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

Exploring Toaster


Toaster is a web interface for BitBake. The Yocto Project website describes it as follows:

"Toaster is an Application Programming Interface (API) and web-based interface to the OpenEmbedded build system, which uses BitBake. Currently, Toaster collects and presents information about your builds, which you can navigate and query using a web browser"

Installing the required packages for the host system

In order to use Toaster correctly on your preferred Linux distribution, you need to install Django and South:

$ sudo pip install django==1.6
$ sudo pip install South==0.8.4

Note

The pip command makes it easy to install Python modules, in the same way you install packages in a Linux distribution.

Running Toaster

Now that our system is ready to use Toaster, we only have to run it using the following command in order to launch the service:

$ source toaster start

This will give you the following output:

The system will start. Syncing... Creating tables ... Installing custom SQL ......
