    I understand most of the parts, but only stuck at base address. I don't know
    what to choose. I am currently using 0x378, but somehow it corrupted my boot
    loader at that address. leave my board unbootable. As in Strong ARM, there is
    no parallel port at all, I am using its general purpose IO pins to simulate
    the behavior. And Accessing those PINs are through registers, I am not sure
    what are the requirement for the base address. It seems I cannot choose
    randomly.

    I attached my implementation files for your advice.
