Embedded Linux Development using Yocto Projects - Second Edition

By: Otavio Salvador, Daiane Angolini

Overview of this book

Yocto Project is turning out to be the best integration framework for creating reliable embedded Linux projects. It has the edge over other frameworks because of its features such as less development time and improved reliability and robustness. Embedded Linux Development using Yocto Project starts with an in-depth explanation of all Yocto Project tools, to help you perform different Linux-based tasks. The book then moves on to in-depth explanations of Poky and BitBake. It also includes some practical use cases for building a Linux subsystem project using Yocto Project tools available for embedded Linux. The book also covers topics such as SDK, recipetool, and others. By the end of the book, you will have learned how to generate and run an image for real hardware boards and will have gained hands-on experience at building efficient Linux systems using Yocto Project.

Pheew! We got it done! Now you should know the basics of the Yocto Project build system and be capable of extending your knowledge about it to cover other areas with much less hassle. We tried to cover the most common tasks in daily work using the Yocto Project, and there are few things you might want to practice:

  • Creating bbappend files to apply patches or do other changes on a recipe
  • Make your custom images
  • Change the Linux kernel configuration file (defconfig)
  • Change the busybox configuration and include the configuration fragments to add or remove a feature in a layer
  • Add a new recipe for a package
  • Make a product layer with your product-specific machines, recipes, and images

Remember, the source code is the ultimate knowledge source, so use it. When looking for how to do something, finding a similar recipe buys you a lot of time testing different approaches to solve the problem.

Eventually, you’ll likely see yourself in a position to fix or enhance something on OpenEmbedded-Core,...
