I was able to make some progress on this, but I'm sure there are some major
problems with the configuration (it seems a lot has changed since I made the
previous configuration file for build 717!)
I'm a bit lost, though, why the board can not reset (it times out, see below),
and the command "arm7_9 force_hw_bkpts enable" is in the documentation as valid,
so I don't really understand why it's throwing an exception.
For reference sake, here is the output when I start the debugging process. I'll
include my config files afterwards:
