Configuring the build

Setup Yocto environment

• WorkDir:

mkdir compulab-nxp-bsp && cd compulab-nxp-bsp

• Set a CompuLab machine:

export MACHINE=ucm-imx93

Initialize repo manifests

• NXP

repo init -u https://github.com/nxp-imx/imx-manifest.git -b imx-linux-kirkstone -m imx-5.15.71-2.2.0.xml

• CompuLab

mkdir -p .repo/local_manifests
wget --directory-prefix .repo/local_manifests https://raw.githubusercontent.com/compulab-yokneam/meta-bsp-imx9/kirkstone-2.2.0/scripts/meta-bsp-imx9.xml

• Sync Them all

repo sync

Setup build environment

• Initialize the build environment:

source compulab-setup-env -b build-${MACHINE}

Building full rootfs image:

• Build command

bitbake -k imx-image-full

• binary file location : ${BUILDDIR}/tmp/deploy/images/${MACHINE}/imx-image-full-${MACHINE}.wic.bz2

Deployment

Create a live SD card

cd ${BUILDDIR}/tmp/deploy/images/${MACHINE}

• Deploy the image:

sudo zstd -dc imx-image-full-${MACHINE}-*.rootfs.wic.zst | sudo dd bs=1M status=progress of=/dev/sdX

Optional targets

• Building bootloader only:

• Build command

bitbake -k imx-boot

• binary file location : ${BUILDDIR}/tmp/deploy/images/${MACHINE}/imx-boot-tagged
