The ".flash" file is basically an SREC (SRecord). What you want to do is parse the binary data from the SREC (containing either SOF or ELF content) and program THAT into flash.

Alternately, you could use objcopy to convert the SREC to binary format on your PC...avoiding the SREC parsing by Nios II.
