Solving Problems

If you have problems with the HP processor probe, your first task is to
determine the source of the problem. Problems may originate in any
of the following places:

•

The HP processor probe itself

•

The connection between the HP processor probe and the target
system

•

The target system

•

The connection between the third party debugger and the HP
processor probe

You can use two means to determine the source of the problem:

•

The status lights on the HP processor probe

•

The HP processor probe "performance verification" tests
