Trace logs visible in JLinkSWOViewer but not in Ozone

Hi,

I'm using a i.MXRT1061 with SWO logging enabled. I set up JLinkSWOViewer with the appropriate frequency settings f_cpu=132MHz and f_trace=7.5MHz and I it shows the correct log output of my firmware. When setting up Ozone with the same settings nothing appears in the terminal view except for the line

- - - - - - - - - - - - - - - - - TARGET RESET - - - - - - - - - - - - - - - - -

What can be the reason? What can I else look for? Does anybody have some hints?

Thanks and regards,
Oliver

Hi oskar,
did you enable SWO capturing in Ozone's terminal window?

Hi Oskar,

In case the JLinkSWOViewer works correctly it should also work in Ozone without issues, when using the same settings.

Did you configure all required settings described in section 5.12.2 of the User Guide?
SWO is configured using the trace settings dialog. The correct settings are required for it to work.

In case the auto configuration is used: Could you please check whether the issue persists when manually setting all fields?

Should the issue not be resolved: Could you please provide more information regarding the setup? What board is being used?

Best regards,
SebastianB
