Your identity is: imhqq hu.qiqiao@zte.com.cn
If you want to change this, please re-run 'repo init' with --config-name

repo has been initialized in /home/huqiqiao/imx-yocto-bsp

-------------以上已实践-------------
-------------以下待执行-------------
repo sync -f -j8

1、vi ~/bin/repo
修改REPO_URL = https://gerrit-googlesource.lug.ustc.edu.cn/git-repo

2、
git://git.yoctoproject.org 改为 https://git.yoctoproject.org/cgit/cgit.cgi
或者
git config --global url."git://git.yoctoproject.org".insteadOf https://git.yoctoproject.org/cgit/cgit.cgi

编译错误处理:

解决方法：上面文件中，

git://git.yoctoproject.org 改为 https://git.yoctoproject.org/cgit/cgit.cgi
或者
git config --global url."git://git.yoctoproject.org".insteadOf https://git.yoctoproject.org/cgit/cgit.cgi
