This document mainly introduces how to compile the Android source code. You will learn how to compile different versions of Android source code.
Before you start to build, make sure you have done all the Preperations listed above.
Build ALL:
$ cd PATH_YOUR_PROJECT $ source build/envsetup.sh $ lunch kedge2-userdebug $ ./build.sh -UCKAou
You can also distribute compilations:
Build U-Boot:
$ cd PATH_YOUR_PROJECT $ source build/envsetup.sh $ lunch kedge2-userdebug $ ./build.sh -Uu
Build kernel:
$ cd PATH_YOUR_PROJECT $ source build/envsetup.sh $ lunch kedge2-userdebug $ ./build.sh -CKu
Build Android:
$ cd PATH_YOUR_PROJECT $ source build/envsetup.sh $ lunch kedge2-userdebug $ ./build.sh -Au
Build OTA:
$ cd PATH_YOUR_PROJECT $ source build/envsetup.sh $ lunch kedge2-userdebug $ ./build.sh -ou
Modify the file build.sh BUILD_JOBS=16
as the number you want when you run BUILD_JOBS=n
.
After executing ./build.sh -u
, generate a complete firmware package in the rockdev/Image-xxx/directory
(xxx is the product name of the specific lunch).
rockdev/Image-xxx/ ├── boot-debug.img ├── boot.img ├── config.cfg ├── dtbo.img ├── MiniLoaderAll.bin ├── misc.img ├── parameter.txt ├── pcba_small_misc.img ├── pcba_whole_misc.img ├── recovery.img ├── resource.img ├── super.img ├── uboot.img ├── update.img └── vbmeta.img
Packing update.img:
$ cd PATH_YOUR_PROJECT $ source build/envsetup.sh $ lunch kedge2-userdebug $ ./build.sh -u
After compiling, you need to reload update.img
when flashing.
