Hi,

I start the gdb stub on the target by:
        gdbstart -s 38400 -t /dev/ttyS0
and start the gdb on the development box by:
        gdb vmlinux
        gdb)
        gdb) set remotebaud 38400
        gdb) target remote my-server-ipaddr:port  #note, the port I put 
here is the serial port# on the server,
                                                #not L4 port, correct?
Now I only get error message:
        ignoring packet error, continuing....

If I replace the console server by a direct serial cable for the above 2 
boxes,
and use 'target remote /dev/ttyS0' instead. Everything works fine. So I know
except the serial connection, the rest configs are correct.

Could anybody correct me where I did wrongly ?

Thanks
