MINI2440でのbusybox置き換えのみでpanic ― 2009年08月25日 20時56分32秒
swaponコマンドがリリース版busyboxでは無効
MINI2440の64MBというRAMサイズの場合、swapを有効にしないと決定的にandroid用としてはRAMが足りないというのは各所の情報で明らかでしたので、とりあえず素の状態でswapを有効にしようと思っています。ところが、リリース時点のbusyboxにはswaponがない。単にシンボリックリンクされていないだけではなく、本体のオブジェクト(applet)がリンクされていないようです。
# swapon # swapon: applet not found #
busybox1.13.3をリビルドしてみる
簡単な話だと思いました。提供されているソースコードを元にswaponを有効にした環境でリビルドすればいいのだと。
手順としてはカーネルのビルドと同じようになってるんですね。
- 製品のページにあるソース(busybox-1.13.3-mini2440.tgz)を取得
- make defconfig
- make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- install
# chmod +s busyboxも実行しておきます。
結果は以下のようにpanicで落ちます。

busyboxのサイズの問題？
busyboxのデフォルトの環境でのビルドでpanicしないで起動するかどうかを試した結果が以下。各バージョンのソースはこちらから取得しています。| バージョン | 起動結果 | busyboxサイズ |
|---|---|---|
| 1.13.3 MINI2440同梱版 | OK | 634420 |
| 1.13.3defconfig版 | NG | 798472 |
| 1.13.4defconfig版 | NG | 802160 |

| 1.11.3defconfig版 | OK | 753036 |
| 1.10.4defconfig版 | OK | 744892 |
さて、1.11.3などはpanicでは落ちないものの以下のようにinitの手順が異なるようで、最後まで処理が完了しません。

現在未解決です。試行錯誤中です。解決策を募集します。make menuconfigでかなりオプション指定を削ったつもりでも1.13.3の同梱版ほどコンパクトになりませんし、起動にも失敗しています。
