Also, how are you programming your Flash ROM? Try downloading it and reading the memory locations with MPC8bug (normally MPC8bug puts the Flash up at 0x02800100), then power off for a minute or two, then reset the board normally through MPC8bug and read the memory locations again. It almost sounds like your Flash isn't getting programmed at all... Do an mdi at 0x02800100 to see if your code is properly getting programmed. I've got a feeling that I might know what's going on.
