The speed issue's not a limitation with the parallel converter apparently,
but
a problem with Codewarrior. I'm told that Metrowerks are being hassled
to
speed it up! I hope they hurry up! ;-)
The one breakpoint limitation is down to the DSP itself. It only has the
capability to do one breakpoint in its hardware when running out of flash.
You can set, I think, three when running out of external RAM with the demo
boards.

How slow
is slow for run and stop of program ? The limit of one breakpoint is for
when you are using hardware breakpoints. This type of breakpoint is what you
need to use when debugging from flash and uses the hardware breakpoint features
of the once port and has nothing to do with the command converter connection.
You can get an unlimited number of breakpoints if you use software breakpoints,
but you will have to run from RAM.
Also you can instrument your code with
debug statements using the inline assembler and get more 'breakpoints'
when running from flash but you will not be able to turn them on and off.
Thanks.
