Agenda for Training course Embedded GNU/Linux Systems Architecture

This 5-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. We describe the philosophy, concepts and commands necessary to make effective use of GNU/Linux through a combination of theory and on-the-job training. Don't reinvent the wheel, but learn from our experience and take home a working knowledge of GNU/Linux and the ability to use it effectively in your own embedded development project.

Prerequisites

• Basic familiarity with using a GNU/Linux system as an end user
• Basic familiarity with a command line shell
• Basic C programming knowledge

Who should attend?

Those who are interested in or tasked with developing embedded GNU/Linux like software engineers, field engineers, (project) managers.
