We would only use that code for examples of how to bolt in
the bottom end drivers.  We would roll out our own os/scheduler,
a little * code and drivers.

I have not found a data sheet for the 1001 yet, but I did look at the 1050.
Great looking chip.  Just a few questions.

Any idea how much it cost?

It does have a jtag debug interface.
Do you know of any gui debuggers running on linux for this chip?

We really need a nice friendly debug environment to make it as easy
to write/load/debug code as doing it for linux.
