This article describes how to get started with trace on the ST STM32L4S 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 STM32L4S MCU implements tracing via pins, so a J-Trace can be used for tracing.

Sample project

The STM32L4S MCU is comparable to the STM32L4R so the following example project can be used as reference:

Make sure to set the correct device in your Ozone project.
