首先是主要的 Yocto 项目poky层
git clone -b dunfell git://git.yoctoproject.org/poky.git poky-dunfell

依赖层
cd poky-dunfell
git clone -b dunfell git://git.openembedded.org/meta-openembedded
git clone -b dunfell https://github.com/meta-qt5/meta-qt5
git clone -b dunfell git://git.yoctoproject.org/meta-raspberrypi
git clone -b dunfell git://git.yoctoproject.org/meta-security.git


通用层
git clone -b dunfell https://github.com/jumpnow/meta-jumpnow

rpi 存储库
git clone -b dunfell git://github.com/jumpnow/meta-rpi64

mkdir ~/rpi64-taotaodiy
cd ~/rpi64-taotaodiy



mkdir -p ~/rpi64/build/conf
source poky-dunfell/oe-init-build-env ~/rpi64/build

自定义配置文件
meta-rpi/conf目录中有一些示例配置文件，将它们复制到build/conf目录（删除“-sample”）

cp meta-rpi64/conf/local.conf.sample build/conf/local.conf
cp meta-rpi64/conf/bblayers.conf.sample build/conf/bblayers.conf


source poky-dunfell/oe-init-build-env poky-dunfell/rpi64-taotaodiy/build/
source oe-init-build-env rpi64/build/
