关于Yocto环境构建流程笔记

To install the “repo” utility, perform these steps:

1. Create a bin folder in the home directory.
   Host Setup
   i.MX Yocto Project User’s Guide, Rev. L4.14.98-2.0.0_ga, 04/2019
   NXP Semiconductors 5

$ mkdir ~/bin (this step may not be needed if the bin folder already exists)
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
2. Add the following line to the  .bashrc file to ensure that the  ~/bin folder is in your PATH variable.
export PATH=~/bin:$PATH

First make sure that git is set up properly with the commands below.

$ git config --global user.name "sunxiaolin2016"
$ git config --global user.email "[email protected]"
$ git config --list

$ mkdir imx-yocto-bsp
$ cd imx-yocto-bsp
$ repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-sumo -m imx-4.14.98-2.0.0_ga.xml
$ repo sync

问题：https://gerrit.googlesource.com/git-repo/clone.bundle无法访问，repo无法正常进行。
报错：

Cannot get http://gerrit.googlesource.com/git-repo/clone.bundle

解决：
参考资料https://mirrors.tuna.tsinghua.edu.cn/help/git-repo/
重做下载：

curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o repo 
chmod +x repo

重做更新：

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

重启终端terminal生效。

5.编译配置
DISTRO=fsl-imx-xwayland MACHINE=imx8qmmek source fsl-setup-release.sh -b build-x11
DISTRO=fsl-imx-xwayland MACHINE=imx8qmmek source fsl-setup-release.sh -b build-xwayland

6.编译，选择yocto image

bitbake fsl-image-validation-imx
bitbake fsl-image-qt5-validation-imx
