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++.

Running your applications in the GDB

In this recipe, we will learn how to run a sample application in a debugger on a target system, as well as try out some basic debugging techniques.

GDB is an open source and widely used interactive debugger. Unlike most of the debuggers that come as part of Integrated Development Environment (IDE) products, the GDB is a standalone, command-line debugger. This means that it does not depend on any particular IDE. As you can see in the example, you can use a plain text editor to work on the code of your application, while still being able to debug it interactively, use breakpoints, view the content of variables and stack traces, and much more.

The user interface of the GDB is minimalist. You run with it in the same way as you work with a Linux console— by typing in commands and analyzing their output. This simplicity makes it extremely...
