Overview of this book

The Yocto Project is a Linux Foundation workgroup, which produces tools (SDK) and processes (configuration, compilation, installation) that will enable the creation of Linux distributions for embedded software, independent of the architecture of embedded software (Raspberry Pi, i.MX6, and so on). It is a powerful build system that allows you to master your personal or professional development. This book presents you with the configuration of the Yocto Framework for the Raspberry Pi, allowing you to create amazing and innovative projects using the Yocto/ OpenEmbedded eco-system. It starts with the basic introduction of Yocto's build system, and takes you through the setup and deployment steps for Yocto. It then helps you to develop an understanding of Bitbake (the task scheduler), and learn how to create a basic recipe through a GPIO application example. You can then explore the different types of Yocto recipe elements (LICENSE, FILES, SRC_URI, and so on). Next, you will learn how to customize existing recipes in Yocto/OE layers and add layers to your custom environment (qt5 for example).

Raspberry Pi and a package manager


The basic building block of the Yocto Project is the generation of packages; therefore, it is possible to include a package manager to our Yocto distribution (similar to a Linux distribution, for example). Indeed, after the generation of the image (refer Chapter 2), it contains no package manager, so this means that our image is not updateable (similar to a firmware, for example).

The inclusion of a package manager in our distribution is done through this variable, if adding it to conf/local.conf:

EXTRA_IMAGE_FEATURES += "package-management" 

If adding to a recipe file (such as rpi-basic-image.bb), use this instead:

IMAGE_FEATURES += "package-management" 

With this addition, we have now an image with a package manager that is more flexible, updateable, and more industrial. Here's how to install a package with the opkg package manager:

$ opkg install package_name.ipk
