RTOS trace tools

 

Introduction

Tracealyzer from Percepio is a powerful runtime analysis tool for FreeRTOS applications. It captures valuable dynamic behaviour information for offline display in more than 25 graphically interconnected views. The captured information is invaluable when you want to troubleshoot, optimise, or simply analyse the performance of your FreeRTOS based product.

Tracealyzer can be used side-by-side with a traditional debugger, and complements your debugger by visualizing the real-time execution of tasks and ISRs, including FreeRTOS calls and your own “User Events”.

 

Integration

Tracealyzer has two components – a PC application and a trace recording library. The trace recording library is provided as C source code for easy inclusion in your FreeRTOS project build. The library itself uses the standard FreeRTOS trace macros.

Tracealyzer can obtains traces through your existing debugger interface or any other communication interfaces you might have available, such as TCP/IP or USB, so does not depend on additional hardware. Tracealyzer supports continuous streaming and also in-memory “snapshot trace” that allows for capturing rare errors in deployed hardware that are not easily reproducible in a bench test.
