Hi List,
I am experiencing a Data Abort inside function 'GetSectionFromAnyFv' in file 'DxeServicesLib.c' on my ARMv7 UEFI platform.
To debug the same I added some print messages like:
/* Added for debugging */ CHAR8 Buffer1[100]; UINTN CharCount; CharCount = AsciiSPrint (Buffer1,sizeof (Buffer1),"Inside Func\n\r"); SerialPortWrite ((UINT8 *) Buffer1, CharCount);
And also something like: SerialPrint ("Inside Func\n\r");
I have included: #include <Library/PrintLib.h> #include <Library/SerialPortLib.h>
and defined:
#define SerialPrint(txt) SerialPortWrite ((UINT8*)(txt), AsciiStrLen(txt)+1);
I still cannot see any debug prints on the UART (placed right after the entry point of 'GetSectionFromAnyFv' function). Debugger (DS-5) suggests that the crash is inside 'GetSectionFromAnyFv' itself.
I get the UEFI firmware <version xx built at xx on xx) and Data Abort Exception PC at xx prints on the console, but no prints from 'DxeServicesLib.c'
Any pointers to what I may be missing here.
Regards, Bhupesh
