Yocto Project training – ONLINE
Our most popular ‘Yocto Project‘ online course because in just three afternoons you can learn everything you need to begin to use Yocto Project to generate recipes and custom layers.
This course provides all the information needed to manage a project with Yocto Project and Openembedded.
You will learn to generate an embedded BSP for Linux and develop embedded applications.
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.

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.
The practical exercises will be run by the teacher on a BeagleBone Black with a Cortex ARM CPU during the course.
while the practical exercises will be carried out with Yocto Project using a Qemu ARM virtual hardware
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
To get the best results from this course it is advisable to know the following topics:
- Knowledge of embedded Linux as described in our embedded Linux training
- Basic knowledge of the command line shell
- Programming knowledge C
- Experience with Embedded GNU / Linux (kernel, user space, root file system, tools)
- Practice of Unix or GNU / Linux commands
