Overview of this book

Developing applications for embedded systems may seem like a daunting task as developers face challenges related to limited memory, high power consumption, and maintaining real-time responses. This book is a collection of practical examples to explain how to develop applications for embedded boards and overcome the challenges that you may encounter while developing. The book will start with an introduction to embedded systems and how to set up the development environment. By teaching you to build your first embedded application, the book will help you progress from the basics to more complex concepts, such as debugging, logging, and profiling. Moving ahead, you will learn how to use specialized memory and custom allocators. From here, you will delve into recipes that will teach you how to work with the C++ memory model, atomic variables, and synchronization. The book will then take you through recipes on inter-process communication, data serialization, and timers. Finally, you will cover topics such as error handling and guidelines for real-time systems and safety-critical systems. By the end of this book, you will have become proficient in building robust and secure embedded applications with C++.

Cross-compilation

We have already learned that the environment for embedded development consists of two systems: the build system, where you write and build code, and the host system, which runs the code.

We now have two virtualized environments set up:

  • Ubuntu Linux in a Docker container, which will be our build system
  • QEMU running Raspbian Linux, which will be our host system

    In this recipe, we will set up the cross-compilation tools required to build Linux applications for the ARM platform and build a simple Hello, world! application to test the setup.

    Getting ready

    To set up the cross-compilation toolkit, we will need to use Ubuntu Linux, which we set up in the Setting up the build system in a Docker container...
