If TRACE32 cannot read the serial number of your debug probe, it usually indicates that the license stored in the probe is corrupted. In such cases, the serial number is displayed as C00000000000.

You may also see error messages such as:

• License damaged in debug cable, demo limited to 5 minutes

• Cannot read license from debug cable, demo limited to 5 minutes

Depending on the cause, the issue can sometimes be fixed remotely using a repair script. In other cases, the hardware may need to be sent in for repair.

Please report this issue to Lauterbach Support and include the following information:

• A system information report about your TRACE32 configuration:
