“-bash: /home/grayli/test_case/yocto/imx-yocto-bsp/sources/poky/oe-init-build-env: No such file or directory” this is error message when you use the command "DISTRO=fsl-imx-xwayland MACHINE=imx8qxpc0mek source imx-setup-release.sh -b build"??
did you install all of package the ubuntu needs? what ubuntu version do you use? don't forget to build packages, can refer to the chapter 3 Host Setup and chapter 3.1 Host packages of yocto user guide
