Project overview

• Study and document the STM32 Debug and Trace infrastructure, with emphasis on the new Debug and Trace unit.
• Produce an application note that explains PMU (Performance Monitoring Unit) and ETR (Embedded Trace Router), their principles of operation and practical usage.

Work to be done / Objectives

• Define and explain PMU and ETR, including working principles and architecture-level considerations for Arm Cortex-M / STM32 CPUs.
• Identify and document concrete use cases and decision guidelines on when to use PMU vs ETR for performance analysis, debugging and trace.

Technical tasks & deliverables

• Develop step-by-step practical examples demonstrating how to use PMU and ETR to debug and trace applications on STM32, providing instructions for both IAR and Keil IDEs.
• Deliver a complete application note (document) containing theory, configuration steps, example projects, measured results and recommended workflows for engineers.

Required skills & environment

• Strong knowledge of Embedded C and firmware development for STM32 (Arm Cortex-M CPU).
• Experience with debugging and trace tools; familiarity with IAR Embedded Workbench and Keil MDK is required.
• Familiarity with STM32 architecture, performance counters (PMU) and trace streaming/router concepts (ETR) is a plus.

Keywords & context

• Embedded C, IAR, KEIL, STM32 architecture, Arm Cortex-M CPU, STM32 debugging.
• The work targets engineers and firmware developers who need reproducible, IDE-specific procedures to enable PMU/ETR-based debugging and performance analysis.
