Stefaan,

I doubt there's a description of it, but I recall that the delta was _very_ minor. Here's what you can do to determine the difference between SREC and .flash.

  1. Convert the .flash to binary using objcopy.

  2. Create an SREC from that binary, again using objcopy. (format it to closely match the original .flash).

  3. Compare the two SREC files.

I think there's only 1 or 2 extra SRecords, one of which is a timestamp...I believe.

[UPDATE: You do realize that you can program an SREC directly to the flash using nios2-flash-programmer, right?]

Cheers,
