Bringing up the Board
The MVME162P2 comes with MVME162Bug firmware installed. For the
firmware to operate properly with the board, you must follow the steps
below.
!
Caution
Inserting or removing boards with power applied may damage board
components.
Turn all equipment power OFF. Refer to MVME162P2 Configuration on
page 1-5 and verify that jumpers and switches are configured as necessary
for your particular application.
1. Configuration switch S4 on the MVME162P2 contains eight
segments, which all affect the operation of the firmware. They are
read as a register (at location $FFF4202C) in the Petra MC2 sector.
(The MVME1X2P2 VME Embedded Controller Programmer’s
Reference Guide has additional information on the Petra MC2
emulation.) The bit values are read as a 0 when the corresponding
switch segment is set to
ON
, or as a 1 when that segment is set to
OFF
.
The default configuration for S4 has S4 set to all 0s (all switch
segments set to
ON
). The 162Bug firmware reserves/defines the four
lower order bits (GPI0 to GPI3, switch segments 5-8). Table 2-2
describes the bit assignments on S4.
2. Configure header J1 as appropriate for the desired system controller
functionality (always system controller, never system controller, or
self-regulating) on the MVME162P2.
3. Header J11 enables or disables the IP bus strobe function on the
MVME162P2. The factory configuration puts no jumper on J11,
disabling the Strobe
∗
signal to the Petra/IP2 chip. Verify that this
setting is appropriate for your application.
