Searching

With the Find tool you can search for particular events in a scope of the selected area.

1. Select the area you are interested in and open Find dialog (CTRL+F).

2. Enter the search criteria, which can be any of the statistics available in the profiler (net, gross, call, inactive time), units s, ms, us, ns are supported.

3. When a match is found, the timeline markers will be set around the event. If Snap area on find is enabled, the result will be snapped into view.

 

 

 

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 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.
