源码下载准备

真机运行需要厂商的驱动，厂商的驱动是不包含在AOSP中的，你需要根据你选择的Branch：
https://source.android.com/source/build-numbers.html
去驱动页面：
https://developers.google.com/android/nexus/drivers#shamulrx21o
下载合适的驱动。

源码下载

下载repo工具:

mkdir ~/bin
PATH=~/bin:$PATH
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo

建立工作目录:

mkdir WORKING_DIRECTORY
cd WORKING_DIRECTORY

把 REPO_URL 一行替换成下面的：

REPO_URL = 'https://gerrit-google.tuna.tsinghua.edu.cn/git-repo'

将repo添加到环境变量, ~/.bashrc文件最后添加下面这行后source ~/.bashrc

export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo/'

初始化仓库:需要某个特定的 Android 版本(以android-6.0.1_r77为例)

repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest -b android-6.0.1_r77

开始同步：

repo sync

刷机

能够adb链接的时候执行 adb reboot bootloader
fastboot devices
如果出现“no permissions fastboot”：

原因：fastboot 没有root权限：
解决：
    到fastboot目录下运行：
        sudo chown root:root fastboot && sudo chmod +s fastboot

fastboot flashall -w

如果出现：“error: neither -p product specified nor ANDROID_PRODUCT_OUT set”
原因：在root模式下没有设置项目的路径。
    解决：
        改变命令为：
            ANDROID_PRODUCT_OUT=out/target/product/hammerhead fastboot flashall -w
