Embedded Linux: Building a System from the Ground Up

• Experience with Linux.

Audience

• System engineers

Embedded Linux, with its low cost, ease of customization, and compatibility with many types of microprocessors has become the natural choice for powering a wide range of devices such as smart phones, tablets, set-top boxes and MP3 players.

In this instructor-led, live training participants will learn step-by-step how to build an embedded Linux system from the ground up. From building a minimalistic kernel to configuring the bootup and initialization processes, participants will learn the tools, techniques and mindset needed to deploy a fully functional embedded Linux system.

For remote trainings, QEMU will be used to emulate the hardware. Other platforms, including real hardware devices, can be considered on a case by case basis.
