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++.

Working with core dumps

In the first recipe, we learned how to nail down the root cause of a crashing application using an interactive command-line debugger. However, there are situations when applications crash in the production environment, and it is impossible or impractical to reproduce the same issue running the application under the GDB on a test system.

Linux provides a mechanism to help with the analysis of crashing applications even when they are not run from the GDB directly. When an application is terminated abnormally, the operating system saves the image of its memory into a file named core. In this recipe, we will learn how to configure Linux to generate core dumps for crashing applications, and how to use the GDB for their analysis.
