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.

What is QEMU?

Quick EMUlator (QEMU) is a free, open source software tool that allows users to run multiple architectures on the same physical machine. It is a system emulator that can virtualize complete device hardware, including the CPU, memory, storage, and peripherals.

Using QEMU for testing and debugging can save time and effort during development. It allows developers to test their code in various simulated environments.

Among other things, the Yocto Project uses QEMU to run automated Quality Assurance (QA) tests on final images shipped with each release. Within the context of the Yocto Project, QEMU allows you to run a complete image you have built using the Yocto Project as another task on your build system. In addition, QEMU helps to run and test images and applications on supported Yocto Project architectures without having actual hardware.
