Linux Embedded & Yocto training – ONLINE

Online training

Our most popular ‘comboonline course because in just five afternoons you can learn everything you need to begin to cross compile the Linux Kernel for an ARM card and use Yocto Project to generate recipes and custom layers.

Basic course aimed at beginners with a minimum knowledge of Linux, it provides the information needed to configure and cross-compile the u-boot Bootloader and the Kernel.

This course also provides the information needed to configure and use Yocto Project (and Openembedded), git and bitbake by creating an embeddded Linux distribution from scratch. Management of recipes in overlays with custom layers.

Learn to build and manage embedded Linux systems with the Yocto Project and OpenEmbedded.
If you want to not waste time performing time-consuming tasks during the course, this intensive course is perfect for you.
In order to save time, some sections are shortened or skipped, such as downloading the packages and the long initial compilation, depending on the needs and interests of the participants.

Yocto Project Participant

Equipment required

Each participant must have a Laptop on which a Virtual Machine provided by the teacher at the beginning of the course will be installed. All the necessary material is provided by Koan except the PC. Therefore participants must have their own laptop with:

  • Laptop PC with at least 4 GB of RAM and 40 GB of free disk space.
  • Virtual Box installed (downloadable from here).
  • We will work with Lubuntu Desktop 18.04 (64 bit). (We don’t support other distributions, because we can’t test all possible versions).
  • Internet connection (direct or through the company proxy).
  • For security reasons it is necessary that each participant backup their computer before the course.

Hardware used

The practical exercises will be run by the teacher on a real board with an ARM CPU during the course.
The board used depends on the course you are attending.
Verify this detail in the page dedicated to the specific training course you are going to attend.

Thanks to the portability of Linux and Yocto Project, all the exercises performed will be applicable to any other type of card. For example:

  • NXP – i.MX6, i.MX7, i.MX8
  • ST Microelectronics – STM32
  • Intel – x86
  • NVIDIA –  Jetson NANO, Xavier NX

During the online course some of the practical exercises will be carried out with Yocto Project using a Qemu ARM virtual hardware. In this way you can directly experiment the development workflow on your Linux Virtual Machine (provided by the trainer).

Qemu ARM


To get the best results from this course it is advisable to know the following topics:

  • Basic Linux knowledge
