WEC T20 / T30 BSP Release Details

Description: When trying to close a OpenGL application that was running for a long time (depending on the complexity of the 3d rendering this can vary from a few days to weeks) the system might freeze.

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: 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: Running a fullscreen OpenGL or Silverlight application with OpenGL support for very long time (~100 days) can lead to screen repainting out of sync which can result in a flickering screen.

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

Description: Unfortunately the SW could not deal with this new calibration value and was behaving incorrectly leading to crashes.

Description: If a subkey is is use the deletion of all other subkeys also fails

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

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

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 FlashDisk disappears on clicking "Backup" in the UpdateTool. This is due the fact, that the update Tool needs exclusive access to the FlashDisk. Reboot the system after that to get the FlashDisk back. Add a note about this in the backup dialogue.

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

Description: If you have more than one low-speed device on the same USB hub, data can get lost.

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

Description: The download bundle contains a config file that does not force the RAM to 533MHz any longer. If you flash the device with the Update Tool and you apply the CFG file or you use NVFlash the device will be setup with a RAM timing of 800MHz. If you only upgrade the image (NB0 file), the RAM timing will not change from the previous setting.

Workaround: Higher RAM timing can lead to some thermal issues. Add the following line to the CFG file in order to force the device running at 533Mhz RAM Timing (t30_emc_clk=533000).

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

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: 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: Depending on the Silicon Qualification Parameters stored in Nvidia Production Fuses we optimize operating Voltage limit to limit power consumption as much as possible.

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: Due to an issue in a Microsoft QFE update we had to revert the afd.dll to a previous version. The issue itself is documented under 29048. We use the following version of afd.dll CE6: 2016M10 WEC7: 2016M09 WEC2103: 2016M11

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

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

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

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

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

Description: Useful if debug serial port is not available or was not activated and debug output is needed. Debug files can be seen with this tool: http://developer.toradex.com/knowledge-base/debug-message-logger

Description: Implement temperature throttling for T30. Default settings (can be modified, see issue 7539). Configuration options are documented here https://developer1.toradex.com/knowledge-base/resource-manager-registry-settings#Temperature_Throttling_Configuration .

Description: If you type "c" in the bootloader menu to clear the registry, this has only an impact the following boot cycle. After rebooting, the old registry is there again. The registry should be cleared persistently instead. This issue affects images from 2.0beta 1 on.

Workaround: Save registry after booting with typing "c" (Clear Registry).

Description: Reject First Touch Event When Display Is Off to avoid wrong click actions when getting out of system idle.

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: 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: 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: 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: PCIe devices not always enumerated on PowerOn / HW ResetThis. This problem occurs only under special circumstances.

Description: Add some resource information into DLLs in order to improve tractability of drivers and prebuilt binaries.

Description: Reading fuse registers while a DMA transfer is going on freezes the system. Freezes often happend during restoring images using Update Tool 6.0 and later but in rare cases also during boot.

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: SYSGEN_COMMCTRL_ANIMATE and SYSGEN_DCOM have been added to CE 6 standard image and BSP.

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: Added new registry settings to control Power handling of an external Audio Amplifier (PowerDownTimeout, extAmpPin, extAmpPol, extAmpOnDelay, extAmpOffTimeout). Added event extAmpNotifyEvent that is triggered as well as GPIO that is toggled when codec gets enabled / disabled. See more details on the following developer website: http://developer.toradex.com/knowledge-base/audio-driver-registry-settings#Registry_Settings_For_Tegra_Only

Description: If you use -1 for the card detect pin (non removable card) the card will disappear after a suspend - resume cycle.

Workaround: Set a any GPIO pin as card detect pin and toggle it manually after resuming using the GPIO library.

Description: Up to image 1.4 the a hive based registry was stored in \FlashDisk . From this release on, the registry is stored in a new section of the persistent memory, which can not be accessed over the normal storage manager layer. In case you have been using the updatelib to save and clear the registry, you need to use an updated version of the updatelib. In order to support the new registry location you need to do the upgrade with the latest Update Tool and use the "Layout Config File" to do the re-partitioning of the Flash Disk.

Description: Due to a busy waiting after calling OEMSetRealTime() all threads have been blocked during 600us.

Description: Add support for 8bit SD/MMC devices. Use registry Key BusWidth=8 to force 8 bit configuration. See more details on http://developer.toradex.com/knowledge-base/colibri-t20-sd-card-interface . Currently 8 bit works in read only mode (see also follow up issue 17203)

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

Description: Updating certain modules from images 1.1 and older to images 1.3 and newer is not working properly. After updating the image and bootloader the module does not boot any longer. This is solved with Update Tool 6.0: https://docs.toradex.com/103231-tegra-update-tool.zip. First flash an emtpy .bct file and without rebooting do an image update using a .cfg file.

Description: The Media Player (Start->Programs->ColibriTools MediaPlayer) is not working under WEC 2013.

Workaround: Get in contact with the support team to get a player for WEC2013.

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: 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: The UpdateTool allows you to take a snapshot from an master module. This can be used for production programming later. See more details on the production programming documentation (http://developer.toradex.com/knowledge-base/production-programming-for-tegra-modules ) as well as on the Update Tool documentation (http://developer.toradex.com/knowledge-base/update-tool )

Description: Missing Catalog Item "Battery Support".

