10.3.5 USB Port Communication Error Actions
The problem is most likely caused by a faulty or non-existent communications port.
1. Reconnect to the MPLAB REAL ICE in-circuit emulator
2. Make sure the emulator is physically connected to the PC on the appropriate
USB port.
3. Make sure the appropriate USB port has been selected in the emulator Settings.
4. Make sure the USB port is not in use by another device.
5. If using a USB hub, make sure it is powered.
6. Make sure the USB drivers are loaded.
10.3.6 Debug Failure Actions
The MPLAB REAL ICE in-circuit emulator was unable to perform a debugging
operation. There are numerous reasons why this might occur. See Chapter
8. “Troubleshooting First Steps”.
10.3.7 Internal Error Actions
Internal errors are unexpected and should not happen. They are primarily used for
internal Microchip development.
The most likely cause is a corrupted installation (Section 10.3.4 “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.
