1、初始化Yocto环境的设置脚本
$ ./b2qt-init-build-env init --device raspberrypi3

生成下面的脚本文件和文件夹：

setup-environment.sh 、 sources 、 build-raspberrypi3


export MACHINE=raspberrypi3
source ./setup-environment.sh

bitbake b2qt-embedded-qt6-image
bitbake meta-toolchain-b2qt-embedded-qt6-sdk



source nxp-setup-alb.sh -m s32g274ardb2 -d ../downloads
source nxp-setup-alb.sh -m s32g274ardb2ubuntu -d ../downloads -c ./sstate-cache -b ./build_s32g274ardb2
source nxp-setup-alb.sh -m s32g274ardb2ubuntu -d ../downloads -c ./sstate-cache -b ./build_s32g274ardb2 -e "meta-aws meta-java" -D fsl-goldvip

## Rebuild U-Boot
bitbake -c compile -f u-boot
## Deploy U-Boot
bitbake u-boot

bitbake -c compile -f virtual/bootloader
