OS image.

Description: Visual Studio 2013 debugging fails with Error "Unable to import library VSDebugEng.dll ! Program will exit".

Workaround: Copy webservices.dll manually to the target folder \Flashdisk\System\ . Get in touch with Toradex Support to get the file.

Description: Digital Audio (S/PDIF OUT) is not properly supported on Colibri T20. The digital output stream cannot be recorded.

Workaround: The Copy-Protection must be deactivated by writing the value 0x00000004 to the physical address 0x70002540.

Description: In the Configblock section pex the number of CPUs to be active can be set now. This field can have any value from 1 to the maximum number of CPUs of the module. See also https://developer1.toradex.com/knowledge-base/processor-extensions-config-block-settings .

Description: Fix for cameras not using their own external crystal. We recommend to use the latest camera plugin. Send a request to the support team to get the the plugin.

Description: The default pin configuration for UART2 on Apalis T30 is not correct, wrong pin configuration is used.

Workaround: Setup pins manually by using GPIO library. Correct Setting is MXM Pins 130 (CTS), 128 (RTS), 132 (RX) and 126 (TX).

Description: Suspend/Resume on Colibri T20 in image 1.4 beta 1 does not work as stable as in release 1.3.

Description: The Silverlight references in the Toradex SDK do not match the Windows CE image 1.3b2 and later. See workaround for more information.

Workaround: Applications running on Images before 1.3 have to be rebuilt with SDK v0.2, applications running on 1.3 and later on have to be rebuilt with SDK v2.0. You get the SDKs from here: https://docs.toradex.cn/102481

Description: To improve durability of NAND Flash on Colibri T20 we add additional ECC bits. With this more read errors per block can be corrected, so blocks are marked as bad later. Note: To make use of the improved error correction you have to update your image with NVFlash or with the Update Tool > 6.0.0. You also have to use NVFlash or the the Update Tool to downgrade to image before 1.4beta2.

Description: T30: Add camera support, T20: Fix camera support (was broken since V1.3beta1)

Description: Update the Ethernet driver for Colibri T20 and Colibri T30, in order to improve Ethernet performance.

Description: Pin group SDIO1 pull-state is wrongly set to "no-pull". The reset default pull-state is "Pull Up". Use this as default value.

Workaround: Manually change the pull state to "Pull Up" using the gpiolib.

Description: Some SD memory cards are not working reliable. When they are getting full and/or you do heavy write access, they stop working (error 19 or error 31). This can be fixed by increasing the read command timeout from 1sec to 2sec.

Workaround: Remove and insert SD Card or get in contact with the support team to get a driver that fixes this issue.

Description: Users that need to intercept IOCTLs have now the chance to intercept IOCTLs to implement their own functionality. Please get in contact with the support team to get more information about that.

Description: HDMI displays were flickering while the splash screen was shown. When the WinCE desktop appeared, the picture got stable.

Description: Added overlay support for OpenGL. In full screen applications image flipping is now used instead of blitting the framebuffer contents.

Description: Add feature to globally enable or disable the mouse cursor via API. See documentation here: http://developer.toradex.com/knowledge-base/mouse-cursor#Hide_Mouse_Curser_Globally_From_an_Application

Workaround: Change the following registry key: [HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\NVDDI] "HwCursor"=dword:00000000 ;0: Mouse Cursor disabled, 1 : Mouse Cursor enabled

Description: Bring CE8 utilities, tools and feature set to the same level as CE6 and CE7

Description: UARTD (Nvidia Name UART 3) only used RX/TX. CTS and RTS have not been configured.

Workaround: Configure CTS and RTS after opening Serial Port using the GPIO lib.

Description: The CPU frequency does not go bellow 500MHz when DVI/HDMI is plugged in at boot since image V 1.3 beta 3.

Description: There was a dependency between the Touch, Audio and Analog Input Library. They could not be used independently. Please use the latest ADCLib from the library package 1.9. As long as the package is not availabe, please contact the support to get the latest version.

Description: The DispOnDelay was not working properly. DispOnDelay is now supported in bootloader. Negative values (DISP_GPIO toggle before LCD signals) are not supported yet.

Description: There is some potential risk in the handling of runtime badblocks. The bad block handling was improved in this release.

Description: When using the OEMQueryPerformanceCounter in a multi-core environment it could happen, that that time-slips occur.

