Introduction

Meta-somlabs-desktop is a layer providing the SoMLabs modules and carrier boards hardware support for NXP Ubuntu PoC system. It has to be used on top of the meta-nxp-desktop:

System image

This layer should be used in order to build the Ubuntu PoC system image. It adds support for the SoMLabs modules based on iMX8Mmini and iMX8MPlus processors.

Building the system image

The general description of the building process is described in the meta-nxp-desktop repository README.md file for mickledore 6.1.36-2.1.0- version:

https://github.com/nxp-imx/meta-nxp-desktop/blob/lf-6.1.36-2.1.0-mickledore/README.md

The summary of required steps including the meta-somlabs layer is shown below.

mkdir imx-yocto-ubuntu
cd imx-yocto-ubuntu
repo init -u https://github.com/SoMLabs/imx-meta-somlabs-desktop -b mickledore -m imx-somlabs-desktop-6.1.36-2.1.0.xml
repo sync

System building may be configured for one of the available machine configurations:

• visionsom-8mm-cb-desktop - VisionCB-8M board family with VisionSOM-8Mmini modules
• titansbc-8mmini-desktop - TitanSBC-8Mmini board
• spacesom-8mplus-cb-desktop - SpaceCB-8Mplus board with SpaceSOM-8Mplus module

System building may be started by the following commands:

DISTRO=imx-desktop-xwayland MACHINE=<SELECTED_MACHINE> source imx-somlabs-desktop-setup-release.sh -b <BUILD_DIRECTORY>
bitbake imx-image-desktop

The system image is located in the imx-image-desktop-<SELECTED_MACHINE>.wic.zst file in the tmp/deploy/images/<SELECTED_MACHINE> directory. It should be extracted with the command:

unzstd somlabs-image-<SELECTED_MACHINE>.wic.zst

The instruction for the eMMC memory image installation may be found on the wiki page for corresponding module:
