Alberto,

The .flash files are really just SREC (SRecords), so their size is not what matters. It's the binary content they contain that really matters.

Fortunately, there's an easy solution. binutils, included with the Nios II toolchain, has a utility called "size" which can determine the binary size of an SREC. Just type...

Adding these together will give you the total size.

Cheers,
