Perhaps the message is the initial checksum error reported when no Flash
Image System has been created yet. If you do a "fis init" it may just go
away.

The best thing to do is follow the generic instructions for rebuilding
redboot in the on-line RedBoot user's guide at
http://sources.redhat.com/ecos/docs-latest/

Unfortunately there is no edb7xxx-specific section yet (Hi Gary :)), but it
should just be a case of following the generic instructions, bearing in
mind that there are configuration import files at
hal/arm/edb7xxx/current/misc which should be used.
