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).

Summary


In this final chapter of the book, we repeated the techniques we learned throughout the book. This was done by creating a home automation project, which can wirelessly turn on and off lamps in your home with help from a Raspberry Pi and a web browser, using your smartphone as the remote, for example.

For our home automation project, we improved some of the examples used earlier in the book, such as the GPIO control binary and the Node.js examples. By evolving them, we revised how to modify existing recipes by appending them with new files or patching the old ones. The project also required you to revise how to create and integrate external layers. Further on, the chapter looked closer at some techniques and introduced you the usage of a specific package list in your project and how to use a serial connection and SSH to easily access and debug your Raspberry Pi. In order to complete the project, you were required to learn more deeply how the GPIO header and pins for the Raspberry Pi...
