The Insider's Guide to Arm Cortex-M Development

By: Zachary Lasiuk, Pareena Verma, Jason Andrews

Overview of this book

Cortex-M has been around since 2004, so why a new book now? With new microcontrollers based on the Cortex-M55 and Cortex-M85 being introduced this year, Cortex-M continues to expand. New software concepts, such as standardized software reuse, have emerged alongside new topics including security and machine learning. Development methodologies have also significantly advanced, with more embedded development taking place in the cloud and increased levels of automation. Due to these advances, a single engineer can no longer understand an entire project and requires new skills to be successful. This book provides a unique view of how to navigate and apply the latest concepts in microcontroller development. The book is split into two parts. First, you’ll be guided through how to select the ideal set of hardware, software, and tools for your specific project. Next, you’ll explore how to implement essential topics for modern embedded developers. Throughout the book, there are examples for you to learn by working with real Cortex-M devices with all software available on GitHub. You will gain experience with the small Cortex-M0+, the powerful Cortex-M55, and more Cortex-M processors. By the end of this book, you’ll be able to practically apply modern Cortex-M software development concepts.

Implementing safe software

Software development for embedded systems with safety requirements can be challenging. Safety-critical software requires special procedures during design and development. Safety analysis needs to be performed on all the software components in the project, and extensive validation needs to be done to meet the safety standards for your product. Using safety-certified software components in your application can ease your development effort.

A popular set of embedded software components that are qualified for the most safety-critical applications is Arm Functional Safety Run-Time System (FuSa RTS). It applies across the automotive, industrial, and medical industries. The specific components of Arm FuSa RTS are summarized here:

  • FuSa RTX RTOS: Deterministic RTOS that supports complex real-time applications. Enables threads, timers, memory management, and more.
  • FuSa Event Recorder: Provides API function calls that annotate events in code that can...
