This article describes how to get started with trace on the Renesas R7S721001WS (RZ/A1H) 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 Renesas R7S721001WS (RZ/A1H) MCU implements tracing via pins , so a J-Trace can be used for tracing. ETB tracing is implemented as well and can be used even with a J-Link.

Minimum requirements

In order to use pin trace on the Renesas R7S721001WS (RZ/A1H) devices, the following minimum requirements have to be met:

  • J-Link software version V6.20h or later
  • Ozone V2.52b or later (if streaming trace and / or the sample project from below shall be used)
  • J-Trace PRO for Cortex 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. The project has been tested with the minimum requirements mentioned above and a RSK2+RZA1H board. 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.
