WEC T20 / T30 BSP Release Details

Description: When Pulugging and Unplugging USB Function cable several times, it may happen that USB Function driver does not work properly anymore. This is easy to see when using ActiveSync. the connection to the Host PC is not working properly after the second or third attempt to plug/unplug the cable.

Description: Writing to HighSpeed (50Mhz) capable SD cards fails on T20 on Image 2.3

Workaround: Set [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\SDIO] "MaximumClockFrequency" = dword:48000000

Description: The Bootloader is running from address offset 137MB so OS images that overlap this region will overwrite the bootloader code on load. Relinked eboot to run from offset 192MB to allow bigger OS Images NOTE: New Update Tool 6.0.21 is needed to update only bootloader as old update tool will identify new eboot.nb0 as OS Image

Description: GUI in XAML applications sometimes shows artefacts of incomplete redraws.

Workaround: Ask Toradex for a specific XAML renderer optimized for i.MX6, and add the registry value: [HKLM\SOFTWARE\Microsoft\XamlRenderOpenGL] "DisableDDAcceleration"=dword:1

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

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: 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: This version was never officially released and is an internal version only.

Description: .bat Files are not associated with cmd.exe

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: Added a dummy battery driver to the image. This driver does not access any HW, it just reflects the state of a memory mapped file, so the battery HW can be read out by a customer application or driver and written into this memory mapped file. There is a sample code available here: https://docs.toradex.com/106587-battery.c?v=1

Description: BootRom expects eMMC to be in FastBoot mode, but it's not so it always wastes 2s waiting for FastBoot Ack. After this timeout it will try to do normal boot.

Description: WEC2013 App debugger is not working on T30 on image V2.2b2

Workaround: Use VSDebugger from latest release.

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

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: USBO1 port on Apalis has his own power enable signal (USBO1_EN) which is needed to be used in Host mode, but was not driven.

Workaround: Configure OTG port as Host and set Pin 274 to GPIO Output 1

Description: USB can turn non-functional after changing USB registry values. This was now fixed and the USB instances can be loaded in any order

Workaround: Change the "order" value of [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\USBEHCI1] to assure it is loaded before the other USBEHCI drivers.

Description: In some cases LVDS signals are not toggling any longer after switching from splash screen to the main WinCE desktop. This is due to some problems in the LVDS converter chip. Fixed by not disable/enable display controller between splashscreen and windows ce desktop. NOTE: This can only be done if the Splashscreen resolution matches the desktop resolution. In that case the complete display timings will stay as configured in Splashscreen. To revert to previous behavior set "UseSplashSettings"=0 [HKLM\SOFTWARE\NVIDIA Corporation\NVDDI]

Workaround: Either disable the splash screen or toggle backlight pin in a user space application, to disable/enable the LVDS converter.

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: Slightly increase USB performance by changing some DMA traffic parameter.

Description: RAM DFS was not introduced in a earlier release but not enabled by default. This feature is enabled from now on by default.

Description: The module freezes under following circumstances: - Device gets out of the user idle mode (D2) - Device does not draw anything new on the screen (at least not hardware accelerated) - Device has workload on the GMI Data bus

Description: Custom images can now be as large as 512 MB without modifying the config.bib file. Please be aware that the limitation is the module: If you have a module that only has 256MB RAM, you will not be able to flash an image with a size larger than 256 MB. Remark: On the Colibri T20 it will be less, the max size is computed like this: RAM Size of the module - Carveout Size (64MB by default).

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

Workaround: -

Description: Some OpenGL operations are slower compared to release 1.4. This problem started showing up from version 2.0.

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: This version was never officially released and is an internal version only.

Description: Added latest Update Tool 6.0.14

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

Description: Production Programming script is executed with wrong current-path.

Workaround: Insert a statement IF EXIST AutoRun\LauncherEx.exe CD AutoRun into your batch script.

