Embedded Linux Workshop

Overview

  • The course is designed for individuals with experience in software design. A Basic knowledge of a programming language such as C++ or Java will be helpful. Background in embedded system development will be a plus.
  • The application of the Linux Operating system in embedded systems design is exploding. More and more new and unique applications are being designed and deployed everyday. Programmers and hardware designers will benefit from this 4 day opportunity to develop real world embedded Linux skilled through hands on exercises, labs, and design projects.

What you will learn

Learn practical, hands on Embedded Linux skills with real world expert instructors who've "been there".  Gain insights and up to date expterise in Embedded Linux.

Who Needs to Attend

Software and hardware developers interested in embedded Linux design and development.  This course is intended for HW and SW developers, it is not suitable for Linux Sys Admins and IT personnel.

Prerequisites

sw development experience, ideally you have reasonable familiarity with at least one generic Linux distro, however this is not a manditory requirement.
