This should work, but 7.1 needs to be:
  ecosconfig new at91 redboot

Otherwise, you end up with the default configuration and a .ecm
file which tries to turn it into a RedBoot one which doesn't
work well at all.

Hint: you *really* should be using the CVS tree and not the old
2.0 "release" which is now *many* [in truth, nearly 5!] years old.
