As fine as I know, other options are available, but they are essentially
more expensive. For example, you may consider Abatron BDI2000 box,
http://www.abatron.ch. Abatron has an option when gdb debugging protocol
supported over ethernet, and they support Coldfire processors. I guess,
gdb "from the box" can communicate with this debugger (but I have not
tried this, it's just a theory).
