MINI2440へのandroidポーティングへの道 ― 2009年08月20日 15時53分58秒
今いじっているMINI2440はandroidポーティングを目指していますが、そんなに簡単なことじゃないということを整理して、作業項目を洗い出しましょう。
そもそもAndroidと標準のLinuxの違い
ソースとってきて差分とってパッチ当ててビルドしたら終わり、なんて簡単なことじゃないです。 きちんと意味を理解しておかないとそれぞれの修正もできない。
そもそも標準のLinuxとの違いが整理された資料を見つけられない。googleのどっかにおいてあるとは思うのですが、まだそこまで見つけられていません。
CE Linux ForumのTOMOYO Linuxのセミナー資料がちょっと分かりやすい。
上記資料の抜粋を含めて整理すると以下のようなことか。
- 標準のLinuxのユーティリティの削減(toolbox)
- glibcは使えない(Bionicを使う)
- IPCが標準と違う(Binder)
- ネイティブなwindowシステムがない
- パワーマネージメントシステムを最適化
- Low memory killer, Alarm, Kernel Debugger, etc.
- zygoteとDalvikVM
- SDK用の標準エミュレータ用にgoldfishという仮想のARMマシンとして構築されている
- H/Wに依存するデバイスドライバの類とかDalvikVMの接続のあたりが不明
ポーティングプラン
- MINI2440のNAND FLASHにカーネルイメージを置くにはサイズが足りないので、とにかく外部デバイスでブートできるようにならなければならない
- MINI2440はARMなので基本的にはgoldfishのバイナリが使えるはず
- なので、toolboxはgoldfishのものがそのまま使えるはず
- Bionicはgoldfishのものがそのまま使えるはず
- カーネルはandroidのものをベースに考えるか標準のMINI2440のものをベースに考えるかで作業が異なる
- いろいろと標準のコンソールを使いたいので標準環境MINI2440に拡張していく形を検討
- 仮想バッテリドライバの開発?構築?でMINI2440対応
- 各種デバイスドライバの対応
なお、JTAG ICEは必要になってくると思うのでそちらの環境整備も検討。
外部デバイスからのブート
実はこいつではまってます。 全く標準のカーネルイメージをmkimageでu-boot用のイメージに変換して、SDメモリカードのFATにコピーしてブートを試みるも、起動しない。 このカーネルはもちろんNAND Flashからは起動するもの。
外部デバイスからのブートについては以下の方法があります。
- SDメモリカードのFAT領域からのブート(u-boot1.3.x以降?必要)
- USBメモリからのブート(u-boot1.3.x以降?必要)
- TFTPまたはNFSルートからのブート(viviで対応可能)
カーネルそのものには問題ないと考えてu-bootの方を試行錯誤している最中。
今後の予定
ということで、android云々前にブートについて整理と試行錯誤が必要で、これにけりがついたらandroidのソースをいじり始めることになると思います。その前にブート手順の中身の理解やファイル構成などの把握も必要。
SDメモリーカードからのブートが無理そうならUSBブートを試して最終的にはNFS対応で当面逃げる。でも、最終的には戻ってこないといけませんね。
・・・と思ったらMINI2440用の最新カーネル2.6.31をビルドしてSDメモリーカードに書いたらあっさり起動しましたね。これについては別途書きますが、何でカーネルに依存して起動しなかったのかの理屈がわかりませんね。
ルートファイルシステムの中身は2.6.29の時のオリジナルのまま展開したものでOKでした。
MINI2440でのSDカードブート ― 2009年08月20日 17時17分53秒
u-boot1.3.2でのSDカードブートが出来ない問題とは本質的には関係ないと思いつつ、新しいカーネルソースを取得してビルド、SDカード書き込みでブートできましたので、おさらいも含めて書いておきます。
SDカードの諸元
- MicroSD2GB使用
- カードアダプタでMINI2440に装着
- ubuntu Linux9.0.4環境でFdisk
- パーティションはFAT,Linux,swapの三つ
- swapパーティションは使える状況になった時にすぐに対応出来るように予め確保
- 2番めのlinuxパーティションはext3でフォーマット
USBリーダ経由でMicroSDカードをfdiskで参照したパーティションの状況です。

u-bootのビルド
もともと預った時点のNAND Flashの状態のu-bootを使用していますが、http://wiki.linuxmce.org/index.php/Mini2440にある手順のとおりにソース取得、ビルド可能です。
クロス環境は一貫しておいた方が良いので、カーネルビルドも含めて正式サイトで紹介されているarm-linux-gcc-4.3.2.tgzをそのまま使っています。 以下はubootソースコードの取得状況です。
$ git clone git://repo.or.cz/u-boot-openmoko/mini2440.git Initialized empty Git repository in /media/mini2440/uboot/mini2440/.git/ remote: Counting objects: 57585, done. remote: Compressing objects: 100% (11111/11111), done. remote: Total 57585 (delta 46282), reused 57433 (delta 46146) Receiving objects: 100% (57585/57585), 24.42 MiB | 208 KiB/s, done. Resolving deltas: 100% (46282/46282 done. Checking out files: 100% (5232/5232), done. $
続いて、コンパイル。
- export CROSS_COMPILE=arm-none-linux-gnueabi-
- cd mini2440
- make mini2440_config
- make all
出来上がったubootのイメージ(u-boot.bin)のNAND領域への書き込みはsuperviviで[a]を選択して、DNWよりダウンロードする方法で可能です。 ただし、この方法での書き込みではsaveenvで設定値の保存ができませんでしたのできちんとNAND Flashの構成を考えて設定し直しが必要だと思います。 とりあえず私はバックアップしてあったイメージをNAND Flashに書き込んだ上で、カーネルとルートファイルシステムを上書きした状態にして作業を行っています。
u-bootの設定
おさらいで、u-bootの設定も確認しておきます。

SDブートできない状況
オリジナルの2.6.29カーネルをext3対応に拡張してビルドして、mkimageで変換したものをSDカードに書いたものでブートした状況は以下です。
U-Boot 1.3.2-mini2440 (Jul 8 2009 - 13:25:23) I2C: ready DRAM: 64 MB Flash: 2 MB NAND: 64 MiB Found Environment offset in OOB..

上記のようにハングアップしてしまいます。
SDブート出来るようになった手順
u-bootも含めてNAND Flashの状態を変えないでSDカードに書くuImage.binのみ以下の手順で入れ替えます。
http://www.friendlyarm.org/topic.asp?TOPIC_ID=42の情報によりカーネルソースを取得してビルドします。
- git clone git://repo.or.cz/linux-2.6/mini2440.git
- cd mini2440
- make ARCH=arm mrproper
- make ARCH=arm mini2440_defconfig
- make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- zImage
- cd arch
- cd arm
- cd boot
- mkimage -A arm -O linux -T kernel -C none -a 0x30008000 -e 0x30008000 -d zImage uImage.bin
これで出来上がったuImage.binをSDカードのFAT領域にコピーします。 カーネルのバージョンは2.6.31にあがっていました。 ブート結果は以下。

既に述べたように、NAND FlashにはU-boot,2.6.29kernel,2.6.29rootfsが書き込んであります。 この状態でU-bootの設定はSDメモリーカードからの起動に設定してあるのですが、NOR Flashから起動して[b]を入力すると、NANDに書き込んであるカーネルとファイルシステムで起動します。
