Hi Phil

Thanks for the help. I can now use ddd to debug a program which is running
on the Gumstix board.
I use the HWUART (ttyS3). It did almost work in the first place, but I did
rebuild the tools a couple of times and GDB is still complaining about the
uclib library so I will write within the next few days with a description of
how to build the tools.
To Robert: Yes it should be possible to use the USB connection when
debugging. If you start the USB network it should be possible to start
gdbserver with host:port instead of ttyXX.

Best Regards
Benny
