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.

However, when creating a product, it is very important to care and know about licenses and the kinds of licenses present in the product.

Poky keeps track of licenses, works with commercial and noncommercial licenses, and has a strategy to work with proprietary applications, at least during the development cycle.

Note

One important thing to know, at first, is that a recipe is released under a certain license, and it represents a project released under a different license. The recipe and the project are two different entities and they have different licensing, so the two different licenses must be considered part of the product.

In most recipes, information is a comment containing the copyright, license, and author name; this information pertains to the recipe itself. Then, there is a set of...
