玄箱PRO でも Windowsマシンで使っている NTFS フォーマットのUSB外付けハードディスクを使ってみたくなりました。最近では Linux でも ntfs-3g を使うとNTFSの読み書きが問題なくできるようになっています。玄箱PRO で ntfs-3g を使うためにはカーネルにFUSEドライバを組み込む必要があります。ちょうど 2008/07/13 に 2.6．25.11 が公開されたので、標準のカーネルを玄箱PROで使うテストを兼ねて、FUSEドライバを組み込むためカーネルを gcc-4.1 でセルフコンパイルしてみました。
カーネルのコンパイルは基本的に https://buffalo.nas-central.org/index.php/Buffalo_ARM9_Kernel_Portの手順に従いました。
パッチを適用しない plain vanilla な linux-2.6.25.11 でも、玄箱PRO で動作するようになっていますが、まだ電源ボタンの長押しで電源OFFができないようです。電源OFFのためにログインして「shutdown -hP now」を実行しなくてはならないのでは困るため、 Sylver Bruneau 氏のパッチを修正して適用して、また Keventd を修正することで電源ボタンの長押しで電源OFF出来るようにしました。
2008/08/09 linux-2.6.26.2 に関して追記。
カーネルのコンパイルには devio と mkimage が必要です。インストールされていない場合は以下のように apt-get してください。
apt-get install uboot-mkimage apt-get install devio
Debian lenny では gcc-4.1 も必要です。
apt-get install gcc-4.1
カーネルのコンパイルには必要ありませんが、ntfs-3g を使用する場合はインストールします。(etch にはないかもしれません)
apt-get install ntfs-3g
kernel.org から plain vanillaなカーネルソースを入手します。私は /usr/src に linux-2.6.25.11.tar.bz2 を置いて作業しました。

real 4m50.576s
user 3m45.990s

/usr/src/linux を /usr/src/linux-2.6.25.11/ へのシンボリックリンクとして作成して作業しました。
KUROBOX-PRO:/usr/src# ln -s linux-2.6.25.11 linux
シャットダウン時に電源を切れるように Sylver Bruneau 氏のパッチ( https://marc.info/?l=linux-arm-kernel&m=120963179224741&w=2) を適用しますが、2.6.26用のため 2.5.25.11用に変更します。基本的に orion5x_ から orion_ への変更だけです。(パッチ)

起動時にUSBドライブが接続されている場合、手動でマウントしなくても使えるように以下のように設定しました。もっとスマートな方法があるはずですが、まずは動作確認です。
/dev/sdb は noauto として起動時にマウントしていません。
# UNCONFIGURED FSTAB FOR BASE SYSTEM proc /proc proc defaults 0 0 sysfs /sys sysfs defaults 0 0 devpts /dev/pts devpts gid=4,mode=620 0 0 /dev/sda2 / ext3 defaults 1 0 /dev/sda4 /home ext3 defaults 1 0 /dev/sda3 swap swap defaults 0 0 /dev/sdb1 /mnt/sdb1 ntfs-3g noauto,rw,exec,uid=1000,locale=ja_JP.UTF-8 0 0 /dev/sdb2 /mnt/sdb2 ntfs-3g noauto,rw,exec,uid=1000,locale=ja_JP.UTF-8 0 0 /dev/sdb3 /mnt/sdb3 ntfs-3g noauto,rw,exec,uid=1000,locale=ja_JP.UTF-8 0 0 /dev/sdb5 /mnt/sdb5 ntfs-3g noauto,rw,exec,uid=1000,locale=ja_JP.UTF-8 0 0
rc.local で起動の最終段階でマウントしています。USBドライブが接続されていない場合はコンソールにエラー表示されますが、実害はありません。

玄箱PROでNTFSを使えるまでの失敗も記録しておきます。Debian lenny の環境で2.6.25.11、2.6.26ともにセルフコンパイルしましたが、カーネルが正常に起動しませんでした。どちらもコンソールに以下のように表示したまま停止します。

すると 2.6.25.11 では以下のようなエラーの結果、カーネルパニックになっていました。

どうもコンパイラが怪しそうです。lenny の gcc のバージョンは 4.3.1 ですが、gcc-4.1 で試すと 2.6.25.11 では正常に起動しました。
2.6.26 では gcc-4.1 でも、以下のように表示してエラーもなく停止します。

掲示板で吉山さんに教えて頂いた部分を修正して、linux-2.6.26.2 をコンパイルしてみたところ2.6.26.2でも正常に動作しました。
上記の2.6.25.11で行った作業のうち、シャットダウン時に電源を切れるようにする Sylver Bruneau 氏のパッチ( https://marc.info/?l=linux-arm-kernel&m=120963179224741&w=2)はそのまま適用します。また、教えて頂いたhttps://marc.info/?l=linux-arm-kernel&m=121774486709422&w=2)は以下のようにソースを直接変更しました。

今回もコンパイラは gcc-4.1 を使いました。95分でコンパイル終了。