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

Workaround: Select the font manually in the Format -> Font... menu. Save the registry to make this change permanent.

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: 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: Added Update Tool 6.0.12

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

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: 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: Not all config block settings that are listed in the bootloader and config block editor are supported by the Tegra Modules.

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: If you set USB to fullspeed (USB 1.0) you sometimes get data aborts and the device driver crashes. This is fixed with this release.

Description: VSDebugger currently waits 30s before its ussable. Now connection gets established as soon as a network connection is established. With this version you also get the IP information on starting the debug client. See also updated debuging documentation: http://developer.toradex.com/knowledge-base/application-debugging-over-ethernet-using-visual-studio-2008#One_Time_Preparation

Description: The two config block settings dbg.regread and dbg.regwrite have not been supported yet. These settings allow to prevent regsitry from be read or written from/to the flash storage.

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.com/103231-tegra-update-tool)

Workaround: Insert a USB memory device with a folder Images

Description: The level 2 cache was reenabled after a suspend resume cycle also it was disabled in the config block (pex.l2enable=0).

Description: Explorer.exe no longer outputs debug messages.

Description: The video player on WEC2013 did not support full screen playback. This got fixed in the video player.

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

Description: The MasterClock is used by some camera sensors instead of a crystal. It should stay at a constant value.

Description: If a Serial Port is open while data is already received on the line, there is a chance that the system will hang or get very slow, as lots of interrupts will be generated.

Workaround: If RX DMA is not really needed you can disable it by changing "DMASetting"=0 in the UART registry settings.

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://docs.microsoft.com/en-us/previous-versions/windows/embedded/ms884926(v=msdn.10)

Description: Added "NumberOfLines" registry setting for UART to specify number of used lines. This helps avoiding spurious interrupts if unused input signals are floating.

Description: UpdateTool and NvFlash not working properly with Colibri T20 1.1 or older

Workaround: Only use UpdateTool to update and ignore Error until issue is fixed in next release of UpdateTool and NvFlash

Description: Due to some communication issue between the CPU and Ethernet chip it can happen, that the Ethernet chip disappears. This only happens if a lot of peripheral interfaces are used as well as there is some traffic on the Ethernet device. Increase the Transmission FiFo Threshold by setting the registry key TxFifoThreshold in [HKLM\Drivers\Builtin\USBEHCI]. Default value is 0x10, max value 0x3f.

Workaround: Increase the FIFO Burst Threshold in USB2_CONTROLLER_USB2D_TXFILLTUNING_0 register directly in the hardware registers.

Description: The registry export triggered some exceptions, this was fixed with this release.

Description: The support of IOCTL_DISK_GET_STORAGEID for USB mass storage devices was added in V2.0beta3 but did not work.

Description: On the T20 it after fixing issue 15455 it still could happen, that the the network interface does not get loaded.

Workaround: Toggle Pin V5 in order to get the Ethernet chip out of suspend mode.

Description: In the image there is a registry key forcePLLD to increase clock accuracy. So far this does not exists in the bootloader. We enabled the PLLD (higher clock accuracy) in the bootloader by default, this does not affect the image itself.

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: Left and right audio channels sometimes get swapped.

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

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: 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: 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 customer feedback we downgrade the default RAM clock from 800 MHz to 533 MHz. Higher RAM clocks caused higher power consumption. Depending on the use case this results in thermal issues. We will set the timing up to 800MHz again once we have implemented the RAM clock dynamic frequency switching (DFS) on the T30 RAM. If you still want to use the previous 800 MHz RAM timings remove the following lines from the *.CFG files: [general] t30_emc_clk=533000

Description: The CE Test kit did not pass the registry tests due to size limitations of the registry partition. The wize for registry partition was increased from 1 to 3 MB. This change was done in the *.CFG files. The image was not touched.

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

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: Users can now right click on the listview and get context menu where they can add values to the current key.

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

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

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: 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: 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: 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: Launcher is not able to launch *.bat files.

