This article describes how to get started with trace on the NXP Kinetis KE1xZ 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 KE1xZ MCU implements tracing via via on-chip trace buffer (MTB), so a J-Link can be used for tracing. Tracing over pins is not supported by this target device.

Minimum requirements

In order to use trace on the NXP Kinetis KE1xZ MCU devices, the following minimum requirements have to be met:

  • J-Link software version V6.36 or later
  • Ozone V2.60 or later (if trace and / or the sample project from below shall be used)
  • J-Link Plus V10 or higher

Sample project

MTB trace

The following sample project is designed to be used with J-Link Plus and Ozone to demonstrate MTB trace. The project has been tested with the minimum requirements mentioned above and a FRDM-KE16Z evaluation 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.

Note: The MTB does not support stream tracing.

Streaming trace

Streaming trace is not supported on this particular target device.
