The knowledge of the trainer. He was able to answer all of my questions, even questions about our platform. He also continued to help until we all understood the material.

James O'Donnell - Tennant Company
Course - Embedded Linux Kernel and Driver Development

I understood the process of the operating system and how do we link all factors together information of network as well so now I have an obvious and full picture about what is going on these computers how they communicate with each others ultimately gained knowledge about the most important operating system which is Linux and how do we implement our own embedded Linux

Course Objectives

To provide an understanding of the essentials of embedded GNU/Linux, how the bits and pieces fit together. What components are needed to build an embedded GNU/Linux system, where to get them from and how to configure/build/install them? Where to get help from? What about those software licenses? Hands-on exercises provide you with the necessary practical experience to go ahead and develop your own embedded GNU/Linux systems after completing this training successfully.

Description

This five day training class uses hands-on exercises combined with instruction to illustrate the concepts of embedded GNU/Linux. It is designed to bring you quickly up to speed. The philosophy, concepts and commands necessary to make effective use of GNU/Linux are described through a combination of theory and on-the-job training.

Don't reinvent the wheel, but learn from an experienced trainer and take home a working knowledge of GNU/Linux and the ability to use it effectively in your own embedded development project.

Who should attend?

Managers, project managers, software-, hardware-, development-, systems engineers, testers, administrators, technicians and other parties interested in the technology, who want to understand as quickly as possible how Embedded GNU/Linux works. You must use GNU/Linux or you have to luxury to decide whether it makes sense to use it or not. Maybe you already tried to use Embedded GNU/Linux, but are not quite sure that you did everything the right way. You currently use a different operating system and wand to figure out whether GNU/Linux might better and/or cheaper.

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

The Yocto Project - An Overview - hands-on

28 Hours

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?

Hands-on sessions are performed on target hardware (e.g. Beagle Bone Black Rev. C - http://beagleboard.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. You should already know how Embedded GNU/Linux works and how to configure/build the GNU/Linux kernel and kernel drivers.

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.
