Hi Sergei,

Support for loading from fileio is present, but hiding; I think what you
found was the old code. It really lives in fs/fileio.c, switched on by the
option CYGPKG_REDBOOT_FILEIO.
All you should need to do is add CYGPKG_IO_FILEIO to your config, and
resolve any conflicts, before you build RedBoot. Then, the syntax "load -m
fileio /some/file" is what you're looking for.
It all Just Worked for me when I tried it out a few months ago. (I was using
a YAFFS filesystem and my NAND library, but there's no reason why jffs2
shouldn't work.)
