SDK编译环境需要ubuntu系统，先安装ubuntu20.04系统,再安装如下必须的包

sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib uild-essential chrpath socat cpio python python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev pylint3 xterm rsync curl

curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o ~/bin/repo #下载repo工具
chmod a+x ~/bin/repo
vi ~/bin/repo
修改如下 REPO_URL = "https://mirrors.tuna.tsinghua.edu.cn/git/git-repo"
repo init -u https://github.com/nxp-qoriq/yocto-sdk -b mickledore -m ls-6.1.22-2.0.0_distro.xml
DISTRO=fsl-qoriq-distro MACHINE=ls1043ardb source distro-setup-env
bitbake ls-image-main
bitbake ls-image-main --runall=fetch  #执行此命令可以先下载软件包，下载完后再编译会加快编译时间
bitbake qoriq-composite-firmware #生成firmware
bitbake generate-boottgz #生成boot包
cp meta-nxp-desktop/scripts/flex-installer_1.14.2110.lf /usr/bin/flexinstaller
sudo chmod a+x /usr/bin/flex-installer   #安装flex-installer工具
flex-installer -f firmware_ls1043ardb_uboot_sdboot.img -b boot_ls1043ardb_lts_6.1.tgz -r ls-image-main-ls1043ardb-20231104084043.rootfs.tar.gz -d /dev/sdbx    #此命令安装三个包到sd卡设备 一般设备名是/dev/sdx，x代表实际名称
