Embedded Linux Development Using Yocto Project - Third Edition

By: Otavio Salvador, Daiane Angolini

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.

The alliance of the OpenEmbedded project and the Yocto Project

The OpenEmbedded project was created around January 2003 when some core developers from the OpenZaurus project started to work with the new build system. Since its beginning, the OpenEmbedded build system has been a task scheduler inspired and based on the Gentoo Portage package system named BitBake. As a result, the project quickly grew its software collection and the supported machine list.

Due to chaotic and uncoordinated development, it was challenging to use OpenEmbedded in products that demand a more stable and polished code base, which is how Poky distribution was born. Poky started as a subset of the OpenEmbedded build system, and had a more polished and stable code base across a limited set of architectures. Additionally, its reduced size allowed Poky to develop highlighting technologies, such as IDE plugins and Quick Emulator (QEMU) integration, which are still in use.
