This course is designed for anyone wishing to learn about the range of Cortex-M processors and the different resources that can help you with your Cortex-M project. The course begins with a bit of history about Arm processors and the Arm architecture, covering the differences between the M-profile and other architecture profiles like A-profile and R-profile. This course is suitable for beginners or people without an engineering or computer science background. The introductory material also sets

Armv8-M Architecture Fundamentals (Coursera)

https://www.coursera.org/learn/armv8-m-architecture-fundamentals

The course includes fundamental architecture topics that are key to understanding how any Cortex-M processor functions internally. The course focuses specifically on the Armv8-M version of the Arm Architecture, which processors like the Cortex-M33 and Cortex-M55 are based on. However, even if you're working with older processors based on earlier versions of the architecture, like Armv6-M or Armv7-M, a lot of the information is mostly still very relevant and useful.

Cortex-M Software Development Fundamentals (Coursera)