Workaround: Use latest production programming template with LauncherEx that works on 2.0 beta 2 and 3

Description: Dr.Watson can be used to generate CrashDumps that can be analyzed to find out the cause of the crash. This feature can be enabled/disabled in the config block See more details on the following developer webiste: http://developer.toradex.com/knowledge-base/post-mortem-debugging-watson

Description: GPIO_PV3 is GPIO input pin and its pull state is set to Normal. This is not so nice but no big issue. Add a pull state to this pin in gpio.bootconf.

Description: Adapted default pin settings in order reduce power consumption. On the following GPIOs a internal pull up is set: V2, V3, CC7, DDD6 and DD5. Configuration is done in the gpio.bootconf, see also issue 7823.

Description: In some rare cases when plugging in and removing the HDMI connector from the device the system UI can completely freeze. Non UI related components (Ethernet, USB) still work.

Description: GPIO A6 (SODIMM 30) and GPIO B4 (SODIMM 59) are tristated during booting. This is also happens if you configure them as GPIO Output in the bootloader (for example if you use them as ss.bl_gpio). This will be handled with a default config for bootloader gpio settings feature (7823).

Workaround: Pull up or pull down the pin you are using.

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: Add support for NETUI messages suppression.

Description: Add Update Tool 6.0.6 (2.0.9) to the image and BSP

Description: We added a feature to support reading the ID of a USB mass storage device.

Description: Ethernet MAC address was always set to configblock MAC, even for adapters that have a dedicated EPROM storing that information.

Description: The registry editor has some shortcomings when it comes to importing .reg files. Some keys might not be imported w/o error message.

Workaround: Add the missing registry entries manually.

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

Workaround: Rebuild ToradexFiles subproject manually.

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

Description: Closing COM while pending ReadFile could freeze the system.

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

Description: Disable pull down resistors in power management chip due to improve power consumption reasons.

Description: PS2 mouse and keyboards are not supported at the moment on Colibri and Apalis T30.

Workaround: Use USB mouse and Keyboard.

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: 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.com/103464-nvflash-recovery-toolset.zip

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

Description: Custom build another language image doesn't show the selected locale setting in Regional settings Control panel applet.

Workaround: Remove nlscfg.inf and nlscpg.txt files from our release workspace.

Description: When applying images that have been backuped before (production programming) the MAC address gets overwritten. This has been fixes with Update Tool 6.0.4 ( https://docs.toradex.com/103231-tegra-update-tool )

Workaround: Use Update Tool 6.0.4 and later.

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

Workaround: Use command line to copy files.

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

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: RTS Signal toggled during boot phase. This can be an issue for external devices. We also introduced a registry Key, that allows to change the RTS thread priority for users that can not do that in their code. See also https://developer1.toradex.com/knowledge-base/rs485.

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: 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: When the video window has an uneven width, the video output remains black.

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

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: If Debug output is enabled a PCIe device tree is shown on during booting the device.

Description: Using any other setting than ser.port=0 for the debug output did not work.

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

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: USB, Ethernet and VGA is not working on Apalis and Colibri T30 IT products.

Workaround: Use Image 1.4. If only Ethernet ist not working, clear the registry (http://developer.toradex.com/knowledge-base/clear-registry ).

Description: The wince testkit is not running because the define project_cebase is not set.

Description: Prevent the update tool setting negative disp on delays in the bootloader. The bootloader does not support negative disp on delays yet. After updating the splash screen with a module configured a negative disp on delays in the registry it will not boot any longer.

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

Description: In previous beta release default value of pex.cpus was the maximal number of CPUs for the target CPU. This leads to problems if using an old bootloader with an actual image. Default is set to 0 in this release.

Description: .NET CF application do not work on CE 6 since V1.4 beta 1.

Description: If you set a static IP, the network adapter will switch back to DCHP after the next reboot.

Workaround: This issue is caused by a MS update. A fix is planned in the monthly May QFE updates by Microsoft.

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

Description: On baseboards that only support FullSpeed USB customers can use the HighSpeed flag in the USB driver registry (http://developer.toradex.com/knowledge-base/usb-2.0-high-speed-%28480mbps%29 ). This feature is not supported yet on the Colibri and Apalis T30 modules.

Workaround: Add HighSpeed support to your baseboard. Check the reference designs (Iris Board, Evaluation Board) or apply the hardware patches described here (http://developer.toradex.com/knowledge-base/usb-2.0-high-speed-%28480mbps%29#Colibri_Evaluation_Board_V21_USB_20_Patch )

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: When updating the splash screen the settings oep and dispondelay are not automatically written from the WinCE registry to the bootloader config.

Workaround: Set the values manually in ss.oep and ss.dispondelay.

Description: On Apalis T30 modules V1.1A and later Ethernet is not working.

Workaround: Use latest image or on image 1.4 beta 1 download the patch from here: Win CE 7: http://developer.toradex.com/files/toradex-dev/uploads/media/Colibri/WinCE/Special/Toradex_ApalisT30_EthernetPatch_for_1_4_b1.zip . Windows Embedded Compact 2013: Get in contact with the support to get a driver.

Description: Removed shaders.dll from BSP. Shaders.dll is not used. This change only affects you if you build your own image with Silverlight support.

Workaround: Remove shaders from platform.bib manually.

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: 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.com/102481

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: Ethernet is not working when customers build their own image based on the Toradex BSP.

Workaround: Use the latest beta 1.4 beta 1 bis version from the download server, the missing files have been added there.

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

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

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: Some SD Memory cards are not shown in the file explorer, the initialization of the cards fails. This is due to the fact, that some cards need some longer to power up before the first communication can take place. To prevent this we have introduced a key "PowerUpDelay" in the SDIO driver. Default value is set to 200ms.

Workaround: After inserting the card toggle the Card Detect Pin manually or using the GPIOlib, after that card is mounted correctly. To get an updated version of the driver that fixes this issue already, get in contact with the support team.

Description: Some screens need a more accurate pixel clock. By default the display drivers uses the most efficent clock source. To make it more accurate the an other clock source has to be used. Therefore we have introduced a registry key forcePLLD in [HKLM\Software\Nvidia Corporation\NVDDI\LCD].

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: Power consumption has been reduced by up to 0.3 W in the latest image. - With DFS on EMC enabled power consumption can be reduced by up to 0.5 W (See issue 9380). - HDMI is disabled by default (Issue 9395). - Bootupstyle changed (Issue 9396).

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: Reading or writing to the FlashDisk while using the UpdateTool or any other direct flash access could lead to flash errors.

Workaround: Make sure the FlashDisk is not used while using the UpdateTool or any other direct flash access.

Description: Small issues with audio playback on T20 and T30. When playing two waves the same time or playing one wave immediately after the other sometimes parts of the wave get lost are are played twice. Some wave files had no output at all, only silence was played.

Description: Updated debug output: Replaced statement "...for Colibri built..." with "...for Tegra built...".

Description: The Colibri T20 does not resume when user touch display is used when the module is suspended.

Description: The RTCSync Tool is normally called as part of the boot-up of WinCE (part of init in registry). The SignalStarted API should be called when done if the tool was started as part of the init tools in the Registry. This allows customers to use the dependency feature of the registry init process.

Description: This Windows Embedded Compact 7 image contains Microsoft QFE Monthly Update April 2014.

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: The Bootloader and Image can now be backed up with the Updatetool. For production programming please still use the workarround described bellow as the Flashfile System, Registry and the Confiblock are not backed up.

Workaround: We have a workaround using the NVFlash tool: http://developer.toradex.com/knowledge-base/production-programming-for-tegra-modules

Description: Added support for new multimedia stack approach from Nvidia. This includes general multimedia support for T30 modules. Includes updates for OpenGL, OpenKode, OpenVG, OpenMax, DirectShow.

Description: GetDeviceCaps for the Windows recording device reports too many supported formats.

Workaround: Record at 44.1kHz 16bit only.

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

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

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

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: 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: 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: Sometimes some peaces of a sound are played again at the beginning when a new file was played later. This also lead to audio driver crashes when playing files again and again with a high frequency.

Workaround: Add sleep after playing sound before playing next file to prevent driver crashes.

Description: Add option to video player to play not in loop. Added the following params: - /l0 Not play in loop, - /l1 play in loop (default)

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: Audio recording randomly is not working. Recording did only work with 44100 SPS input data rate.

Description: A memory intensive application can cause the system to enter a thermal shutdown state as the RAM frequency will not be forced lower on high temperature limit (only CPU speed is forced lower)

Description: Update the documentation about thermal behavior of T20 and T30 modules

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

Description: - No changes to BSP, only GPIO Config Tool. DO not publish anything on this ticket

Description: Internal eMMC was running at half the clock speed it could.

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: Some modules don't boot after a software reset sometimes.

Description: Minor memory leak when repeatedly connecting / disconnecting the USB cable between module and a PC.

Workaround: -

Description: If you are running a a thraed with high priority (above 101) this can freeze the device. The device will not be able to handle any other interrupt.

Workaround: Prevent forcing high priority threads to core 1. Do not use high priority threads (above prio 101) whenever possible.

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

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: Additional delays in exception handling in OS image V2.0b4

Workaround: Build a custom OS image without Dr. Watson.

Description: OpenGL drawing artefacts in 16bpp mode

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

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: 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: This feature isn't tested. Composite with NTSC works.

Description: After several start/stop cycles start fails

Workaround: If possible avoid starting/stopping the graphs.

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: Web interface does not ask for password.

Workaround: If you are building your own BSP contact support and we will provide new DLL.

Description: Maintain two copies of the registry in case registry is corrupted.

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

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: 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: 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 that was in a release before November 2014, where this issue was not present.

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

Description: Load a special fail-safe recovery image if the main image is damaged

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: 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: On the Apalis or Colibri T30 when using an other debug (ser.port) output then the default one (Port 1) the system does not boot.

Workaround: This issue can be fixed by disabling the serial port you set in the bootloader ser.port bootloader configuration (see http://developer.toradex.com/knowledge-base/disable-drivers)

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

Workaround: Stop audio playback before suspending.

Description: When loading USBHCI3 first by purpose or also just by side effects like adding some additional registry keys, USB Hosts are not working at all.

Workaround: Fix the bootorder by setting [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\USBEHCI3] Order=33. This should fix the issue.

Description: The StorageMemory setting in the registry doesn't work. http://developer.toradex.com/knowledge-base/set-memory-division

Description: Suspend/Resume isn't supported yet on Colibri and Apalis T30.

Description: If using non default UART Pin muxings in some certain settings it is possible that the UART does not work as multiple PINs with the same alternate function are defined. The reason is that the bootloader may use other pins than the WinCE image.

Workaround: Customers can manually set the duplicated functions to GPIO in their application using the GPIOLib. Or use the same pin muxing in the bootloader as well as in the image (ser.pinmux in the bootloader).

Description: With disabled splash screen, not all display controllers are activated, also they are correctly set up in the registry.

Workaround: Use a black splashscreen instead of disabling the splashscreen at all. You can download the black splashscreen here: https://docs.toradex.com/102247-blacksplashscreen-125x125.zip

Description: The "PhysicalPageSize" registry setting for USB Hosts is not supported for Tegra module family.

Description: If JPEG encoding and decoding is done in hardware a data-abort can occur.

Workaround: Disable hardware JPEG encoder/decoder. SW encoding is the default setting in actual images. No action required.

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: Manual Dial Terminal is not available in CE6 / CE7
