【BeagleBoard】Androidのポーティング【カーネルビルド編】

前回の記事でビルドが完了したのでカーネルのビルドを行います。

今回はbeagleBoard C3用のイメージを作成するので下記のページを参考にdefault configを「omap3_beagle_android_defconfig」にして実行します。

TI-Android-FroYo-DevKit-V2.2 UserGuide - Texas Instruments Wiki

$ cd kernel/
kernel$ make CROSS_COMPILE=../prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- omap3_beagle_android_defconfig
#
# configuration written to .config
#

次に実際のビルドを行います。

カーネルのビルドは特に問題が起きなかったので記事にする必要なかったかも^^;
