The C's come every 5 seconds, roughly. If the problem was in Redboot wouldn't 
that mean that I wouldn't be able to upload using hyperterminal? v850-elf-gdb 
also seems to work as far as my testing goes.

I have connected to both serial ports, the debug and the serial access port. I 
can't see any output in either of them. There is nothing wrong with my boot 
script because when I type reset the boot script works but on a hard reset 
the program bombs.
