Contents
This article describes how to get started with trace on the NXP LPC845 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 LPC845 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 LPC845 MCU devices, the following minimum requirements have to be met:
- J-Link software version V6.46 or later
- Ozone V2.62 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 LPCXpresso845MAX 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 streaming trace.
Streaming trace
Streaming trace is not supported on this particular target device.
