How to Enable ETM Trace for i.MXRT10xx Series

Guide for enabling Embedded Trace Macrocell (ETM) high-speed trace functionality on i.MXRT10xx series MCUs using TRACE32 debuggers and IAR Embedded Workbench.

View application note

Overview

This application note provides technical instructions for enabling ETM (Embedded Trace Macrocell) high-speed trace on NXP i.MXRT10xx microcontrollers, including the i.MXRT1010, i.MXRT1020, and i.MXRT1050. It details hardware modifications for validation boards, including specific resistor soldering requirements for JTAG and trace signal lines. The document explains how to configure Lauterbach TRACE32 software, generate compatible .elf files using IAR, and create .cmm scripts to initialize PinMux settings, clocks, and TPIU ports. Additionally, it covers advanced debugging features such as signal integrity analysis using Trace.ShowFocus and program execution tracking with timing diagrams.

Use Cases

  • High-speed real-time software debugging
  • Complex system troubleshooting
  • Code profiling and performance analysis
  • Trace port signal integrity verification
