Panda ICSビルド

android ICS

solaさんの追試。
ローカルのAOSPミラーを使う。

kinneko@BuildSV:~/panda$ mkdir ics
kinneko@BuildSV:~/panda$ cd ics/
kinneko@BuildSV:~/panda/ics$ ../../repo init -u /home/kinneko/AOSP/platform/manifest.git 
kinneko@BuildSV:~/panda/ics$ ../../repo sync

SGXドライバなどを追加。

kinneko@BuildSV:~/panda/ics$ wget https://dl.google.com/dl/android/aosp/imgtec-panda-itl41d-dfebf249.tgz
kinneko@BuildSV:~/panda/ics$ tar zxf imgtec-panda-itl41d-dfebf249.tgz
kinneko@BuildSV:~/panda/ics$ ./extract-imgtec-panda.sh

ここの操作は、１つ前と同じ。


ビルド。

kinneko@BuildSV:~/panda/ics$ rm imgtec-panda-itl41d-dfebf249.tgz extract-imgtec-panda.sh 
kinneko@BuildSV:~/panda/ics$ source build/envsetup.sh
including device/samsung/maguro/vendorsetup.sh

rootfsのツリーを作る。

kinneko@BuildSV:~/panda/ics/kernel$ cd ../out/target/product/panda/
kinneko@BuildSV:~/panda/ics/out/target/product/panda$ cp -a root/* rootfs/
kinneko@BuildSV:~/panda/ics/out/target/product/panda$ cp -a system rootfs/
kinneko@BuildSV:~/panda/ics/out/target/product/panda$ vi rootfs/init.rc

以下をコメントアウト。

on fs
# mount mtd partitions
    # Mount /system rw first to give the filesystem a chance to save a checkpoint

以下変更。

できたファイルをSDCardにコピーする。
カードリーダーに2GBのSDCard挿す。
認識されたデバイス名を探す。

kinneko@BuildSV:~/panda$ dmesg

sdbのようだ。
メディアのパーティション情報を削除。
全部消えるので注意。

kinneko@BuildSV:~/panda$ sudo dd if=/dev/zero of=/dev/sdb bs=1 count=1024

３つパーティションを作成。
起動用のbootと、Android動いた時にsdcardとして認識されるmediaと、Androidのシステムが入るrootfs。

出来上がり。
でも、テストするpandaが手元にない(^^;。


んー、実機では、kernelまで上がるけど、rootfsが来ない。
シェルに落ちて操作はできるな。


どこがマズいかな...


ディスプレイ変更したら普通に出た。

[    4.125762] Waiting 2sec before mounting root device...

のとこで、５秒くらい待っている感じがするけど。
HDMIなのに出力を選ぶのか？
あ、DVI側につないでたんだった(^^;。それは選ぶかも。
スクエアなモニタなので、表示が歪んでいる。
