Bringing up the Board
The MVME172P4 comes with MVME172Bug 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
MVME172P4 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 MVME172P4 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 MVME1X2P4 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 172Bug 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 MVME172P4.
3. Header J14 configures the IP bus clock for either 8MHz or the
processor bus clock speed (60MHz for the MC68060 or 64MHz for
the MC68LC060). The factory configuration has a jumper installed
on J14 pins 1-2, denoting an 8MHz clock. Verify that this setting is
appropriate for your application.
