USL-5Pで遊ぶ

iodata の USL-5P を Linux マシンとして遊ぶ。
USL-5P は基本的には LANDISK から PCI-IDE を取り外して、 CFから起動できるようになって、小さくなったと思えばよい。

シリアルコンソールをつける

バッテリのそばのJP1にシリアル信号が出ている。 ピンの配置はLANDISKと同じ。 3.3V対応の232Cバストランシーバ回路をつければOK。

カーネルの入れ替え

LANDISKのソースを使ってUSL-5Pで起動するカーネルをビルドする。
LANDISKのソースにはCFアクセス用のコードが既に用意されたので、ためしにビルドしたら動いた。

以下はNFSroot用の .config。

nfsroot での起動

いろいろと実験するのに毎回CFを入れ替えるのが面倒なので、NFSrootできるようにする。 ポイントは次のとおり。

liloの設定例

ビルドしたカーネルをコピーして、lilo を実行する。 

linear
boot=/dev/sda  (母艦でのデバイス)
disk=/dev/sda
bios=0x80
timeout=50
default=nfsroot
install=/boot/boot-sel.b-v214
image=/boot/zImage.new
        label=nfsroot
        root=/dev/hda1
        read-only
        append="mem=64M root=/dev/nfs rw console=ttySC1,9600 ip=::::::bootp"
(rw をつけること)

rootfsの用意

iohack のdebianベースを使わせていただく。

  1. baseを展開 
    # mkdir $ROOTFSDIR
# cd $ROOTFSDIR
# tar xvfj base-sh4-for-landisk-20041122.tar.bz2
  2. etc/fstabを編集 
    /dev/nfs        /       nfs     defaults,errors=remount-ro 0 0
  3. etc/network/interfaces 
    auto lo
iface lo inet loopback
  4. etc/inittabを編集
  5. etc/securettyを編集
  6. etc/hosts, etc/resolv.confを適切に編集
詳細省略部分はdebianのセットアップの例 を参考にする。

BOOTPサーバの設定

dhcp-2.0pl5-6vl1 の例 

/etc/dhcpd.conf
---
subnet 192.168.0.0 netmask 255.255.255.0 {

  host usl5p {
        hardware ethernet 00:a0:b0:65:xx:xx;
        fixed-address 192.168.0.xxx;   (USL-5Pに与えるアドレス)
        option routers 192.168.0.1;    (defaultroute)
        option host-name "usl5p";

        option root-path "$NFSROOT";   (NFS export された rootfs TOP)
  }

}

NFSサーバの設定

/etc/exports

$NFSROOT 192.168.0.xxx/255.255.255.255(rw,no_root_squash)

あとはお好きに

iohack のベースは既に apt の設定が済んでいるので、 apt-get で足りないパッケージを探してインストールするだけ。
