This article guides you to easily build Linux OS images for e-con systems™ eSOMiMX6 boards on multiple platforms – Linux, Windows, mac.

Building an OS Image for the System on Module might become a very time-consuming work. That too only when I want very minimal changes to the OS image, the time and effort that it requires for that minimal change might become a  road block.

So here is an easy way to build Linux OS images for e-con Systems™ eSOMiMX6 SOMs, our most popular system on module that runs on Freescale i.MX6.

There are 2 advantages you get if you follow this build method,

  1. Stop going through the cumbersome process of Yocto build system setup for Linux and save time
  2. Build a Linux OS image from any system that you have – Windows, Linux or Mac

I think the second advantage is particularly interesting as I know many of you have made your systems dual boot just to build the OS image in Linux

Now let’s get directly get to work and explain how you should do it and using what you should do it…

Introducing…. DOCKER .. (drum rolls please..)


Docker is a neat tool that allows you to have a consistent environment for developers and production build machines. Docker enables users to run their containers wherever they please either in a Cloud or on-premise and in any OS like Linux, Windows and mac.

We’ve created a docker repository that provides a quick and easy way for creating rootfs and kernel for our eSOMiMX6 Solo, Quad & micro SOMs that can run on multiple platforms – Linux, Windows & mac using Docker. Please visit our developer website for detailed instructions to install docker on multiple platforms and also docker repository information.

The container we’ve created gives you everything you need as soon as your eSOMiMX6 board arrives. Using this container for builds allows team members to use whatever Linux distribution or OS they want on their workstations, but all have access to a common build environment.

First build – Save 4-5 hours!!

Apart from maintaining the build environment and allowing the developers to have workstations with any OS (Linux, Windows, mac) or Linux distribution, we’ve also reduced the build time of eSOMiMX6 rootfs and the kernel.

Yocto build needs to download hundreds of packages to build the kernel and the rootfs. We’ve added these packages in our container. This avoids downloading packages during the builds.

To validate docker for Yocto builds, we tested the Docker and the legacy approach.

We found out that we were able to run the same Docker image on Linux, Windows and mac machines.

Also as mentioned earlier, build time was considerably reduced by 4~5 hours when compared to legacy approach.


E-con’s docker container allows you to maintain build environment, allows developers to have their workstations with any Linux distribution or OS (Linux, Windows, mac) and also reduces the setup and the build time which will certainly reduce the build $$$.
