Tracing on ST STM32F767

This article describes how to get started with trace on the ST STM32F767 MCU. This article assumes that there is already a basic knowledge about trace in general (what is trace, what different implementations of trace are there, etc.). If this is not the case, we recommend to read Trace chapter in the J-Link User Manual (UM08001). The ST STM32F767 MCU implements tracing via pins, so a J-Trace can be used for tracing.

Minimum requirements

In order to use trace on the ST STM32F767 devices, the following minimum requirements have to be met:

  • J-Link software version V6.14a or later
  • Ozone V2.22o or later (if streaming trace and / or the sample project from below shall be used)
  • J-Trace PRO for Cortex-M HW version V1.0 or later

Sample project

Streaming trace

The following sample project is designed to be used with J-Trace PRO and Ozone to demonstrate streaming trace (1-bit trace is used in the sample project). The project has been tested with the minimum requirements mentioned above and a STM32F767_Nucleo-144 Evalboard. The sample project comes with a pre-configured project file for Ozone that runs out-of-the box. In order to rebuild the sample project, SEGGER Embedded Studio can be used.

Note: As the evaluation board does not have trace pins connected by default, modifications had to be applied to the board, to make trace available. This is however not recommended by us and trace should be supported by your hardware per default.
