Re: [ECOS] AT91EB40 and RedBoot

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?
