Configuring the build

Setup Yocto environment

• WorkDir

mkdir mender-compulab && cd mender-compulab

• CompuLab Yocto build environment
  Follow the instructions of the specific machine and prepare the Yocto Build environemt:

NXP SoC	Build Environment Manual
i.MX8MP	meta-bsp-imx8mp

• Initialize and sync CompuLab Mender repo manifest:

wget --directory-prefix .repo/local_manifests https://raw.githubusercontent.com/compulab-yokneam/meta-mender-compulab/scarthgap-nxp/scripts/mender-compulab.xml
repo sync

• Set environment variables:

NXP SoC	CompuLab Machine	Environment variable
i.MX8MP	iot-gate-imx8plus	export MACHINE=iot-gate-imx8plus
i.MX8MP	iotdin-imx8p	export MACHINE=iotdin-imx8p
i.MX8MP	ucm-imx8m-plus	export MACHINE=ucm-imx8m-plus
i.MX8MP	ucm-imx8m-plus-sbev	export MACHINE=ucm-imx8m-plus-sbev

Setup build environment

• Initialize the build environment:

source mender-setup-environment build-mender-${MACHINE}

• Building the image:

bitbake -k fsl-image-network-full-cmdline

Deployment

Create a bootable media

• Goto the tmp/deploy/images/${MACHINE} directory:

cd tmp/deploy/images/${MACHINE}

• Deploy the image to either sd or usb media:

sudo bmaptool copy --bmap fsl-image-network-full-cmdline-${MACHINE}.sdimg.bmap fsl-image-network-full-cmdline-${MACHINE}.sdimg.bz2 /dev/sdX

Installing the mender image onto the eMMC

• Boot up the device using the created media.
• Wait for the Linux prompt and issue:

cl-deploy

• Wait for 'SUCCESS', then reboot the device.

reboot

• Stop in U-boot, remove the installation media and issue:

env default -a; saveenv; reset
