imx6_buildroot

SolidRun's i.MX6 based build scripts

Introduction

Main intention of this repository is to build a buildroot based build environment for i.MX6 based products.

The build script provides ready to use images that can be deployed on a micro SD card.

Source code versions

• U-boot 2018.11
• Linux kernel 5.18
• Buildroot 2020.08.1

Building Image

The build script will check for required tools, clone and build images and place results in output/ directory.

Docker build (recommended)

• Build the Docker image (Just once):

docker build --build-arg user=$(whoami) --build-arg userid=$(id -u) -t imx6 docker/

To check if the image exists in you machine, you can use the following command:

docker images | grep imx6

• Run the build script:

docker run --rm -it -v "$PWD":/imx6_build/imx6_buildroot imx6:latest /bin/bash
# Run the build script
cd /imx6_build/imx6_buildroot && ./runme.sh

Note: run the above commands from imx6_buildroot directory

To Delete all containers:

docker rm -f $(docker ps -a -q)

Native Build

Simply:

./runme.sh

Deploying

In order to create a bootable SD card, plug in a micro SD into your machine and run the following, where sdX is the location of the SD card got probed into your machine -

umount /media/<relevant directory>
sudo dd if=output/microsd-<hash>.img of=/dev/sdX

NOTE

If you use HummingBoard CBI Carrier board, you should change the U-Boot environment is_cbi for 'no' to 'yes' to enable the RS485 & CanBus interface, you can use the U-boot commands below:

setenv is_cbi yes; saveenv; boot
