組込み徒然草

MINI2440用のカーネルリポジトリのブランチを確認して、それぞれのソースコードからカーネルビルドして試すことにします。

複数のbranchの取得

今回やりたいことはgitリポジトリにあるはずの複数のbranchを試したいということです。

まず、cloneしてリモートのbranchも含めた情報を参照します。

laptop:~/dev/android/mini2440_kernel/mini2440$ git branch
* master
laptop:~/dev/android/mini2440_kernel/mini2440$ git branch -a
* master
  origin/HEAD
  origin/master
  origin/mini2440-dev
  origin/mini2440-dev-extras
  origin/mini2440-dev-likely
  origin/mini2440-dev-unlikely
  origin/mini2440-extras
  origin/mini2440-stable
  origin/mini2440-stable-v2.6.29
  origin/mini2440-stable-v2.6.30
  origin/mini2440-v2.6.31
  origin/origin/HEAD

以上の結果から、以下のbranchを取得することにします。

• mini2440-stable
• mini2440-stable-v2.6.29
• mini2440-stable-v2.6.30

特に、「mini2440-stable」のバージョンが不明ですね。試してみるしかないでしょう。

複数のbranchをcheckoutした様子が以下です。

カーネルビルド

次に「stable」をビルドしてみます。手順ははこれまでと同じです。

laptop:~/dev/android/mini2440_kernel/mini2440$ make ARCH=arm mrproper

上記では「make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- zImage 」は長いので省略。 ビルドが終わった後にuImage.binを以下のように作ります。

laptop:~/dev/android/mini2440_kernel/mini2440/arch/arm/boot$ mkimage -A arm -O linux -T kernel -C none -a 0x30008000 -e 0x30008000 -d zImage uImage.bin

SDカードブート結果

カーネルバージョンは2.6.30.5だったようですが、panicで落ちます。

ついでに標準のviviでのブート結果は以下。
NOR FlashからのブートもNAND Flashからのブートのどちらもカーネル起動でハングアップしてます。なぜ「stable」なのだろうか？

「stable」と同様の手順で「stable-v2.6.29」を試します。
無事起動したので、ベースのバージョンはこれかな。
