8.2.6 Debug Failure Acons
The MPLAB ICD 5 In-Circuit Debugger was unable to perform a debugging operation. There are
numerous reasons why this might occur. See section Troubleshooting.
8.2.7 Internal Error Acons
Internal errors are not expected nor should happen. They are used for internal Microchip
development.
The most likely cause is a corrupted installation ( Corrupted Installation Actions).
Another likely cause is exhausted system resources:
1. Try rebooting your system to free up memory.
2. Make sure you have a reasonable amount of free space on your hard drive (and that it is not
overly fragmented).
If the problem persists, contact Microchip Support.
