We have an issue using WINCE 6 under AM3703. : It just appears once for now.
When analizing the dump file with WinDBG, this happened in mdd.c file in the EvaluateEventFlag function.
The issue seems to appear when calling EnterCriticalSection(&(pOpenHead->CommEvents.EventCS));
Here is the result in WinDBG:
APP: nk.exeBUGCHECK_STR: APPLICATION_FAULT_NULL_POINTER_READ_ZEROED_STACKPRIMARY_PROBLEM_CLASS: NULL_POINTER_READDEFAULT_BUCKET_ID: NULL_POINTER_READLAST_CONTROL_TRANSFER: from c0893314 to c08925a0STACK_TEXT: d056fe24 c0893314 : 01f40003 00000000 01f40003 ffffcbac : omap_uart+0x25a0d056fe40 c0893384 : 01f40003 00000000 01f40003 ffffcbac : omap_uart+0x3314d056fe7c 00000000 : 01f40003 00000000 01f40003 ffffcbac : omap_uart+0x3384SYMBOL_STACK_INDEX: 0SYMBOL_NAME: omap_uart+25a0FOLLOWUP_NAME: MachineOwnerMODULE_NAME: omap_uartIMAGE_NAME: omap_uart.dllDEBUG_FLR_IMAGE_TIMESTAMP: 4f95123fSTACK_COMMAND: ~45s ; kbFAILURE_BUCKET_ID: NULL_POINTER_READ_c0000005_omap_uart.dll!UnknownBUCKET_ID: ARM_APPLICATION_FAULT_NULL_POINTER_READ_ZEROED_STACK_omap_uart+25
I don"t know what hapened , what can we do to avoid this error?
The best way to debug this issue is build a Debug version of your OSDesign and keeep breakpoints in all entry points of MDD functions such as COM_XXX.
Also place breakpoints in PDD and do a step debugging.
