Embedded GNU/Linux Systems Architecture


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.


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.


  • 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 space/application development with GNU/Linux 
  • Basic knowledge concerning embedded processors and development boards 
  • Basic C programming knowledge 
  • …and/or no fear to learn the above… 

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.
