Course Objectives

To provide an understanding of the essentials to utilize the Yocto Project on top of your firm knowledge about Embedded GNU/Linux, the GNU/Linux kernel and friends. We’ll see how a BSP/framework maintainer would use the Yocto Project as well as developers who might not even want/need to know they are using it.

Introduction

This four day training combines theory with hands-on exercises in order to introduce the Yocto Project.
It answers frequently asked questions like:

  • Is it really necessary to use another version of the tool-chain/libraries/packages for each and every GNU/Linux project and an top of that to follow a different work-flow?
  • Can you ensure that the development environment is identical for all developers/suppliers and that you can still produce identical builds like today in 10+ years from now?
  • Can the YP help find out under what software licenses the packages you use are licensed?
  • ... and much more

Hands-on sessions are performed on target hardware (e.g. phyBOARD-Mira i.MX 6 Quad - Full Featured). After the training the students will be able to download a docker image with Ubuntu 16.x and all dependencies pre-installed plus the examples in order to work with the course material in their own labs. Please note that this is not an introductory course to Embedded GNU/Linux like the one we offer here. You should already know how Embedded GNU/Linux works and maybe you even configured/built the Linux kernel for some of your projects.

Who should attend?

You already use GNU/Linux for your projects and have probably heard about the Yocto Project, but did not dare to have a closer look into it, or had difficulties using it. You don’t know whether and how your daily workflow can be accomodated in the YP and generally find the YP rather complicated. Why do we need all this since up to know everything was (supposedly) much easier? After the training you should be able to decide whether you need the YP or not. The workshop is aimed at software-, development-, system engineers, testers, administrators, engineers and other parties interested in the YP, with a solid knowledge of Embedded GNU/Linux.

Prerequisites

Delivery Options

All the training material is English, but the presentation of it can be in English or in German, as you wish.

  • on-site - instructor driven *)
  • on-line - instructor driven **)
  • on-site/on-line combination - instructor driven *)**)

We’ll provide laptops*), boards*)**), workbooks and reference books (in English)*)**), remote access to servers and boards **), screen-sharing **), audio-bridge **). For possible training delivery options check here and/or ask here.
