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.

Raspberry Pi 4

In the next two sections, we go through the steps for baking and booting an image for the Raspberry Pi 4 board.

Baking for Raspberry Pi 4

To add this board support to our project, we need to include the meta-raspberrypi meta layer, which is the BSP layer with support for the Raspberry Pi boards, including the Raspberry Pi 4, but not limited to it. The meta layer can be accessed at

To create the source structure, please download Poky using the following command line:

git clone git:// -b kirkstone

After completing this, we must create the build directory we use for our builds and add the BSP layer. We can do this using the following command lines:

source oe-init-build-env build
bitbake-layers layerindex-fetch meta-raspberrypi

After we have the build directory and the BSP layers properly set up, we can start the build. Inside the build directory, we must...
