  • Hello,

    Thank you for your inquiry.
    Such an issue is not known to us.
    Are you using custom hardware or an eval board?
    Does SWO output work with the non CL version of SWOViewer?

    Best regards,
    Nino

  • Hello,

    The board is NXP-lpcxpresso54608.

    Ok great, we have the same board in house. Could you provide us with an example application to program to it for reproduction?
    A hex or bin file would be sufficient.

    Best regards,
    Nino

  • Hello,

    Attachment is an application will print "hello_world" in SWOViewer when you press sw2 button.

    This application does not trigger any SWO output.
    Make sure that you don't reconfigure any SWO related registers that are not device specific. Everything else is will be set by J-Link correctly.
    If you change Coresight register values afterwards with your application SWO will not work.
    All device specific inits can be passed through a J-Link scriptfile.
    More information can be found in the J-Link user manual.

    Such a Script File will be shipped with future J-Link software versions so LPC54608 runs out-of-the-box.
    As you are working for NXP make sure that for future requests like this to get in touch with us per e-mail. This is not a support forum so there is no guarantee that you will receive an answer from us here.

    More information about this can be found in the forum rules or in my signature.

    Seems the JlinkSWOViewerCL.exe support set swo freq automatically only, -swofreq not work, please confirm if this behavior is expected or not, thanks!

    -swofreq is supported in JLINKSWOViewerCL as well. How does your command line look like?

    EDIT: LPC54608J512 native SWO support has been fixed with J-Link software V6.32d.
