Context Selection

If an operating system is running on the embedded target, analyzer can be configured to record task switches, so that the program flow can be correctly reconstructed. In such case click the Context button ProfilerAnalysis-Timeline-ContextButton and select the context you wish to analyze. Note that Profiler creates one additional context for each core (called unknown_<coreID>), to which it attributes all events that happen before the OS task is first signaled.

 

A core can be selected via Current task drop-down in the Profiler Timeline window:

Neutral - All cores are merged and displayed in one timeline.

PCS: CPU Name - Context for a specific core.

 

 

Configuration options

Refer to Profiler Configuration.

 

 

Exporting the trace data

Profiler Export dialog allows you to export the profiled data in various formats: CSV, BTF, MDF, XML, Text1, HTML. For more information, refer to Profiler Export.
