Guys:


I have a bdi2000, too!  Just got it yesterday... :^)

I don't know what runtime library you're using, but if you step
through exit() most of the time it terminates in an infinite loop.

What needs to happen instead is something like a BKGD instruction (I'm
using cpu32, in case you couldn't tell), that forces the chip back
into debug mode.  The bdi2000 should catch that and tell gdb that the
target has halted.

As to the "program terminated normally" message, that's going to
depend on how the bdi2000 interprets the occurrence of the BKGD event.
And that, along with whatever they (don't seem to) provide for console
output facilities, is up to Abatron.


HTH,
