I am trying to get a PIC18F2580 with some test code in it to perform and function in a breadboard. The programed CPU will work fine in my evaluation board, but when I put it in a a breadboard and connect the PIC to power/ground and put a 20 Mhz crystal it will not run as expected. We also tied the reset pin high. The weird thing about it is when I scope the crystal all I see is a DC voltage of 2.5V, with NO AC component, when I scope the crystal in my eval board I see a perfect 20Mhz sine wave. I have replaced the crystal and still results are the same. Ideas?
