MPV
概要はここ→ https://openit.kek.jp/workshop/2020/dsys/presentation/mpv20201130_baba.pdf
I/O
Firmwareによって異なるが, 一般的に使われているMPVのI/Oは次.
MOCO
1台のMPVにつき, MOCOは6台まで読める. MOCOのIDは下から順番に 0, 1, ..., 5 .
MOCOに接続するVMEモジュールは base address を 0x0000 に設定する必要がある.
MPVCTRL
mpv にログイン後, mpvctrl というコマンドでmocoに接続されたモジュールと通信できる.
ssh root@mpv
単に mpvctrl と叩けば, helpが表示される.
root@mpv22:~# mpvctrl

MAC Address
devtool/findbiid を使う方法
MPVをLANに接続して, 同一LANに存在するマシンで babirl/devtool/findbiid を実行する.
./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

シリアルポート経由でログインする方法
screen /dev/tty.usbserial-AB0M7NK1 115200
mpv22 login: root
Password:
baud rate = 115200 を指定しないと, うまくいかない.
ログインできたら ifconfig でMACアドレスをチェック.
root@mpv22:~# ifconfig
