KZM-A9-DualボードでLinaro 12.04 ALIPを動かす
KZM-A9-DualでARM Ubuntu 12.04を動かしてみようと思ったのですが、せっかくなのでシンプルなGUIのついたALIP版を動かしてみることにします。
起動可能なSDカードの作成
今回は4GBのSDカードを使いましたが、2GBでも大丈夫そうです。
KZM-A9-Dualのブート可能なSDを作る方法 にしたがって、まずAndroidが起動するSDカードを作成します。
第一パーティションにあるsdboot.binとuboot-sd.binはこのまま使用します。uImageと第3パーティションのユーザーランドはこのあと書き換えます。
ルートファイルシステムのアーカイブの取得
Linaroのダウンロードサイトにあるものを利用しました。
$ mkdir alip $ cd alip/ $ wget http://releases.linaro.org/12.04/ubuntu/precise-images/alip/linaro-precise-alip-20120426-84.tar.gz $ sudo tar pxvf linaro-precise-alip-20120426-84.tar.gz
ルートファイルシステムのSDへの書き込み
SDカードの第3パーティションの内容を置き換えます。
$ cd binary/boot/filesystem.dir/ $ sudo mount /dev/sdb3 /mnt $ sudo rm -rf /mnt/* $ sudo cp -a * /mnt/ $ sudo umount /mnt
uImageの置き換え
Android用のカーネルでは、ANDROID_PARANOID_NETWORK=y になっているので、これを外したカーネルをビルドし、そのuImageをSDカードの第1パーティションに置きます。
make menuconfigでは以下の部分です。

追記
"modprobe: FATAL: Could not load ... " というエラーメッセージはとりあえず以下のように空のファイルを作れば消えます。
root@linaro-alip:~# mkdir -p /lib/modules/`uname -r` root@linaro-alip:~# touch /lib/modules/`uname -r`/modules.dep
"init: Failed to create pty - disabling logging for job" というメッセージはinitの中にあるようです。そのうちソースを見てみます。
root@linaro-alip:~# strings /sbin/init |grep 'create pty' Failed to create pty - disabling logging for job
とりあえずカーネルのコンフィグで、 CONFIG_LEGACY_PTYS=y にしてリビルドしましたが、変りませんでした。
追記(2012.7.4)
init: Failed to create pty - disabling logging for job と出るのは既知のバグのようです。
https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/980917
upstartが起動する前に/dev/pts がmount済みであることを想定しているそうです。通常は
initrdの中でこれを行うらしいのですが、今回のようにそれを省略するとこうなるようです。
