Use the ICD Test Interface module to verify that the debugger is
functioning correctly (ICD Test Interface Module).
There may be a problem programming in general. As a test, switch to
Run mode using the
icon and program the target with the simplest application
possible (for example, a program to blink an LED). If the program will not run, then you
know that something is wrong with the target setup.
It is possible that the target device has been damaged in some way
(for example, over current). Development environments are notoriously hostile to
components. Consider trying another target board.
Review debugger setup to ensure proper application setup. For more
information, see Operation.
Your program speed may be set too high
for your circuit. In MPLAB X
IDE, go to File >
Project Properties, select ICD4 in Categories, then
Program Options, Program Speed and select a slower speed from the
drop-down menu. The default is Normal (see figure below).Figure 5-1. Program Speed Option
There may be certain situations where
the debugger is not operating properly and firmware may need to be downloaded or the
debugger needs to be reprogrammed. See the following sections to determine additional
actions.
