1.2 创建 yocto 编译环境:
Ubuntu 14.04 编译主机需要事先执行以下命令安装编译所需包：
sudo apt-get update
sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsdl1.2-dev
sudo apt-get install libsdl1.2-dev xterm sed cvs subversion coreutils texi2html docbook-utils python-pysqlite2 help2man
make gcc g++ desktop-file-utils libgl1-mesa-dev libglu1-mesa-dev mercurial autoconf automake groff curl lzop asciidoc
sudo apt-get install u-boot-tools
git config --global user.name xxx
git config --global user.email [email protected]
git config –list
根据文档 imx-yocto-L4.14.98_2.0.0_ga\i.MX_Yocto_Project_User's_Guide.pdf 创建 yocto 编译
环境时，需要注意以下几点：
1.
中国大陆地区无法从 google 的 git 服务器下载 repo 工具，可以改成如下清华的 git 服务器：
mkdir bin
cd bin
curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o repo
chmod a+x repo
export PATH=~/bin:$PATH
2. 可以通过如下地址检查目前可以下载的 manifest：
https://source.codeaurora.org/external/imx/imx-manifest/tree/?h=imx-linux-sumo
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-url=https://mirrors.tuna.tsinghua.edu.cn/git/git-repo
repo sync
3. 建议编译 wayland 后端，而不是编译 fb 后端(对于没有屏的应用如 Tbox，可以使用 fb 后端)。
DISTRO=fsl-imx-wayland MACHINE=imx8qxpmek source fsl-setup-release.sh -b imx8qxpmek_wayland
或者支持 QT 的话编译 xwayland 后端
DISTRO=fsl-imx-xwayland MACHINE=imx8qxpmek source fsl-setup-release.sh -b imx8qxpmek_xwayland
4. 如下命令编译基于 wayland 的支持 GUI 的测试镜像：
bitbake fsl-image-validation-imx -k
或者编译 QT
bitbake fsl-image-qt5-validation-imx -k
5. 编译成功后的输出是：
Wayland：
/imx-yocto-bsp/imx8qxpmek_wayland/tmp/deploy/images/imx8qxpmek/

6. 烧写 SD 卡镜像
Validation image:
bunzip2 -dk -f fsl-image-validation-imx-imx8qxpmek-20190114071748.rootfs.sdcard.bz2
sudo dd if= fsl-image-validation-imx-imx8qxpmek-20190114071748.rootfs.sdcard of=/dev/sd<partition> bs=1M conv=fsync && sync
sync
QT image:
bunzip2 -dk -f fsl-image-qt5-validation-imx-imx8qxpmek-20190731045445.rootfs.sdcard.bz2
sudo dd if= fsl-image-qt5-validation-imx-imx8qxpmek-20190731045445.rootfs.sdcard of=/dev/sd<partition> bs=1M conv=fsync && sync
sync
总共时长：
大约 15 个小时(包括解决问题的时间)。
1.2.1 编译 sdk 及安装
bitbake fsl-image-validation-imx -c populate_sdk 或者：
bitbake fsl-image-qt5-validation-imx -c populate_sdk总共时长大约：2 个小时。
sdk 编译结束后，安装文件地址如下：
~/imx-yocto-bsp/imx8qxpmek_wayland/tmp/deploy/sdk
