Overview

This 5-day training class uses hands-on exercises combined with instruction to illustrate the concepts of embedded GNU/Linux. It is desinged 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.

Objectives

To provide an understanding of the essentials of embedded GNU/Linux, how the bits and pieces fit together and where to find more information. Hands-on exercises provide you with the necessary practical experience to go ahead and develop your own embedded GNU/Linux system after completing this training successfully.
