前提
如果是虛擬機(jī)編譯，要保證分配至少2核CPU，內(nèi)存分配16G以上，交換分區(qū)至少4G。

0. 解鎖bootloader
https://source.android.com/setup/build/running#unlocking-the-bootloader
1. 驅(qū)動決定選擇源碼分支
https://developers.google.com/android/drivers
先找對應(yīng)的最新驅(qū)動：
根據(jù)驅(qū)動找到分支：
https://source.android.com/docs/setup/about/build-numbers?hl=zh-cn#source-code-tags-and-builds
2. 下載代碼
repo init -u https://android.googlesource.com/platform/manifest -b android-12.0.0_r16
repo sync
3. 把驅(qū)動放進(jìn)源碼內(nèi)開始編譯
extract-google_devices-flame.sh和extract-qcom-flame.sh，放到AOSP源碼根目錄,然后執(zhí)行這兩個sh文件，
extract-google_devices-flame.sh
extract-qcom-flame.sh
執(zhí)行完畢之后會多出幾個文件，然后開始編譯
source build/envsetup.sh
lunch aosp_flame-userdebug
make -j4
4. 進(jìn)入out目錄進(jìn)行刷機(jī)
fastboot flashall -w
1：找到最新ROM版本
https://developers.google.com/android/images
最新版本如下：
11.0.0 (RQ3A.210805.001.A1, Aug 2021)格式如下：
Android版本號（build ID，時間）
2：根據(jù)build ID找到AOSP分支源碼
https://github.com/AOSPAlliance/vendor_google_devices/blob/android11/config.json
https://source.android.com/setup/start/build-numbers#source-code-tags-and-builds
可以看到，RQ3A.210805.001.A1對應(yīng)的分支是：android-11.0.0_r40
3：下載對應(yīng)AOSP代碼
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：下載驅(qū)動，放到AOSP跟目錄
https://developers.google.com/android/drivers
5：開始編譯代碼
https://source.android.com/setup/build/running#selecting-device-build
source build/envsetup.sh
lunch aosp_flame-userdebug
make -j4
