At this point things are probably already broken, so I don't
know if the messages below mean much. ADP (the protocol used
by Angel) has a _lot_ of state to it, and restting the target
without restarting GDB never works (at least not for me).
Restarting GDB without resetting the target usually works, but
not always.

1) Reset the board.
2) Start GDB.
3) Do the command "maint rdilogen on"
4) Do the command "target rdi com1"
5) Exit GDB

That should create a file named "rdi.log" with the initial ADP
packets logged to it. Post that file and we'll see what we can
see.
