I must be having similar problems to Scott. I tried doing ctrl-z after
uploading and (c)ontinuing redboot from gdb. When minicom comes
up I see nothing. I assume you are doing 'minicom -o' which skips past
modem initialization. Instead of ctrl-z should I completely exit gdb?
What kind of feedback are you supposed to get from the EB40 to confirm
you are talking to RedBoot? The 'RedBoot>' prompt?
