Edge-2L Build Android
Introduction
This document mainly introduces how to compile the Android source code. You will learn how to compile different versions of Android source code.
Preparation
Building
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 kedge2l-userdebug $ ./build.sh -UCKAou
You can also distribute compilations:
Build U-Boot:
$ cd PATH_YOUR_PROJECT $ source build/envsetup.sh $ lunch kedge2l-userdebug $ ./build.sh -Uu
Build kernel:
$ cd PATH_YOUR_PROJECT $ source build/envsetup.sh $ lunch kedge2l-userdebug $ ./build.sh -CKu
Build Android:
$ cd PATH_YOUR_PROJECT $ source build/envsetup.sh $ lunch kedge2l-userdebug $ ./build.sh -Au
Build OTA:
$ cd PATH_YOUR_PROJECT $ source build/envsetup.sh $ lunch kedge2l-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/ ├── baseparameter.img ├── 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 kedge2l-userdebug $ ./build.sh -u
After compiling, you need to reload update.img when flashing.
