Tracing on NXP Kinetis MK60N512

This article describes how to get started with trace on the NXP Kinetis MK60N512 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 NXP Kinetis MK60N512 MCU implements tracing via pins or via on-chip trace buffer (ETB), so a J-Trace as well as the ETB can be used for tracing.

Minimum requirements

In order to use trace on the NXP Kinetis MK60N512 MCU devices, the following minimum requirements have to be met:

  • J-Link software version V6.18c or later
  • Ozone V2.46a 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

To rebuild the project our IDE Embedded Studio can be used. The recommended version to rebuild the projects is V6.30. But the examples are all prebuild and work out-of-the box with Ozone, so rebuilding is not necessary.

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 TWR-K60N512(SCH-26548 Rev.A) Towerboard. 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: The example is shipped with a compiled .JLinkScriptfile, should you need the original source, please get in touch with SEGGER directly via our support system: https://www.segger.com/ticket/.

To create your own .JLinkScriptfile you can use the following guide as reference: How_to_configure_JLinkScript_files_to_enable_tracing

ETB trace

ETB tracing is available and can be used with J-Link. Simply set ETB as the trace source in your debugger.

Note: The ETB does not support streaming trace.
