Please help resolve "Instruction fetch exception"

Dear Experts :

                                 My code has undergone migration changes from dsp bios to sys bios. While running the code in CCS v5, i get the following instruction fetch error copied below. While looking through some posts on similar topic , i read that i had to check the register B3 and the address of NRP. I checked using the disassembly tab and i see that NRP address range doesnt exist in the*.map file and the address in itself points to NOP. B3 register also looks suspicious with 0x0. What couldbe the problem?
