Introduction

# Course Review: Cortex-M Software Development Fundamentals on Coursera In the rapidly evolving world of embedded systems, proficiency in software development for ARM Cortex-M devices is becoming increasingly indispensable. Coursera's "Cortex-M Software Development Fundamentals" course offers a comprehensive introduction to the core concepts and techniques essential for developing software tailored to these microcontrollers. ## Overview The course targets both novice and experienced programmers seeking to enhance their skills in ARM software development. Over the duration of the course, participants will explore critical software development topics, including working with Arm C/C++ compilers, Arm debug tools, and optimizing code for performance and size. One of the key highlights is the focus on the Common Microcontroller Software Interface Standard (CMSIS), which provides a consistent framework for software targeting Cortex-M devices. ## Syllabus Breakdown ### 1. Course Introduction The course starts with an engaging introduction that sets the stage for what participants can expect. It lays the groundwork for understanding the essentials of ARM software development, emphasizing both performance and code size optimization. Instruction on compiler and linker options is particularly beneficial, ensuring developers can navigate both the Arm Compiler for Embedded and the GNU toolchain effectively. ### 2. Compiler & Linker Fundamentals This module dives deeper into the functionality and options available in compilers and linkers. Understanding these tools is crucial for developers working within the ARM ecosystem, as they dictate how code is compiled and linked, ultimately affecting performance and efficiency. ### 3. Debug & Trace The "Debug & Trace" module is an invaluable section that covers the debugging and tracing features available in the Armv8-M Mainline architecture. This part of the course enables developers to uncover and resolve issues within their software, ensuring robust and reliable microcontroller applications. ### 4. Booting & Initialization Participants will learn about essential startup code in the "Booting & Initialization" module. It's vital for developers to understand how to configure and initialize the processor and system before the execution of the main function in C programming. This knowledge is foundational for any embedded systems project, making the module particularly relevant. ### 5. Cortex-M Walkthrough In the "Cortex-M Walkthrough" module, learners engage with the Tarmac trace tool from Fast Models, providing insights into the lifecycle of a Cortex-M3 device. The walkthrough covers everything from system reset to triggering interrupts using the Nested Vectored Interrupt Controller (NVIC). Though focused on the Cortex-M3, the learnings are broadly applicable to any Armv7-M or Armv8-M device. ## What Makes This Course Stand Out? One of the most compelling aspects of this course is its combination of theoretical knowledge and practical application. The hands-on experience with debugging tools and the emphasis on real-world applications make it suitable for learners who prefer a more interactive learning style. The course's structure accommodates different learning paces, allowing participants to digest the material effectively. ## Recommendations The "Cortex-M Software Development Fundamentals" course is highly recommended for: - **Aspiring Embedded Systems Engineers**: If you are looking to kick-start your career in embedded systems, this course provides the foundational knowledge you need. - **Experienced Developers**: Those already in the field will benefit from a refresher on Cortex-M architecture as well as effective programming practices. - **Students and Educators**: Those studying or teaching embedded systems can utilize this course as part of a larger curriculum. Overall, this course is a robust resource for anyone looking to deepen their understanding of ARM Cortex-M software development. Its well-structured content, practical approach, and industry-relevant insights make it a worthy investment for your career in embedded systems programming.

Syllabus

Course Introduction

This course delves into software development topics such as working with Arm C/C++ compilers and Arm debug tools to optimize your software, whether it's for performance or code size. This course also looks more closely at the Common Microcontroller Software Interface Standard and how it helps ensure that software targeted at Cortex-M devices can be written using a consistent approach.This module describes the essential compiler and linker options required in order to develop applications targeted at different Arm embedded systems. The presentation includes information about Arm Compiler for Embedded and the GNU toolchain.

Compiler & Linker Fundamentals

Debug & Trace

This module describes the debug and trace features available in the Armv8-M Mainline architecture.

Booting & Initialisation

The Booting and Initialization module takes you through essential startup code that can ensure that the processor and system are configured and initialised appropriately before the 'main' function is reached in the C program.

Cortex-M Walkthrough

This module introduces Tarmac trace from Fast Models, and uses that to walk through everything a Cortex-M3 device would do if used with CMSIS code from Reset to the main() function, to triggering an interrupt using the NVIC. Although the module is related to a Cortex-M3 device, the details presented also apply to any Armv7-M / Armv8-M device, acting as a recap of all the content covered in this M-profile course.
