Events view

Use the Events view to view the output generated by the System Trace Macrocell (STM) and Instruction Trace Macrocell (ITM) events.

Data is captured from your application when it runs. However, no data appears in the Events view until you stop the application.

To stop the target, either click the Interrupt icon in the Debug Control view, or use the stop command in the Commands view. When your application stops, any captured logging information is automatically appended to the open views.

Note

  • Use the Event Viewer Settings dialog to select a Trace Source as well as to set up Ports (if ITM is the trace source) or Masters (if STM is the trace source) to display in the view.
  • To view the Live Decode tab and streaming trace data, you must enable the Show live decode console option in the Event Viewer Settings dialog.

Toolbar and context menu options

The following options are available from the toolbar or context menu:

Linked: context

Links this view to the selected connection in the Debug Control view. This is the default. Alternatively you can link the view to a different connection. If the connection you want is not shown in the drop-down list, you might have to select it first in the Debug Control view.

Clear Trace

Clears the debug hardware device buffer and all trace sources. The views might retain data, but after clearing trace, refreshing the views clears them as well.

Start of page

Displays events from the beginning of the trace buffer.

Page back

Moves one page back in the trace buffer.

Page forward

Moves one page forward in the trace buffer.

End of page

Displays events from the end of the trace buffer.

View Menu

The following View Menu options are available:

New Events View

Displays a new instance of the Events view.

Find Global Timestamp…

Displays the Search by Timestamp dialog which allows you to search through the entire trace buffer. The search results opens up the page where the timestamp is found and selects the closest timestamp.

Update View When Hidden

Enables the updating of the view when it is hidden behind other views. By default this view does not update when hidden.

Refresh

Refreshes the view.

Freeze Data

Toggles the freezing of data in the current view. This option prevents automatic updating of the view. You can still use the Refresh option to manually refresh the view.

Events Settings…

Displays the Settings dialog where you can select a trace source and set options for the selected trace source.

Open Trace Control View

Opens the Trace Control view.

DTSL Options…

Opens the DTSL Configuration Editor dialog box.

Events context menu

Advance / Go back local timestamp amount

Displays the Advance / Go back local timestamp dialog box which allows you to move forward or backward from the current record by a local timestamp amount. A negative number indicates a movement backward. The search moves forward or backward from the current record until the sum of intervening local timestamps is equal to or exceeds the specified value.

Global Timestamps

Timestamps represent the approximate time when events are generated.

Synchronize Timestamps

Synchronizes all Trace and Events views to display data around the same timestamp.

Set Timestamp Origin

Sets the selected event record as the timestamp origin.

Note

For a given connection, the timestamp origin is global for all Trace and Events views.
Clear Timestamp Origin

Clears the timestamp origin.

Timestamp Format: Numeric

Sets the timestamp in numeric format. This is the raw timestamp value received from the ITM/STM protocol.

Timestamp Format: (h:m:s)

Sets the timestamp in hours:minutes:seconds format.
