Yocto for Raspberry Pi

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).

Mastering Baking with Hob and Toaster

Deploying the raspberry-packt-image.bb image


Now comes the time when we can test our image and check its operation. To do this, we have to launch usual bitbake command, but this time with an argument-the name of our image, raspberry-packt-image:

$ bitbake raspberry-packt-image
Loading cache: 100% |########################################################################################################################################################################| ETA:  00:00:00

Now, we have a 100% custom environment ( layer , recipe , and image ).
