Overview
The Yocto Project is an open-source collaboration focused on embedded Linux development.
The purpose of this article is to show how to get Yocto Image with support for the UCM-iMX8M-Mini System-on-Module.
Yocto Environment Setup
Yocto host requirements are listed on the Yocto official site Linux Distributions to be used on a host are listed ibid
In order to get NXP Yocto BSP building environment please issue the following commands. More detailed instructions can be found at the NXP readme file
repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-hardknott -m imx-5.10.35-2.0.0.xml wget --directory-prefix .repo/manifests https://raw.githubusercontent.com/compulab-yokneam/meta-bsp-imx8mm/rel_imx_5.10.35_2.0.0-stable/scripts/imx-5.10.35_2.0.0_compulab.xml repo init -m imx-5.10.35_2.0.0_compulab.xml repo sync
The Compulab meta-layer consists of meta-compulab directory, that provides support for UCM-iMX8M-Mini and other Compulab i.MX based machines and contains recipes for U-boot and Linux kernel.
Image Building
This section provides information about building UCM-iMX8M-Mini images.
Create Build Environment
- Issue Compulab Setup Script:
export MACHINE=ucm-imx8m-mini MACHINE=ucm-imx8m-mini DISTRO=fsl-imx-xwayland source ./compulab-setup-env -b build-xwayland
You will be asked regarding options of the image you are configuring.
Building the Images
The Yocto Project build uses the bitbake command.
- To build a Compulab image with GUI use the command below:
bitbake -k compulab-ucm-imx8m-mini
- To build a minimal Linux image use the command below:
bitbake -k core-image-full-cmdline
- To re-build only the Linux kernel use the command below:
source setup-environment build-xwayland bitbake -c cleansstate linux-imx bitbake -k linux-imx
- To re-build only the u-boot bootloader and boot image use the command below:
source setup-environment build-xwayland bitbake -c cleansstate imx-boot u-boot-imx bitbake -k imx-boot u-boot-imx
Installation
The resulting images are located in the build directory: build-xwayland/tmp/deploy/images/${MACHINE}
ucm-imx8m-mini.wic.bz2 | complete SD card image |
ucm-imx8m-mini.tar.bz2 | root FS tree |
imx-boot-ucm-imx8m-mini-sd.bin-flash_evk | boot loader binary |
Image | kernel binary |
modules-ucm-imx8m-mini.tgz | kernel modules tree |
ucm-imx8m-mini.dtb | device tree binary |
To deploy the built image follow the SD card installation instructions
