init.rc

※上記の広告は60日以上更新のないWIKIに表示されています。更新することで広告が下部へ移動します。

Android 2.2_r1.6 で起動した init.rc です。

デフォルトkernel の proc に無い部分は一応コメントアウトしたが、コメント漏れがあるかも。

ケータイ、データ通信、Wi-Fi 、Bluetooth 周りは試験していない。
また、clean な Android 環境 を目指すべくイロイロな service を起動させていない。

boot.img の ramdisk (root) から dataをdata0にリネーム、system の削除が必要。

適時、自分の環境に読み替える。

init は 2.2r1.3 を makeしたモノを使用。

タッチパネル周りとかがうまくいかなかったら、次のおまじないを…。
service shlcdc_process /system/bin/shlcdc_process
service shdisp_process /system/bin/shdisp_process


追記:2010/12/26 1:22
おまじない不足の様です。もうしばらくお待ち下さい。
追記:2010/12/26 14:42
1.6のsymlink環境に2.2を上書きすれば上記のおまじないでいけます。
個別にコピーしても良いかと…。
詳しく調べていないのはのは大人の事情かな。
追記:2010/12/24 0:07)
先ほど思いついたのですが、mount 以降を data から import できないかと…

  • ありがとうございます。init.rc に追加してみます。 -- (is01rebuild) 2010-12-25 06:43:21
  • タッチパネルのおまじないですが、IS01オリジナル環境から以下のファイルをコピーしてくれば、有効になります。
    Gingerbread 2.3.4_r1 で実際にタッチパネルが使えることを確認しました。
