Yocto Project ( yoctoproject | 28 hours )

• 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

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.
