Hi everyone
I want to thank everyone for helping with all of my problems so far, you
have been a great help.

Im trying to get a debug session with gdbserver over a serial connection on
my Xilinx ML410 using a uartlite set at Baud 115200.  When I issue the
command on the target "./gdbserver /dev/ttyUL1 test" I get this error:
Remote debugging using /dev/ttyUL1
readchar: Socet operation on non-socket
Remote Side has terminated connection.  GDBserver will reopen connection.

This error just repeats until I kill the process.  I know that gdbserver
works because debugging over TCP works fine.
Thanks for your help

Your kernel don't have kgdb support? then you need a debugger like bdi2000 to 
debug the kernel.

It sounds like he is trying to debug userspace.  Neither kgdb nor the
bdi2000 are the best tool for that.

Khollan; I haven't seen that problem before.  I don't know what could
be the issue there, but I'm not a gdbserver expert either.

Cheers,