Workaround: Customers can build their own image with the feature enabled.

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]. See also http://developer.toradex.com/knowledge-base/display-driver-registry-settings#Settings_for_all_Colibri_and_Apalis_Modules .

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

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

Description: Add PCIe support for the Apalis T30 module.

Description: Fixed: The RTC time is not restored from an RTC other than M41T0. For the default RTC (M41T0) the tool is working properly. This issue affected Image versions V1.3b2 and V1.3b3.

Workaround: Contact support.arm@toradex.com to receive a patched RtcSync.exe tool.

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: Less carveout memory is used on Colibri and Apalis T30 modules. Default setting for carveout memory is now set to 2MB on T30 modules.

Description: Allow customization of AC97 audio codec register settings at boot time for Colibri T20 modules. We added a new registry key that allows customized initialization of the AC97 registers when powering up the codec. Documentation can be found here: http://developer.toradex.com/knowledge-base/audio-driver-registry-settings#Registry_Settings_For_Tegra_Only .

Description: Increased performance of second 3D instance of the T30. Approximately 2 times faster.

Description: DFS for EMC was added. There are now min / max keys in the DFS registry settings. The feature is not enabled by default in 1.3 beta 3. Set the key DfsEmcLowCornerKHz to 166MHz to enable it. See also http://developer.toradex.com/wiki-articles/resource-manager-registry-settings#Configuring_DFS_in_the_Registry.

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: 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: 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: 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 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: Since image version 1.3 beta 1 it could happen that OpenGL applications do not run any more. This is due to an updated shader compiler. This only happens if there already some precompiled shaders that have been used in a image before 1.3 beta 1.

Workaround: Delete the precompiled shaders (*.NVBV, *.NVBF) and restart your application.

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

Workaround: Record at 44.1kHz 16bit only.

Description: The number of DMA channels on Tegra modules is limited. This could affect interface functionality. E.g. if many serial ports are used audio might not work due to no free DMA channel. By default DMA is used only for RX. Check the registry key DmaSetting for other more (http://developer.toradex.com/knowledge-base/serial-port-registry-settings#Tegra_Family_Settings ).

Workaround:

Description: DFS (Dynamic Frequency Switching) uses the full frequency range at the moment. We added some registry keys to define the min and max frequency range in the registry. See description: http://developer.toradex.com/wiki-articles/resource-manager-registry-settings

Description: Slight performance optimization in Kernel and Drivers

Description: The system was hanging when power supply dropped below 3.08V but did not go below 2.0V.

Workaround: A full power cycle is necessary to get the module out of this state. In Image 1.3beta1 and later we have implemented a software option to either trigger a reset as soon as the voltage drops below 3.08V, or ignore that low-voltage condition at all. See http://developer.toradex.com/wiki-articles/resource-manager-registry-settings#Undervoltage_Lockout for more details. Both options are not effective during the system boot phase, from the time when the power supply rises above 3.2V, until the power management IC has been configured by the WinCE driver.

Description: The system time get's synced with an RTC running in the PMIC on the module. The PMIC was configured to use an RC-oscillator instead of the crystal. This could lead to inaccurate time reported by the RTC. The system gets synced every 24 hours with the RTC and therefore could see quite a jump of the time. We changed this in order to use the crystal. The time jumps are now limited to a minimum.

Description: Added support to RTCSync for external RTC M41T00S

Description: Added support for the RTC used in the PMIC on the T20 and T30 modules. However we still recommend to use an external RTC on the carrier board due to lower power consumption of such chips. More details here: http://developer.toradex.com/knowledge-base/rtcsync

Workaround: Use an external RTC on the carrier board as done e.g. on our Colibri Evaluation Board.

Description: Codec was not muted when no audio is played. This results in some background noise. The analog audio should now gets muted when no audio is played.

Workaround: Mute audio in user application when no audio is played.

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: RS485 support has to be added on application level. Add registry settings to support RTS Toggle on driver level as for the PXA family: http://developer.toradex.com/knowledge-base/rs485 .

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

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: 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: 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: Support UHS-I Mode for MMC1 interface

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: 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: 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: Default PS2 mouse port does not work reliable. Some keys are lost, default keyboard port works.

Description: Authentication enabled RTSP camera not supported

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

Description: Support DMA Flow Control By GPIO

Description: When dynamically switching is enabled and USB FN cable is removed, all USB devices are reloaded as well (e.g. Ethernet and USB HD disappear for a moment).

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: Drag and Drop of files doesn't work in the explorer/desktop on WEC2013.

Description: Some displays running in DE mode need LCD_HSYNC and LCD_VSYNC to be low all the time. Setting VSW=0, HSW=0, HSP=0, VSP=0 is not enough on T20 / T30.

Workaround: Set pins HSYNC and VSYNC to GPIO output low.

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: 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: 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: 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: 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: 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: The USB OTG registry setting CableDetectPol changes the cable detect polarity (see http://developer.toradex.com/knowledge-base/usb-client-driver-registry-settings#USB_Client_Cable_Detection_Tegra ). On default SODIMM pin 137 only the default polarity is supported.

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