sof2flash --epcs --input=project.sof --output=project.flash

elf2flash --epcs after=prokect.flash --input=firmware.elf --output=firmware.flash

cat project.flash firmware.flash > hwsw.flash

Shouldnt nios2-elf-objcopy fix this? Or am I missing something?

I suspect the code ends up in the wrong place :-/
