Issue #StatusSubjectModuleSubsystemWinCE OS

V4.6 (Release date: 2018-03-08)
The version 4.6 contains only one change in the bootloader, see issue #34332 below for details. The change is related to initial production programming at the factory only and doesn't affect normal usage. The WinCE image and BSP were not changed and therefore not rebuilt for 4.6. They stay at 4.5. Customers can continue to use their tested bootloader and image version as the issue fixed in 4.6 bootloader isn't critical and doesn't have any affect in normal boot mode.
WC-1230FixedBadBlock detection during initial production programming takes too longColibri PXA320, Colibri PXA310, Colibri PXA300 XT, Colibri PXA300BootloaderCE5, CE6

Description: The bootloader contains code which is used during initial programming at the factory only. In this code there was a bug which could have lead to timeouts during production depending on the content of the flashes coming from the flash manufacturer. This bug was fixed in the bootloader 4.6. This change doesn't have any impact on normal boot behavior and only changed the behavior during a special test mode during initial programming at the manufacturer.

V4.5 (Release date: 2015-06-19)
- WinCE 5 Updates: Installed Microsoft CE5 Updates until 2014M07
- WinCE 6 Updates: Installed Microsoft CE6 Updates until 2014M07
WC-1217FixedMAC Address and HW Version get overwritten by the UpdateTool in BSP V4.4 on Colibri PXA3xx modulesColibri PXA320, Colibri PXA310, Colibri PXA300 XT, Colibri PXA300ConfigBlockCE5, CE6

Description: A bug in Kernel V4.4 leads to overwritten MAC address and hardware version settings in the config block when using the UpdateTool to restore the config block. This is normally done, if you use a complete Flash backup to clone the Colibri module SW configuration in production process. Having modules with the same MAC address is only a problem if you are using these devices in the same Ethernet network.

Workaround: The following article describes the problem in detail and provides various solutions: http://developer.toradex.com/knowledge-base/colibri-pxa3xx-bsp-v4-4-update-tool-issue

V4.4 (Release date: 2015-04-14)

Description: When using Mobile Device Center under Win 8 to directly write to the SDCard attached to a Colibri PXA using Win CE5 corrupts the written file.

Workaround: Copy the data to either the FlashDisk or ObjectStore (a RAM folder e.g. Temp) and copy it then to the SDCard using WinCE 5.

WC-1265Known IssueDelayed Serial Transmit CompletionColibri PXA320, Colibri PXA310, Colibri PXA270, Colibri PXA300 XT, Colibri PXA300UARTCE5, CE6

Description: The serial transmit thread can be interrupted by a thread with the same interrupt priority. This could lead to delayed transmit completion. This normally only affects customers which are using e.g. a RTS toggle function for RS-485 communication as the RTS signal may take several 10ms until it toggles back after sending data.

Workaround: Increase the priority of the sending thread.

WC-1259Known IssueUART 3.6Mbps Freezes PXA300/PXA310Colibri PXA310, Colibri PXA300 XT, Colibri PXA300UARTCE5, CE6

Workaround: Change the timezone prior to using RemoteAdmin

WC-1235Known IssueNAND was not formated as TexFATColibri PXA310, Colibri PXA270WinCE FeatureCE6

Description: Bug in code prevented system to be auto formatted as TexFAT. This could lead to data loss.

Workaround: Add this registry keys -> [HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MSFlash\EXFAT] "FormatExFat"=dword:1 "FormatTFat"=dword:1 "DisableAutoScan"=dword:1 After this user should reformat NAND using settings TFAT and exFAT

WC-1233Known IssueBitflip in nand spare area will corrupt file systemColibri PXA320, Colibri PXA310, Colibri PXA300 XT, Colibri PXA300FlashCE5, CE6

Description: The spare area is used to store meta data for the Flash Disk. However, the spare are isn't ECC protected. A bit flip can cause data loss on the Flash Disk. The SLC flash used on Colibri PXA modules is really reliable and we didn't see problems so far.

WC-1232Feature RequestHarmonize FlashDisk settingsColibri PXA320, Colibri PXA310, Colibri PXA270, Colibri PXA300 XT, Colibri PXA300CE6

Description: When using RTSToggleAlwaysOn = 1 and RTS_Pol = 1 (e.g. for RS485) the RTS signal is active (1) when booting until the first data is sent sent. From then on it behaves as expected (only active when sending). The behavior is as expected when using RTS_Pol = 0, but of course with inverted levels.

WC-1211Known IssueConfig block command line: clearing a section hangsColibri PXA320Bootloader

Description: clearing a config block section from the bootloader can freeze the bootloader.

Workaround: after clearing the section, wait 3 seconds, then reset the system.
