Red Hat has ported eCos to the VR4300 architecture (specifically the VRC4373
eval board), and is available now under the early access program.

Note that Red Hat will shortly be releasing a new public version of eCos.
While we cannot release specific details at this time, it would be good for
you to look at this when it is released.

Try using "set remotedebug 1" to check what traffic is actually going in and
out. Also be sure that no other programs are using the com port.

You could also try setting the endianness of the file by hand (eg. "set
endian little") in case that's the problem.
