·I know this maybe a stupid question but I can't seem to find the issue with my board.· There is no orientation with the crystal is there?
None that I ever heard of anyway.

    steprog,

    There is no orientation for the crystal. It is a passive bi-directional device.

    No. Crystals are ambidextrous. Or is that ambipinderous?

    Im having an interesting problem. I got a talks and walks and does everything ok but for some reason. The IO pins don't do as they are told. This is a custom board and another strangeness is the PASD software wouldn't work on it, but would on a protoboard I have. Anyone with any ideals.

    We need some more information: a circuit diagram, PCB layout, picture of the board, specific nature of the problem...
    "Pins don't do as they are told" is kind of vague.
