Problem with OSBDM : Continuous "Speed Change detected" message

Hello everybody,

We are two students who want to use the OSBDM for our university projects. So we designed two OSBDM which currently have a problem. The error we encounter is the same for the two BDMs.

The USB part seems to work well. The BDM is detected by Windows and Codewarrior and has been flashed in ICP mode without problems.

The target we want to debug works well in debug mode. We tested it with an other OSBDM and everything works perfectly. We even tried to force the target in debug mode when starting it up but this don't change anything.

When we start the debugger in CW, we have following errors :





The "command" window gives following output (the last line (speed change detected) repeats indefintly until we reset the OSBDM) :

Code:

We tried to upload a empty project, but the code don't get uploaded sine the original program on the target remains there.

We have tested almost everything we could imagine. If somebody had an idea it would be really great.

Thanks in advance.
