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.

Using the X Windows system

The X Windows system provides the framework for a GUI environment-things like drawing and moving windows on the display and interacting with input devices like the mouse, the keyboard, and touchscreens. The protocol version has been v11 for over two decades, so it also known as X11.

Getting ready

The reference implementation for the X Windows system is the X.Org server, which is released under permissive licenses such as MIT. It uses a client/server model, with the server communicating with several client programs, serving user input, and accepting graphical output. The X11 protocol is network-transparent, so that clients and server may run on different machines with different architectures and operating systems. However, mostly they both run on the same machine and communicate using local sockets. User interface specifications, such as buttons or menu styles, are not defined in X11, which leaves it to other window manager applications that are usually part of desktop...
