Embedded Linux

Overview

This course offers a comprehensive understanding of embedded Linux systems, covering essential topics such as kernel architecture, cross-compilation, bootloaders, root file system creation, and the Yocto Project. Participants will gain hands-on experience using platforms like QEMU and Beaglebone Black. Additionally, the course introduces the concepts of hypervisors with a focus on Xen for virtualization. Ideal for entry-level engineers, this training is designed to build a strong foundation in embedded Linux development.

Objectives

By the end of this course, leaner will be able to:

  • Understand the architecture and role of the Linux kernel in embedded systems

  • Configure, build, and cross-compile a Linux kernel for target platforms

  • Comprehend bootloader concepts and manage boot processes

  • Create and customize a root file system for embedded devices

  • Develop custom embedded Linux images using the Yocto Project

  • Gain an introductory understanding of virtualization with Xen hypervisor
