The Yocto Project - Inhouse training at the customers' place of business

Startdate



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.

Description

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 toolchain/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. Beagle Bone Black Rev. C -http://beagle-board.org/BLACK). After the training you will be able to download a docker image with Ubuntu 14.x and all dependencies pre-installed plus the examples in order to work with the course material in your 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 how to configure/build the GNU/Linux kernel and kernel drivers.

Prerequisites

  • Basic familiarity with using a GNU/Linux system (e.g. Ubuntu) as an end user in user space
  • Basic familiarity with a command line shell
  • Basic knowledge of user/kernel space programming with GNU/Linux
  • Intermediate C programming knowledge
    You actually need to have experience with Embedded GNU/Linux (kernel, userspace, root file system, tools) to follow this training.
  • It’s sufficient to know how to build the GNU/Linux kernel, kernel drivers in/out of tree and the fdt from the kernel side of things to follow this training
  • The trainings mentioned above can be delivered on-site and on-line

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 work-flow can be accommodated 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.

Delivery options

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

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

During the training we’ll provide laptops*), boards*)**), workbooks, reference books (in English)*)**), remote access to servers and boards**), screen-sharing**), audio-bridge**). 
The work-and reference books typically stay with the students after the training.
