T20: WinCE7 Crash during boot

andreas · May 8, 2019, 3:14pm

Hello

I built my own image upon BSP 2.2. Before we were still on BSP version 1.4. There I could build my own BSP without problem and it booted normaly.

Using now BSP V2.2 I’m no longer able to compile a bootable image. It always crashes during the loading of the filesystem. The output on the serial output shows the following:

I really don’t see where I’m missing something.

Thanks for any help.

Dear @andreas

Thank you for the detailed description. There are two possible reasons for the issue:

Nvidia flash partitions
Between V1.4 and V2.2 we moved the registry from the filesystem into a separate flash partition. By default this partition does not exist and can lead to various boot problems.
Try to flash our standard V2.2 image using either the Update Tool or NvFlash - use the *.cfg file to do the update. This way the additional partition will be generated automatically.
After this debug your customized OS.
Filesys.dll
We patched the filesys.dll, the patched version is part of our workspace. Please make sure you include this patched version, not the Msft default one.

Regards, Andy

Thanks for your answer.

I finally got it running. I had to change several things:

Add the filesys_hive_based_registry.dll and the filesys_ram_based_registry.dll

Add the new environment variables to the pbxml file so it looks like that now as in your workspace:

<StringDictionary Name="EnvironmentVariables">
    <Entry Name="sysgen_pcl">1</Entry>
    <Entry Name="sysgen_printing">1</Entry>
    <Entry Name="sysgen_ramdisk">1</Entry>
    <Entry Name="os_config">COMPLETE</Entry>
    <Entry Name="sysgen_usb_printing">1</Entry>
    <Entry Name="prj_enable_fsreghive">
    </Entry>
    <Entry Name="bsp_load_async">1</Entry>
    <Entry Name="bsp_load_filter">1</Entry>
</StringDictionary>

Add these BspFeatures in the pbxml file:

<FeatureCollection Name="BspFeatures" EnforceUniqueItems="True">
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_NV_BACKLIGHT" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_NV_ODM" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_NV_DISPLAY" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_NV_AUDIO" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_NV_RM" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_NV_SDIO" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_NV_UART" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_NV_NAND" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_NV_EMMC" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_NV_FSSTREAM" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_NV_USBF" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_NV_USBH" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_NV_USBOTG" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_TDX_LAUNCHER" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_TDX_RTCSYNC" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_TDX_UPDATE" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_TDX_KEYBOARD" />
    <Feature Name="Item" CatalogItemId="Item:Toradex:BSP_TDX_TOUCH" />
</FeatureCollection>

Thanks.
