Analysis Probe Problems
This section lists problems that you might encounter when using an
analysis probe. If the solutions suggested here do not correct the
problem, you may have a damaged analysis probe. Contact your local
Hewlett-Packard Sales Office if you need further assistance.
Target system will not boot up
If the target system will not boot up after connecting the analysis
probe, the microcontroller (if socketed) or the analysis probe may not
be installed properly, or they may not be making electrical contact.
❏ Ensure that you are following the correct power-on sequence for the
analysis probe and target system.
1 Power up the analyzer and analysis probe.
2 Power up the target system.
If you power up the target system before you power up the analysis
probe, interface circuitry in the analysis probe may latch up and
prevent proper target system operation.
❏ Verify that the microcontroller and the analysis probe are properly rotated
and aligned, so that the index pin on the microcontroller (pin A1) matches
the index pin on the analysis probe.
❏ Verify that the microcontroller and the analysis probe are securely inserted
into their respective sockets.
❏ Verify that the logic analyzer cables are in the proper sockets of the
analysis probe and are firmly inserted.
