Try turning on remote GDB debugging:
  (gdb) set remotedebug 1
  (gdb) tar rem /dev/ttyS0

A couple of notes:
 * Make sure of your baud rate before trying the connect.  For example,
   (gdb) set remotebaud 38400
 * The syntax of setting the remote debug flag is a little different
   in the latest GDB snapshots, but it is similar so I'm sure you
   can decipher it.
