前提

如果是虚拟机编译，要保证分配至少2核CPU，内存分配16G以上，交换分区至少4G。

0. 解锁bootloader

1. 驱动决定选择源码分支

https://developers.google.com/android/drivers
先找对应的最新驱动：

根据驱动找到分支：
https://source.android.com/docs/setup/about/build-numbers?hl=zh-cn#source-code-tags-and-builds

2. 下载代码

repo init -u https://android.googlesource.com/platform/manifest -b android-12.0.0_r16
repo sync

3. 把驱动放进源码内开始编译

extract-google_devices-flame.sh和extract-qcom-flame.sh，放到AOSP源码根目录,然后执行这两个sh文件，

extract-google_devices-flame.sh

extract-qcom-flame.sh
执行完毕之后会多出几个文件，然后开始编译

source build/envsetup.sh
lunch aosp_flame-userdebug
make -j4

4. 进入out目录进行刷机

fastboot flashall -w

1：找到最新ROM版本

https://developers.google.com/android/images

最新rom

2：根据build ID找到AOSP分支源码

https://github.com/AOSPAlliance/vendor_google_devices/blob/android11/config.json
https://source.android.com/setup/start/build-numbers#source-code-tags-and-builds

build ID

可以看到，RQ3A.210805.001.A1对应的分支是：android-11.0.0_r40

3：下载对应AOSP代码

https://source.android.com/setup/build/downloading

repo init -u https://android.googlesource.com/platform/manifest -b android-11.0.0_r40
repo sync

4：下载驱动，放到AOSP跟目录

https://developers.google.com/android/drivers

5：开始编译代码

https://source.android.com/setup/build/running#selecting-device-build

launch

source build/envsetup.sh
lunch aosp_flame-userdebug
make -j4
