Contents
This article describes how to get started with trace on the NXP Kinetis MK21FN1M0 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 MK21FN1M0 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 MK21FN1M0 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
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-K21F120M 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: The example is shipped with a compiled .JLinkScriptfile, should you need the original source it can be requested at support@segger.com
To create your own .JLinkScriptfile you can use the following project as reference: Tracing on SEGGER_Cortex-M_Trace_Reference_Board
ETB trace
Note: The ETB does not support stream tracing.
