But, I think the binary dump/restore function still needs to be there: 1) I'd like to be able to dump data in a format understood by objcopy. That way, you can convert it to specific formats needed by other tools (e.g. RPOM programmer), link it into another program, etc. 2) Redirecting output doesn't provide a way to load a chunk from disk back to target memory. I don't need to do this nearly as often, but it would occasionally be handy. -- Grant Edwards grante@visi.com
