6.4.9.2 SWV Global Trace View
Debug->Advanced commands...->SWV Global Trace View opens the SWV Global Trace View:
This view is global for all ITM channels and DWT features. It shows all the events received on the
SWV, one event by line, with the following information:
• Index: incremental event number,
• Packet: packet data as it was received, with no treatment,
• Time: time stamp of the event,
• Event: type of event with channel source number,
• Value: value sent by the event (hex value for ITM Port 1, and exception number in this
example),
• Delayed: indicates that the time is not accurate, the SWV module has not been able to set a
time to all the events that occurred (the Time Stamp event has lower priority than other events).
Available commands:
• Auto refresh: uncheck this option to temporarily navigate into the view.
• Auto resize: push this button to resize all the columns of the list, and to display all the data.
• Clear view: allows to clear the view, without stop the trace.
• Suspend Trace / Restart Trace: stops the trace, or reinitializes the trace.
• Start trace: start the trace after a suspend command.
Notes:
- Time is relative to the beginning of the trace, if Time Stamp has been validated in the DWT
configuration dialog box. In other cases, the time is absolute PC time.
- When you click on Start Trace, after having stopped the trace, trace acquisition is restarted, the
new trace events are appended at the end of the previous trace.
– When you click on Restart Trace after having stopped the trace, the trace is reinitialized (views
and buffers are cleared) and the previous trace is lost.
