[玄箱]カーネルの再構築

U-Bootで使える初代玄箱(無印)の2.6.25.20Linuxカーネルを作成する。

まずは、コンパイルに必要なプログラムをインストール。

KURO-BOX:/usr/src# aptitude install patch
KURO-BOX:/usr/src# aptitude install libncurses-dev
KURO-BOX:/usr/src# aptitude install bzip2
KURO-BOX:/usr/src# aptitude install module-init-tools

次に、ソースのダウンロードして、解凍する。

KURO-BOX:/usr/src# wget http://www.genbako.com/kurobox-sources-2.6.25.patch
KURO-BOX:/usr/src# wget http://www.genbako.com/kurobox-section-mismatch2625.patch
KURO-BOX:/usr/src# wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.25.20.tar.bz2
KURO-BOX:/usr/src# tar -jxpvf linux-2.6.25.20.tar.bz2

次に、パッチを当てる。

KURO-BOX:/usr/src# cd linux-2.6.25.20
KURO-BOX:/usr/src/linux-2.6.25.20# patch -Np1 < ../kurobox-section-mismatch2625.patch
KURO-BOX:/usr/src/linux-2.6.25.20# patch -Np1 < ../kurobox-sources-2.6.25.patch

次に、前準備を行う。

KURO-BOX:/usr/src/linux-2.6.25.20# export ARCH=ppc
KURO-BOX:/usr/src/linux-2.6.25.20# cp config_kurobox .config
KURO-BOX:/usr/src/linux-2.6.25.20# make oldconfig

ここで大事なカーネル設定を行う。

KURO-BOX:/usr/src/linux-2.6.25.20# make menuconfig

とりあえず、iptable、IPsec、マルチキャスト、IPIP/GRE トンネル、Dummy インタフェース、ブリッジング、802.1Q VLANとUSB無線LANのいくつかを有効にして設定を保存。
そしてついにコンパイル。ここでuImageを作成します。

無事にuImageが作成できたので続けて、モジュールの作成とインストール

KURO-BOX:/usr/src/linux-2.6.25.20# make modules
KURO-BOX:/usr/src/linux-2.6.25.20# make modules_install

作成しuImageを格納するために既存のものをバックアップする

KURO-BOX:/usr/src/linux-2.6.25.20# cd /boot
KURO-BOX:/boot# ls -la
drwxr-xr-x  3 root    root       4096 2011-06-26 22:35 .
drwxr-xr-x 21 root    root       4096 2011-04-10 05:23 ..

KURO-BOX:/boot# mv System.map System.map.org
KURO-BOX:/boot# mv uImage uImage.org

作成したuImageとコピーする。

KURO-BOX:/boot# cp -p /usr/src/linux-2.6.25.20/arch/ppc/boot/images/uImage /boot
KURO-BOX:/boot# cp -p /usr/src/linux-2.6.25.20/System.map /boot

最終的にはこんな感じ

KURO-BOX:/boot# ls -la
drwxr-xr-x  3 root    root       4096 2011-06-26 22:35 .
drwxr-xr-x 21 root    root       4096 2011-04-10 05:23 ..

lrwxrwxrwx  1 tmp-kun tmp-kun       6 2011-04-10 05:25 vmlinux.UBoot -> uImage
-rwxr-xr-x  1 tmp-kun tmp-kun 3063942 2008-05-04 22:18 vmlinux.bin

これで、再起動後、起動確認。