Description: Some USB devices, i.e. UVC USB Cameras, are not shown in the system, when they are plugged into a running system (Hotplug). This can now be fixed by adding a key "HotPlugDelayMS" with the count of milliseconds the system should wait for the device. Add the key to the appropriate USB Host registry settings (i.e. HKEY_LOCAL_MACHINE\Drivers\BuiltIn\USBEHCI1]). For UVC Cameras 100ms should be fine. More Details here: http://developer.toradex.com/knowledge-base/colibri-t20-usb-host-driver-registry-settings#Hotplug_Delay .

Description: Saving config block data overwrites too much RAM. It's not critical because this RAM area isn't used at the moment.

Description: We have seen, that it does not make any difference in the power consumption if we use 40MHz or 216MHz as minimum DFS frequency. On the other side we have a improved interrupt handling by not going bellow 216MHz. For this reason we set the default minimum frequency for DFS to 216MHz.

Description: Suspend/Resume is supported now on Colibri T20. Check the other "Power Management" related issues for limitations.

Description: Publish Release Version V1.3 including all changes from V1.3beta1 to 1.3beta3.

Description: We saw problems with the handling of runtime badblocks. This could even lead to data loss in rare cases. We identified and fixed this problems in this release.

Description: Set GPIO V3 (SODIMM 45) to GPIO in by default. Was set to CLK12M_Out before.

Description: Power down the audio codec on the Colibri T20 module when the it is not used.

Description: Disable HDMI interface when it is not used. Disabling it reduces power consumption of the modules.

Description: Set default Bootupstyle from LCDAndCRT to LCDOnly for Colibri modules. Do not change bootupstyle for Apalis modules. See also http://developer.toradex.com/knowledge-base/display-driver-registry-settings#Settings_for_Colibri_Txx_and_Apalis_Txx_Modules_Only .

Description: If USB_ID Pin (SODIMM 135) is not in a defined state USB devices can not be attached during runtime. Remove these influence of the ID pin to these drivers.

Description: Polarity for UART control signals can not be changed in the Registry.

Description: LCD drive strength can be set in the registry (lcdbs). Check the display registry page for more details: http://developer.toradex.com/knowledge-base/display-driver-registry-settings . In the bootloader use the ss.lcdTeg key to set the drive strength.

Description: After disabling and enabling the touch screen the touch coordinates are wrong. This only affects customer having the screen output rotated.

Description: The printing feature of Windows Embedded Compact 7 was missing in our standard image.

Workaround: Customers can build their own image with printer support using Platform Builder.

Description: The backlight pin was toggling for about 2 micro seconds while booting.

Description: Slight performance optimization when setting up DMAs in Kernel and Drivers using DMA.

Description: The player.exe can not be closed after playing WAV files. This is not an issue for customer playing WAV files in their own application.

Description: The Version Info of the Update Tool is not working properly on the Apalis T30. For ID there is shown "UNKNOWN" where it should be "APALIS TEGRA".

Description: This Windows Embedded Compact 6 image contains Microsoft QFE Monthly Update February 2014.

Description: Bootloader updates was not working on T30 modules when using the UpdateTool.

Workaround: Before image 1.3 beta 1: Use the latest update tool or use recovery mode and NvFlash for bootloader update works: http://developer.toradex.com/knowledge-base/txx-recovery-mode

Description: PS2 keyboard and mouse only works with DFS disabled. Fixed in 1.3 beta 3 as DFS min default setting is set to 216MHz.

Workaround: Set min CPU frequency to 216MHz: http://developer.toradex.com/wiki-articles/resource-manager-registry-settings

Description: NvFlash V1.1 fails to update Colibri T20 and T30 modules which are new or have a completely wiped flash memory.

Workaround: This issue only appears in the loader.nb0 V1.0 which comes as part of the Toradex Tegra BSP V1.2. Using loader.nb0 V1.1 or higher fixes the problem.

Description: Dial-up connections get disconnected immediately after dial-in. Issue was related to some not supported comm event masks. There have also been added some unimodem related keys in the registry.

Description: The Audio Codec was not supported on the Colibri and Apalis T30. This means that there was no audio support on these modules.

Description: Using SODIMM 173 as interrupt source freezes the system as soon as an interrupt occurs. Other SODIMM pins might also have the same effect.

Description: Fixed two small syntax errors in plattform.reg (line 303) and project.reg (line 224) reported by customers. Only affects customers that build their own image.

Description: Reduce image size by removing sysgen_appdebug. The debug feature will still be available as we manually add a dedicated set of DLLs.

Description: When using an Apalis T30 on Ixora the host is not working on the USB OTG (X9) also when manually switching the settings in the registry.

