- CF 積んで
- ETHER-0 に UTP ケーブル接続して
- INIT ボタンをボールペンで押さえて
- パーティション分割 & ファイルシステム作成 8G を 6G / 2G に分割。冗長だけど全部
- マウント & ファイル取得準備
- 開発機側のファイルツリーをごっそり取得
- チルっと
- /uImage.initrd-cfboot の作成
$SSDSRC/usr/src/contrib/debootstrap/post-debootstrap $SSDSRC/usr/src/contrib/developers/kimura/lenny_based_firmware/uimage/create_uImage.sh - 普通の? 必須修正
- オリジナルツールのコピー 後でやっつけパッケージ作るけど、とり急ぎ
- CF ブートとしてリブート
