INSTRUCTOR-LED COURSE

Embedded Linux Platform Development with Yocto Project (LFD460)

In this instructor-led course, you’ll obtain a solid understanding of how to build a repeatable embedded Linux target using the Yocto Project. In addition to learning the build system, you will learn about more advanced tools like toaster, devtool, wic, eSDK, and eclipse IDE integration. This course builds on the Embedded Linux topics learned in the LFD450 class.

Who Is It For

This course is primarily intended for experienced embedded Linux engineers who are interested in learning how to repeatably build an embedded Linux system. This course assumes you have basic knowledge of Embedded Linux systems such as building and install boot loaders, kernels and user space software. You should also be familiar with building code from the command line, basic Linux utilities and text editors. Some experience with Python is helpful but not required.

What You’ll Learn

In this Yocto training course you will learn how to use the Poky and Bitbake build process, with its recipes and layers to customize Linux kernel and packages for a custom embedded application, how to build Linux on an embedded board, how to use emulators for verification, how to create board support packages (BSP) for target hardware, and more.

What It Prepares You For

This course prepares you to take advantage of the Yocto Project – the open source collaboration effort that provides templates, tools and methods to help you create and maintain custom Linux-based systems for embedded products regardless of the specific hardware architecture.
