D.1. Connecting the baseboard to the PCI enclosure

This section describes how to configure the PCI backplane and connect the baseboard to the PCI enclosure.

To use the baseboard with the PCI backplane and enclosure:

  1. Configure the baseboard by installing Core Tiles as described in Setting up the baseboard.

    Caution

    Do not connect power to the baseboard yet.

  2. Connect a JTAG debugger (such as Multi-ICE) to the board, or use the USB debug port. See Connecting JTAG debugging equipment.

    Note

    The JTAG connection on the baseboard does not connect to the PCI backplane. Use the baseboard JTAG for debugging applications.

    There is also a JTAG socket on the PCI backplane. Only use this connector if you are reprogramming the PAL on the PCI backplane.

  3. Set the configuration switches on the PCI backplane. See Setting the backplane configuration switches.

  4. If you are using an external display:

    • For VGA displays, connect the cable from the display to the VGA connector on the baseboard.

      Note

      If you are using a VGA card in the PCI bus, connect the VGA display to the VGA connector on the PCI card. You must provide the interface code for the PCI display card.

    • For CLCD displays, connect the CLCD expansion board cable to the baseboard and if necessary, connect the display interface cable from the expansion board to the CLCD display. See Appendix C LCD Kits.

  5. Slide the baseboard into the PCI connector on the side of the enclosure. Figure D.1 illustrates an baseboard mounted in the PCI backplane in the supplied enclosure.

  6. Apply power to the PCI enclosure.

    Caution

    Do not connect power to the screw terminals or to the power socket on the baseboard.

  7. Execute the initialization code to setup the PCI address-mapping registers, see PCI controller.

Note

The PCI card INTA# is the interrupt output for a single-function device. INTB#, INTC# and INTD# are only used for multi-function devices.

Figure D.2 shows the interrupt routing. Signals are swapped around to enable simultaneous interrupts.
