Trace Exporter for On Time RTOS-32

The purpose of the Trace Exporter tool is to export the trace data from the On Time RTOS-32 Kernel Tracer to the Tracealyzer application. The Trace Exporter creates an XML file which can be opened in Tracealyzer for On Time RTOS-32. The Trace Exporter is delivered in C source code and needs to be included in your embedded application.

Note that Percepio’s Trace Exporter is only a data converter, not a monitoring solution/recorder. It only runs momentarily, when the export function is explicitly called. The actual monitoring is done by the standard Kernel Tracer of On Time RTOS-32, provided by On Time Systems. The resulting XML file must be manually transferred from the target system to the host PC.

Requirements:

• The required On Time RTOS-32 components are RTTarget-32 and RTKernel-32.
• The Debug-version kernel of RTOS-32, where the Kernel Tracer is active.
• Make sure that RF_TRACE_TIME_NS or RF_TRACE_TIME_US is set in RTKConfig.Flags.

Usage:

1) Add “trcExport.c” in your build project.

2) Include the header file “trcExport.h” in your source code.

3) When you like to generate the trace file:

3 a) Stop the Kernel Tracer by calling RTKStopTracing, an API function of the On Time RTOS-32 Kernel Tracer.

3 b) Call vTracealyzerExport(“filename.xml”), which is found in trcExport.c.
