Overview
The Yocto Project is an open-source project for building embedded Linux systems. It uses a build host based on OpenEmbedded (OE), which uses the BitBake tool, to construct complete Linux images
In this instructor-led, live training, participants will learn how to create a build system for embedded Linux based on Yocto Project.
By the end of this training, participants will be able to:
- Understand the fundamental concepts behind a Yocto Project build system, including recipes, metadata, and layers.
- Build a Linux image and run it under emulation.
- Save time and energy building embedded Linux systems.
Format of the course
- Part lecture, part discussion, exercises and practice
Other Options:
- Buildroot is a simpler alternative to the Yocto project
- To request a customized training for this course, please contact us to arrange.
Requirements
- The participant must have built a kernel at least once for a traditional desktop (non-embedded) Linux system.
- Knows what components the Linux userspace on a desktop system is composed of.
- Knows how to generate and use patches.
- Must be able to explain what is GNU Make, Autotools, what other build systems exist.
- Ideally, maintains at least one Linux package, either as an upstream author, or in any traditional Linux desktop distribution.
- Prior experience with embedded development is not required, and is not a substitute for the knowledge about traditional Linux desktops specified above.
Audience
- Developers
- System engineers
- Test engineers
- System administrators
