Re: Using GDB with M32R MSA2000 Board

[Fernando Nasser <fnasser@redhat.com>]

Just to get a clearer error message, use GDB in command mode:

gdb -x -nw <your program>
...
(gdb) set remotebaud 9600
(gdb) target mon2000 /dev/com1

I don't know much about the mon2000 target.  If it has a log
facility you may try setting it on.
