Flash Programmer Error

Hi,

I'm currently using the Flash Programmer included in the Nios II SBD Tools for Eclipse. When I try to generate and program flash files to my DE2-115 board from a .elf file (the code already works in 'Run' mode), I get error code 4: program failed at offset 0.

I've seen a couple of other threads saying to set a flash offset of 0x20000, but this doesn't work when you're generating from .elf files.

Any thoughts on this problem?
