[ECOS] RedBoot: Checksum failure while loading from ext2?

[Dmitry Ryzhkov]

Does anybody know what's difference in loading of the same file using ttyS0 
and ext2fs - file?

If i issue 
RedBoot>lo -c 0 -m x
it works OK (I give hello.srec from host's side)

Trying with the same file
RedBoot>lo -m disk hda2:myhome/hello.srec
causes:
*** Warning! Checksum failure - Addr: 012FED FF <> 00
and looks like stopped.

What's wrong?

Thanks for your help!
