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).

Contributing to open source projects


Open source projects are heavily dependent on what people give back to the project, for example, submitting error reports if they find faults in the software or helping the project with solving bugs or developing new features. The community behind an open source project is often limited and doesn't have the resources to do everything by itself. Large projects such as the Linux kernel, OpenStack, and the Yocto Project have large companies behind them, allocating resources for helping out with those projects. The reason for this is obvious: the companies are using the project in commercial products and it's in their interest to make sure that the product has good progress. Many companies also use their own version of the project and want to contribute features and bug fixes in order to decrease the integration cost.

Tip

When working with open source, the term upstream is used from time to time. Upstream could basically be summarized as the original source...
