Hi everyone,
Am trying to load a simple hello world program after loading the
Redboot image into my LPCE2214 target(host is windows/cygwin).
The redboot image seems to be working fine.am able to ping the board
from the host and also i can ping the host from the target board
(from redboot prompt in terminal app). And here are the some redboot
command outputs for ref..

I have loaded this hello.sre file using the folowing command from
windows hyperterminal redboot promt.
