Arm Cortex-M7 Software Design

Standard Level - 4 days

This course is designed for engineers developing software for platforms based around the Arm® Cortex®-M7 processor. The course includes an introduction to the Arm product range and supporting IP, the processor core, programmers' model, instruction set and debug architecture. It includes a number of worked examples and hands-on CMSIS compliant exercises to reinforce the training material.

Who should attend?

Software engineers writing application and system software for platforms using the Arm Cortex-M7 processor core.

Pre-requisites

Some knowledge of embedded systems
Basic awareness of Arm is useful but not essential
Knowledge of programming in C
Experience of assembler programming is not required but would be beneficial

Training materials

This class uses training materials developed by Arm.