Workaround: Manually toggle the USBO1_EN (GPIO T5 / 157, MXM274)

Description: There is no support to configure multiple SDIO instances as for the Colibri T20. If different pin setups are used by customer this needs to be added.

Description: After Windows Embedded Compact 7 booted the CPU is 100% loaded for around 10 seconds. This behavior is normal. It's caused by the kernel cleaning dirty pages in a idle priority background thread.

Description: If the module gets suspended during playing audio, audio will not work fully work after resuming.

Workaround: Stop audio playback before suspending.

Description: A floating/toggeling CTS signal can cause the serial driver to load 100% of the CPU, even if no handshaking is enabled.

Workaround: Set registry key Numberoflines to 2. Registry key is documented here: http://developer.toradex.com/knowledge-base/serial-port-registry-settings#Colibri_Tegra_Registry_Settings . This was introduced with image 2.1b2.

Description: SysAdmin (and also RemoteAdmin) isn't supported on WEC2013. It's currently not planned to support them. You can contact us if you plan to use this feature.

Description: Officially Microsoft does not support the webinterface (Remoteadmin) since CE 7. Migrate the interface to WEC2013 in order to provide an easy way to administrate users and remote file access.

Description: Support Registry Settings for Drive Strength on the SD Card interface.

Workaround: Modify the HW registers directly. e.g have a look at the Tegra 2 TRM chapter 11.1.7 https://developer.nvidia.com/tegra-2-technical-reference-manual e.g for DATA one you would modify register 0x700008f4

Description: Vidoes that are streamed are sometimes not decoded correctly: Artifacts are shown or some parts of the pictures are missing.

Description: Backlight enabling / disabling is not fully supported as described for the PXA modules: http://developer.toradex.com/knowledge-base/backlight. When back light gets disabled the whole display drivers is disabled. This is a potential issue for some customer hardware (i.e. flickering screen when re enabling the backlight).

Description: At the moment single CPUs can not be shot down to save power.

Workaround: Use Dynamic Frequency Switching to throttle down CPU frequency. This is enabled by default. (See also: http://developer.toradex.com/wiki-articles/resource-manager-registry-settings) Cores can also be disabled statically in the bootloader (pex.mpenable=0).

Description: If there is no serial port available customers can not log any debug messages. On the PXA family debug messages can be written into a buffer which can also be checked after a reboot. This feature is not available on the Tegra modules yet.

Description: While the Windows CE device's USB client port is connected to a host (e.g. for debugging), the network connection is not accessible. Reason: The USB client connection creates a virtual COM port COM0 and an additional network connection through COM0. The Windows CE device's network traffic is then routed to COM0 by default.

Workaround: Use the Windows CE command line to change the routing table: 1. route print com0 Look at the COM0: row in the interface list, and remember the number shown in the first column . 2. route delete 0.0.0.0 IF Where i is the number taken from step 1. Repeat these steps each time you disconnect and re-connect the USB cable.

Description: Some newer DVI displays seem to have compatibility issues with T30 modules regarding DDC.

Description: When using playsound, the function returns immediately after the data has been written to the audio out buffer. This means if there is enough space in the buffer, the function copies the data and returns directly.

Workaround: No Workaround

Description: When display configuration is not the same in bootloader and registry, this could lead to some strange behaviour during runtime (e.g. after resuming display driver from system idle).

Workaround: Always set display settings in bootloader and system registry.

Description: Currently the UART driver triggers RX events only once. If the event is not handled by the application and the data is not read, there will not be signaled any other RX event, also not if new data arrives on the device. Trigger a manual read data to reenable the RX events.

Workaround: Make sure you do not miss any RX event. If not possible, set a timeout after which you will manually trigger a manual read.

Description: Tegra hangs in suspend at random times

Workaround: If you don't need ethernet, disable USBHCI2 which will disable it. Se also this developer website about how to disable drivers: https://developer.toradex.com/knowledge-base/disable-drivers#disabling-drivers

Description: HttpSendRequest() can take more than 30 seconds to return.

Description: OpenGL drawing artefacts in 16bpp mode

Workaround: Use 32bpp mode: set mainpanelbpp in the registry

Description: Allow user application to query ECC algorithm which is currently used by the NAND flash.

Workaround: Read hardware regsiter 0x700080CC and check bit 0. I case it is set to 1, BCH16 is used, if it is 0 RS4 NAND ECC is used.

Description: After several start/stop cycles start fails

Workaround: If possible avoid starting/stopping the graphs.

Description: If you have a roated screen, videos played in full screen mode are shown correctly. If you still want to get the videos rotated, set the registry key [HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\NVDSHOW] NV_VIDEO_RENDERER_FULLSCREEN_ORIENTATION to 90 or 270.

