It's all coming back to me now....

You did remember to issue 'c' in gdb right?  That starts redboot
running on the board.  Then you have to shell-out of gdb by doing
a ctrl-z so it will release the serial port so minicom can use it.

Remember to start minicom using 'minicom -o'  to bypass any serial
port initialization.  Be sure minicom is setup to use 8N1 @38400.
Hit enter a couple times and the redboot prompt should appear.

Another EB40A issue I had was the clock speed.  That is all fixed
in the patches I submitted.  Hopefully those will get applied to cvs
soon.  The EB40 should be fine.
