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.

4.1/5 Stars
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.

Prerequisites
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 (the kinds of things you learn in LFD450: Embedded Linux Development). 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.
Reviews
Oct 2024
The course covered all topics and basics.
Oct 2024
I liked the hands-on labs, and the examples in the training manual.
Aug 2024
I liked the labs, that helped me better understand the build system, yocto/bitbake/poky and the structure of layers/configurations and recipes.
Jun 2024
John was a very good instructor, patient with the students' questions, able to help just about everyone with their problems, and he put everyone at ease.
Jun 2024
Starting out with no knowledge of Yocto environment, I can say I understand more of bitback, and am confident to build my own recipe.
Jun 2024
I think the labs, and having obtained the book, will be helpful. It was a lot of information, and I couldn't absorb it all, but with the material and the labs I can continue to learn on my own.
Jun 2024
I appreciated the detail devoted to all the different aspects of working with Yocto. I have used Yocto before, but even in the early part of the training going over the foundations, I found a lot of useful tips and tricks I didn't know about.
Jun 2024
That it was up-to-date with the most recent LTS release of yocto, even though that has only recently been released. That takes a lot of work, thank you for doing that.
