How to use

Simple version

Long version

  • not finished yet

How to build one ?

  • RTFM here : http://s.android.com/source/building.html
  • git clone https://github.com/shakalaca/android_device_asus_a500cg and place the folder in device/asus/a500cg
  • source build/envsetup.sh && lunch aosp_a500cg-userdebug && make -j4
  • for system.img: out/target/product/a500cg/system.img
  • for kernel: out/target/product/a500cg/kernel
  • for ramdisk.img: out/target/product/a500cg/ramdisk.img
  • for creating bootable boot.img: out/host/linux-x86/bin/pack_intel device/asus/a500cg/blobs/boot-ww-2.20.40.13.img kernel ramdisk.img new_boot.img

雖然說是 alpha 版,還是先把目前的成果 release 給有興趣的朋友修改。 :)

檔案放在這:https://github.com/shakalaca/android_device_asus_a500cg

幾點注意事項:

可以先用原廠的 boot.img

  • 單純 AOSP 是沒法編譯出可以動的 boot.img,得透過打包工具將 kernel & ramdisk.img 拼起來。
  • ASUS 對 init 做了不少修改,所以就算拼湊出 boot.img,相機/WiFi/BT.. 都完全沒法用,如果不使用自行編譯的 init 其實整個 ramdisk.img 跟原廠的沒什麼兩樣。
  • 測試過原廠的 boot.img 相對穩定許多。:)

編譯 CM11 開機 audio driver 無法正確載入

  • audio policy 設定出錯,無法設定 output device,推測應該有個 library 得用原廠的。
  • 如果硬要用其實可以刪除 (或跳過) /system/lib/hw/audio*.redhookbay.so,然後在螢幕還沒關起來的狀態下將聲音設定都關閉,可以稍微正常使用。

目前無法使用的功能

  • GPS:gpsd 會 crash
  • ARM program:AOSP 4.4.x 沒有整合 Houdini,不過可以參考 GeeksPhone 的 patch
  • SDCARD:看起來應該是權限或者路徑設定問題,需要 patch。這會造成相機可以 preview 但無法存檔。
  • Video:codec 沒有成功載入。

暫不提供編譯好的 system.img

  • 家裡網路怪怪的,上傳會失敗,請有能力編譯有空間的朋友幫忙產生一版吧。 :)
  • 編譯前請先接上手機執行 extract-files.sh,會從手機上將必要的檔案拉回來編譯 (../../../vendor/asus)

Still in alpha stage, but I think it is better to release early and people interested in AOSP build for ZenFone can jump in :)

Use stock boot.img

  • Of course you can use my tool to pack kernel and ramdisk.img, but BT/WiFi/Camera ... won't work because lots of propietary library only work with init modified by ASUS.
  • Stock boot.img works fine with custom AOSP build .. for now you can just trust it.

Malfunction component

  • GPS: gpsd crashes
  • Program written for ARM platform: Houdini is not integrated in AOSP 4.4.x, but I think we can use the patch from GeeksPhone
  • SD Card: Permission or path configuration issue I thought
  • Video: Not fully tested but most of my test files cannot be played..

For CM11

  • You can build for CM11, but you should remove audio*.redhookbay.so and uncheck all sound releated settings after boot.
  • Need patch from GeeksPhone

For recovery

  • Never have time to build and test :(
