I have The evaluation board DSP56F807 EVM-1 with codewarrior 5.0. The communication between the computer and the evaluation board is very slow when I want to run or stop the program. Moreover I can put only on breakpoint in the program. Can someone tell me if there is the same limitations with the parallel port command converter "DSPCOMMPARALLEL" Thanks. |

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.

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. |
