Embedded Linux Development Using Yocto Project Cookbook - Second Edition

By: Alex Gonzalez

Overview of this book

The Yocto Project has become the de facto distribution build framework for reliable and robust embedded systems with a reduced time to market.You'll get started by working on a build system where you set up Yocto, create a build directory, and learn how to debug it. Then, you'll explore everything about the BSP layer, from creating a custom layer to debugging device tree issues. In addition to this, you’ll learn how to add a new software layer, packages, data, scripts, and configuration files to your system. You will then cover topics based on application development, such as using the Software Development Kit and how to use the Yocto project in various development environments. Toward the end, you will learn how to debug, trace, and profile a running system. This second edition has been updated to include new content based on the latest Yocto release.

Adding Python applications

Python is a widely-used, interpreted high-level programming language. Poky has support for building both Python 2 and Python 3 applications, and includes a small set of Python development tools in the meta/recipes-devtools/python directory. A wider variety of Python applications are available in the meta-python layer included as part of meta-openembedded, which you can optionally add to your conf/bblayers.conf.

Getting ready

The standard tool for packaging Python modules is Distutils, which is included for both Python 2 and Python 3. Poky includes the distutils class (distutils3 in Python 3), which is used to build Python packages that use distutils. An example recipe in meta-python that uses the distutils class is meta-python/recipes-devtools/python/, shown next:
