I/O
The I/O assignment depends on the firmware, but the commonly used MPV I/O is shown below.
MOCO
One MPV controller can read up to six MOCO boards. MOCO IDs are assigned from bottom to top as 0, 1, ..., 5.
VME modules connected to MOCO must have their base address set to 0x0000.
MPVCTRL
After logging in to mpv, modules connected to MOCO can be controlled with the mpvctrl command.
ssh root@mpv
Running mpvctrl without arguments displays the help message.
root@mpv22:~# mpvctrl

MAC Address
Using devtool/findbiid
Connect the MPV to the LAN, then run babirl/devtool/findbiid on a machine connected to the same LAN.
./findbiid
------------------
BIID = bbdaqsrv
IP = 0.0.0.0
MAC = 00:00:00:00:00:00
Host = onokoro22.gen
------------------
------------------
BIID = bbdaqsrv
IP = 0.0.0.0
MAC = 00:00:00:00:00:00
Host = onokoro00.gen
------------------
------------------
BIID = bbdaqsrv
IP = 172.27.220.180
MAC = 84:47:09:14:48:25
Host = onokoro03.gen

Logging in via the serial port
screen /dev/tty.usbserial-AB0M7NK1 115200
mpv22 login: root
Password:
If baud rate = 115200 is not specified, the connection does not work properly.
After logging in, check the MAC address with ifconfig.
root@mpv22:~# ifconfig
Writing Firmware to MOCO
Firmware can also be written to MOCO from the MPV controller.
Place the firmware mocotrion.hex in /media/sd-mmcblk1p2 on the MPV controller.
First, check whether the flash memory on the MOCO is recognized correctly.
mpvspi -m MOCO -i <moco id (0-5)>
MODULE = MOCO
MOCO 0
res : 0 0xff
res : 1 0xef
res : 2 0x40
res : 3 0x16
res : 4 0x00
res : 5 0x00
If res1 to res3 are as follows, the MOCO is recognized correctly.
res : 1 0xef
res : 2 0x40
res : 3 0x16
The firmware can be written with the following commands.
cd /media/sd-mmcblk1p2/
mpvspi -m MOCO -e -w <moco id (0-5)> mocotrion.hex
Writing takes about one minute. When writing is complete, the LED on the MOCO turns on.
After writing, test with mpvctrl to check whether the firmware was written correctly.
root@mpv22:/media/sd-mmcblk1p2# mpvctrl enable moco0 mocol moco2 moco3 moco4 moco5

Sometimes firmware cannot be written to the MOCO inserted in the MOCO0 position. In that case, move it to another slot and try writing again.
