Overview of this book

The Yocto Project is the industry standard for developing dependable embedded Linux projects. It stands out from other frameworks by offering time-efficient development with enhanced reliability and robustness. With Embedded Linux Development Using Yocto Project, you’ll acquire an understanding of Yocto Project tools, helping you perform different Linux-based tasks. You’ll gain a deep understanding of Poky and BitBake, explore practical use cases for building a Linux subsystem project, employ Yocto Project tools available for embedded Linux, and uncover the secrets of SDK, recipe tool, and others. This new edition is aligned with the latest long-term support release of the aforementioned technologies and introduces two new chapters, covering optimal emulation in QEMU for faster product development and best practices. By the end of this book, you’ll be well-equipped to generate and run an image for real hardware boards. You’ll gain hands-on experience in building efficient Linux systems using the Yocto Project.

Powering flexibility with layers

Poky contains metadata spread over configuration definition files such as machine and distro files, classes, and recipes, covering everything from simple applications to full graphical stacks and frameworks. There are multiple places that BitBake can load metadata collection from, which are known as metadata layers.

The biggest strength of using layers is the ability to split metadata into logical units, which enables users to pick only the metadata collection needed for a project.

Using metadata layers enables us to do the following:

  • Improve code reuse
  • Share and scale work across different teams, communities, and vendors
  • Increase the Yocto Project community’s code quality, as multiple developers and users focus together on a particular metadata layer that is of interest to them

We can configure the system for different reasons, such as the need to enable/disable a feature or change build flags to enable architecture...
