Training Description

This self-paced Embedded Linux technical training course describes how to apply Linux, the free, Open Source operating system, to embedded computing devices. Topics include: a brief introduction to Linux and the Open Source philosophy, installing a cross-development environment, using the Eclipse IDE, running and debugging applications on an embedded target, configuring and building the Linux kernel, booting the target, and network applications.

Training Objective

Upon completing this Embedded Linux self-paced training course, you will understand how to:

• Set up a cross development environment on a Linux workstation
• Create, build, and debug applications on a target board using the Eclipse IDE
• Write multi-threaded and networked applications
• Configure and build the Linux kernel

Prerequisites

Attendees should be very comfortable programming in C. Some familiarity with Linux is helpful, but not essential.

As this is very much a hands-on class, you’ll get more out of the class if you have the target hardware on which the examples are run. This would be the Embedded Linux Learning Kit from Intellimetrix, which is offered at a reduced price to Go Gogh and Dash Course students. Go to www.intellimetrix.us/gogogh.
