Quick Start part:
Install the `repo` utility:
To get the BSP you need to have "repo" installed. This only needs to be done once.
$: mkdir ~/bin
$: curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$: chmod a+x ~/bin/repo
$: PATH=${PATH}:~/bin
由於這里安裝repo的REPO_URL是谷歌的源，而由於國內“牆”的原因導致下載失敗，錯誤為
fatal: Cannot get https://gerrit.googlesource.com/git-repo/clone.bundle
fatal: error [Errno 101] Network is unreachable
針對這個問題，解決方案如下：
1. 獲取repo
# cd ~
# mkdir bin
# cd bin
# curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo > ~/bin/repo
# chmod a+x ~/bin/repo
# export PATH=${PATH}:~/bin
2. 修改repo文件
打開~/bin/repo文件並修改google地址
# vi ~/bin/repo
From
REPO_URL = 'https://gerrit.googlesource.com/git-repo'
To
REPO_URL = 'https://mirrors.tuna.tsinghua.edu.cn/git/git-repo/'
