Hi Sean,

I need a little help in attaching the debugger.
My board is connected to the host only through one serial cable which I use
for console terminal.
Can we attach a debugger through the same serial connection? coz my setup
does not yet
have an ethernet driver.. yet.

If yes, can you tell me how to or point me to the link with instructions?

Thanks,
Jayanth
