- Download CompuLab BSP
git clone -b ${CPL_BRANCH} https://github.com/compulab-yokneam/meta-bsp-imx8mm.git
export PATCHES=$(pwd)/meta-bsp-imx8mm/recipes-kernel/linux/compulab/imx8mm
CompuLab Linux Kernel setup
git clone -b ${NXP_BRANCH} --single-branch https://github.com/nxp-imx/linux-imx.git
git -C linux-imx checkout ${NXP_RELEASE} -b linux-compulab
git -C linux-imx am ${PATCHES}/*.patch