Description: Some Colibri T30 might sporadically hang or show random exceptions while booting. This is because of a memory timing incompatibility.

Workaround: Detailed description and workaround are available at: http://developer.toradex.com/knowledge-base/nvflash-2122-ram-timings-issue-on-colibri-t30

Description: After adding additional locals through the Toradex .cab installer, still only the regional settings English(United States) can be used. Any other region setting prevents the system from booting correctly.

Description: Network credentials cannot be saved in WinCe6 V2.2.

Workaround: Please consider to use SMBConnect with configurable parameters run it through Autorun, see the detailed explanation here : http://www.toradex.com/community/answers/34823/view.html

Description: Multimedia Audio (MP3, Video) cannot be played on a USB audio device.

Workaround: The AudioRouter can be added to route Multimedia Audio to a USB speaker. Refer to the following community post for details: https://www.toradex.com/community/questions/21399/play-audio-from-usb-speaker.html

Description: Sharing USB memory device or SD Memory Device using the "Mass Storage Class" with an external PC does not work properly. The device is not shared after booting neither when insert remove the storage. The only thing that solves the issue is plug / unplug the USB function cable. Sharing the internal flash storage works fine.

Workaround: Remove [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\USBFN\] "Order" key. This will force the USBFN driver to be loaded with the lowest order and gives the SDIO driver some more time to get loaded.

Description: When using UART DMA, the parity check is ignored on UART Rx data.

Workaround: Use PIO mode instead of DMA in the registry. Set DmaSetting=0 https://developer.toradex.com/knowledge-base/serial-port-registry-settings#colibri-tegra-registry-settings

Description: USB OTG is not implemented on the Colibri and Apalis T30 modules.

Workaround: Use manual switching: http://developer.toradex.com/knowledge-base/usb-on-the-go

Description: The CE7 exception handler seems to have a problem if the exception happens in thumb mode (instead of the normal arm32 mode). This also happens if not explicitly using Thumb mode. This is an issue if the exception handling is triggered by any uninitialized function pointer with an odd value.

Workaround: None. This is a Microsoft code issue. Microsoft is aware of it but currently doesn't plan to fix it.

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 USB Host power enable pins can only be configured on a global level for all host ports (se also here: http://developer.toradex.com/knowledge-base/colibri-t20-usb-host-driver-registry-settings#power-enable-pin-settings ). This needs to be modified to allow having different enable pins for all ports. Also modify the default pin for the Apalis Modules.

Workaround: Modify the power enable pins manually with the GPIO Config Library or Tool.

Description: Disconnecting the USB client connector causes the module to lag. This was observed when using USB as SERIAL_CLASS device.

Description: Playing videos in a loop with the integrated video player does not work. Also the fullscreen mode is not supported.

Workaround: Instead of loop it, just stop it shortly before the end and then re-start it.

Description: There is a memory leak in the SDIO driver. When inserting / removing SD Card some memory is not freed. This specially can be an issue for customers having SODIMM 45 floating (Card detect) and still have SD Card driver enabled.

Workaround: Customers not using SDIO interface should disable the driver in order enable a interrupt on the card detect pin.

Description: Useful to debug system freezes or interrupt problems

Description: When running Camerademo application or play videos, initial few frames will be blue if MainPanelBpp is set to 32 bit depth. NOTE: This behavior is normal, this is the overlay key color.

Workaround: Set BPP to 16 bits or change the overlay Key Color: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MediaPlayer\Preferences] "VideoOverlayKeyColor"=dword:00000841

Description: Some tools do not save the registry any longer since 2.0 beta 1.

Workaround: Use the Update Tool to save the registry.

Description: When DST is not active and SoftRTC is disabled (default on Tegra Modules is Enabled) the current date/time reported by the system is not precise and lags few minutes per hours during runtime. This is a bug in the MS code.

Workaround: If you have issues with DST not running correctly there are two ways to fix this. 1. Enable SoftRTC. 2. Go into registry under HKLM\Time Zones and select your timezone. There is a subkey "Dynamic DST" with entries for each year. To fix it create a new entry for year when you have issues and copy value from previous year.

Description: A Windows CE like shell (desktop) should also be available for Windows Embedded Compact 2013

Description: Add USB CDC Class Driver to the Image

Description: Bootloader SS few config parameters would be corrupted.

Description: Support new NAND Flash on [00221201] Colibri T20 512MB IT V1.2B

Description: A T30 module does not provide any display output when used with a Viola board and an EDT display.
