Yes.

I converted the .sof file to be programmed on the EPCS flash. This looks to be good.

I converted the .elf file to be programmed on CFI FLash. This also seems good, and verification comes back with a successful result.

I have pointed Reset vector to CFI flash and Exception vector to op-chip memory.

I am thinking the problem may have something to do with the code running much quicker in RAM than it does in Flash? I thought I read that the boot process automatically takes the Code from Flash and puts it into RAM before its starts to execute the program? Is this true, Do i need to do anything to make this happen?
