EMBEDDED LINUX DEVELOPMENT WITH YOCTO PROJECT (LFD460)

COURSE DESCRIPTION

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. 

LEARNING OBJECTIVES

This course builds on the Embedded Linux topics learned in the LFD450 class. 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.
