Let's assume that you built and did burn the RedBoot image for target.
Setup windows hyperterm as 38400,n,8,1. Open it for your serial port and
reset a board. What do you see then? Do you see Redboot's prompt? If you
do... Copy and paste RedBoot's welcome screen and send it. It's just
interesting, What RAM limits: %{FREEMEMLO}, %{FREEMEMLO} you got? Try to
press '+' in hypertem. You have to see a GDB packet. Does RedBoot reply
on '+' character? What do you see?

GDB loads ELF images!
And again, read RedBoot's guide
