Windows CE Loading problem on OMAP

Hi,

We are using Windows CE 6.0 based BSP for TI OMAP based SOM board which we have procured from a vendor in TIWAN.The BSP has been given by the Tiwanese company, but there is no support for BSP.

 The system has 7”inch TFT with touch panel. The OS is in the FLASH which is on SOM and the application is run from the SD card. The application 's data base is also on the SD card.

The changes made to the BSP are removal of explorer and added a functionality to launch our dedicated application on Boot.

The system boots with our company logo and then the application is launched.
Our application does not write any data to the registry, all the data is stored on the SD card.

Its all working fine on multiple systems but on a couple of instruments we have received problem stating that,

the display goes blank after the Logo. The Serial Debug output is as follows

NK Image Loaded
Launch Windows CE image by Jumping to 0x80001000....
Windows CE Kernal for ARM(Thumb Enabled) built.......

----High Performance Freq os 32768Hz

OEMInit (Deinitialize serial debug)

When we reprogram the OS to the SOM's Flash the problem is resolved.

How do I pinpoint where the OS is failing.

thanks

in advance

Regards

Prasanna
