Tracing on Infineon XMC4400 series MCUs
This article describes how to get started with trace on the Infineon XMC4400 series. 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 Infineon XMC4400 series implements tracing via pins only, so a J-Trace is needed to perform tracing on these devices.
In order to use trace on the Infineon XMC4400 series 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
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 XMC4400_CPU_44A-V2 (Hexagon Board). This particular board did not support Trace out of the box as the Tracepins were not connected to the Pinheader, so additional soldering work was required. The sample project comes with a pre-configured project file for Ozone that runs out-of-the box on any XMC4400 with a 12 MHz oscillator that has the Tracepins connected. Should you use another oscillator change the PLL setup accordingly. In order to rebuild the sample project, SEGGER Embedded Studio can be used.
