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.

When is choosing real hardware preferable?

There are several situations where it may be more practical, and even required, to use real hardware instead of QEMU for testing and debugging, such as the following:

  • When the software relies on specific hardware features, for example, a particular Video Processing Unit (VPU) or Graphics Processing Unit (GPU) feature
  • When evaluating the software performance, QEMU may not be able to replicate the performance of real hardware

While QEMU can be a valuable tool for testing and debugging software, it is not always a perfect substitute for real hardware.
