    Navneet,

    From the description it look like CPU is getting into ITRAP which could happen if program did not get loaded properly or code is getting overwritten due to stack overflow or incorrect coding. Can you step through assembly code to see when it jumps to BOOTROM and if that instruction is same before running the code and after running the code?

    Regards,
