  • [SOLVED] Ozone: SWO issues

    Hello Nino,

    I noticed another problem:
    The activation of SWO fails at startup. I need to configure it manually. This is the Output I get:

    >> Disabled output of control characters
    >> SWO active
    >> failed to activate SWO data capture: SWO trace cannot be started: invalid core frequency
    >> SWO inactive

    Is it possible to activate SWO when breaking at main() ?

    Kind regards
    Andreas
  • Hello Andreas,

    Thank you for your inquiry.
    Such an issue is not known to us.
    How are you activating SWO in Ozone? Did you enable it under Tools->Trace Settings->SWO?
    Are CPU and SWO speed selected as auto?
    How are you using SWO in your application? Keep in mind that Ozone currently only supports printf messages over SWO but no trace.
    Trace over SWO will be added at a later point.

    Best regards,
    Nino

  • Hello Nino,

    when I start Ozone, I normally load one of my pre-configured "jdebug" files. SWO is activated in these files. But when start Debugging, it connects to the Target and breaks at "main". Then I see that SWO cannot start.
    I've selected anything as "auto" and I use SWO only for printf now.

    Kind regards
    Andreas
  • Hello,

    Which target device are you looking to use SWO on?
    Some require extra init steps. More device specific special cases can be found on our wiki.segger.com website.
