(branch: kirkstone-2.2.0)

Setup Yocto environment:#

mkdir iLCD-bsp && cd iLCD-bsp
export MACHINE=ucm-imx8m-plus

Initialize repo manifests:#

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

mkdir -p .repo/local_manifests

cd sources
git clone -b kirkstone https://demmelproducts@bitbucket.org/imx8mp/meta-demmelproducts.git
cd meta-demmelproducts
cd ..

2. Setup build environment:#

export MACHINE=ucm-imx8m-plus
source compulab-setup-env -b build-${MACHINE}

Add following line to build-ucm-imx8m-plus/conf/bblayers.conf:#

BBLAYERS += "${BSPDIR}/sources/meta-demmelproducts"

Add following line to build-ucm-imx8m-plus/conf/local.conf:#

DRAM_CONF = "d2d4"

3. Build the image:#

You can choose either an image file containing the iLCD demo application, chromium browser, candera and NXP demos by building the demmelproducts-image-demo image

bitbake -k demmelproducts-image-demo

or with debug information included

bitbake -k demmelproducts-image-demo-dbg

or a clean image booting into the weston launcher containing a terminal application only by building the demmelproducts-image-core image.

bitbake -k demmelproducts-image-core

Deployment - create a bootable sd card:#

Go to build-ucm-imx8m-plus/tmp/deploy/images/${MACHINE} directory:#

cd build-ucm-imx8m-plus/tmp/deploy/images/${MACHINE}

Deploy the image:#

zstd -dc <IMAGE NAME>-${MACHINE}.wic.zst > <IMAGE NAME>-${MACHINE}.wic
sudo bmaptool <IMAGE NAME>-${MACHINE}.wic --bmap <IMAGE NAME>-${MACHINE}.wic.bmap /dev/sdX*
