Re: Serial support for arm board


That would be great, however, I am assuming Redboot is
a proper subset of Ecos and that I would have to
install Ecos on the board, no? If I screw up the boot
loader install then I am going to have even bigger
problems.
 Or can I just link in the appropriate libs and run
from Redboot?
