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 emulator 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 ICE4 in
