Event ViewerThe Event Viewer displays thread, interrupt, and exception execution over time. To display the timing information it uses trace information generated by Cortex-M3, M4, M7 devices and requires a suitable debug adapter, for example ULINKpro. Prerequisites for using the Event Viewer
Open the window with Debug - OS Support - Event Viewer.
Where
Load... imports the thread- and exception-switching history previously saved in a file (*.UVTSK). Data can be analyzed off-line. Save... stores the thread- and exception-switching history in a file (*.UVTSK) for future analysis. ? opens this help. Time fields show:
Zoom buttons change the time scale:
Update Screen buttons control the screen output.
Jump to buttons synchronize the event with:
Transition buttons snap the Reference Line to the next transition point. Highlight a thread name and click:
Checkboxes
All Threads graphThe All Threads graph shows event-switching occurrences with a blue X. Blue opening brackets < (left red circle in the picture) indicate event-switching occurrences that cannot be resolved on the graphical scale. You can zoom-in at those points to view detailed event switches. The red opening bracket < (right red circle in the picture) indicates event-switching occurrences that cannot be resolved on the graphical and time scale. Zooming in at those points will not deliver details on the time scale. The events are shown as if occurred at the same time. This is due to lack of timing information. Select a smaller number for Timestamps Prescaler in Options for Target - Debug - Settings - Trace. Additional mouse and key commands
