I have tried this method. I connected hyperterminal and tried to get output
from the program. I load the program into RAM using EPPC-bug firmware and
then enter the GO command to get it to execute the downloaded ecos code.
The first line in my cyg_user_start is a printf. I tried changing this to
diag_printf and even using cyg_io_write using the /dev/ser1 (SMC1 port).
However, I still cannot get output from the target MBX board.
Do you have an .ecc configuration that you were able to get running without
GDB on a target MBX board?
Do you know what else I should enable/disable in the ecos configuration that
I might be overlooking?

You need to do it from a terminal as GDB does not allow you to send
out data (well, you could use the maintenance command if you really
want to go through GDB).
As for the target side, launch a thread which opens /dev/ser0 or
similar and read in characters. Parse them whichever way you want.
If you want a line-based interface you could use /dev/tty0 instead (I
think).
