You want to use the same device that Fernando suggested in the previous
message.  Before you issue the "target remote" command, say:

(gdb) set debug remote 2

Then you will get a trace of all the messages flowing between you and your
stub.  You can see if you ever connect, or if there is some errors in the
initial handshake that are causing the hang.

The gdb info file has a section on the remote protocol, which will help you
understand the traffic you are watching.
