Intro:

Setup:

starting the real time clock on a new board (with mvme proms)
initializing the nvram parameters in the vxWorks eprom

SETUP:

Starting the real time clock (pg 3-25 of installation guide)

This is done with the mvme bug proms still in..(my bbram routines may also do it?).
allow bug to boot up,
select 3 to got do mv167 bug
time .. will display the time
Use SET command to initialize the clock:

set mmddyyhhmm .. so you probably want to hit enter on a 1 minute ..

Initializing the nvram data for a new eprom

install a vw eprom in the sbc.
connect rs232 cable from laptop to serial port on board:

167 board. serial port 1/console on the mv712expansion board on the back of vme crate
162 board. serial port 1/console front panel of the 162 board
laptop:

use usb to rs232 adapter

cables:

in phil's office to the left of the phone, hanging on the window opener. Includes cables, usb to rs232 and null modem

modem program.

i use minicom. 8 bits 1stop bit, no parity, no hardware handshake.
you may need to chmod on /dev/ttyUSB to allow access to non root users.

with cables plugged in, and modem program running, reset the sbc.

if nothing appears on screen.. insert the null modem. I think the 162's want the null modem, the 167 doesn't (or maybe that's reversed..)

when output appears on screen.. hit a character to stop the boot sequence.
p will print the current config (if a new eprom.. it may be garbage)
c lets you change the fields

you need to go through fields 1 by 1
An example da is : c

boot device          : ei
processor number     : 0
host name            : observerT
file name            : /home/online/vw/boot/mv167/vxWorks
inet on ethernet (e) : 192.160.174.2:ffffff00
inet on backplane (b): 192.160.176.1
host inet (h)        : 192.160.174.10
user (u)             : vxw
flags (f)            : 0x0
target name (tn)     : da
startup script (s)   : /home/online/vw/boot/da/mv167/startup.p0
Some of the fields may not be requested..

On the backplane, the cpus only have inet on backplane

The init values to use for each cpu

When done boot the sbc

I think it is @ . (but just do h for help and it will print the commands).

Special edits for the da computer.

An interrupt is used to synchronize the sbc to the harware 1 second tick. This is done once a second.
Most sbc use a printer interrupt to bring in the hardware 1 second tick
The initial da sbc was a mv167-34a. This board does not have a printer interrupt.

We used a gpio pin as the interrupt source for this board (there is a cable that plugs into the front of the board.

If you switch between a mv167-34A (front panel interrupt) and a mv167-04a (printer interrupt):

you need to tell the extTickInit() routine where the interrupt comes from (gpio..front panel, d (back panel).
edit the file: /home/online/vw/boot/da/mv167/startup.p0 (this is the starup file for da)
around line 243..
for rear panel interrupt (mv167-04a)

# pjp 27nov16 commented out gpio, replaced with "d" to use cor cpu as da
#extTickInit("gpio")
extTickInit("d")

for front panel tick interrupt (mv167-034a)

# pjp 27nov16 commented out gpio, replaced with "d" to use cor cpu as da
extTickInit("gpio")
#extTickInit("d")

List of AO boards

The table below is a partial list of the motorola boards we are using for datataking (using vxWorks) at ao. The table also includes spares and boards that have died
If assigned a number (AO# n) to each board. There should be a sticker on the front of each board with this number (for identification).
Status codes:

D dead, no longer in used
T board has trouble. not completely dead
OK .. ok

Board Types:

mv167-04a 25 MHz, 32 MB
mv167-02b 25 Mhz, 8MB
mv167-034a 33 Mhz, 32 MB (needs gpio ..front panel..for 1 second tick interrupt .. on printer interrupt)
mv167-034b 33 MHz 32MB (uses printer interrupt for 1 second tick .. from the back)
mv162xxxy

4xx 68Lc040 (no fp?)
5xx 68040
x10 -4mb
x20 - 8mb
x30 - 16mb
xx1 - scsi included
xx2 - ethernet included
y - major revision level

mv162-513 32MHz, 4 MB (earlier version of mv162fx boards..though mvme bug calls the 513a boards.
mv162-513a 32Mhz, 4 MB
mv162-533a 32MHz, 16MB?

AO #	mvme #	serial #	status	notes,
1	mv167-04a	1199939	D	10sep14: purchased after pntCrate failure 11sep14: installed in rfi rack slot1 when mv147 cpu failed did not run reliably..removed cpu and sent back to company
