ML Universal FX not working anymore

Staff: Johnny N.

  • I have a Multilink Universal FX which I've been using for over a year.  I was having some (still unresolved) issues programming a Kinetis KV58 device.  I uninstalled and reinstalled the latest drivers, and now it's not working at all in any USB ports.  It still works on an old Win 7 machine (which I can't use for other reasons).  Can someone please help me get this working.  I've tried uninstalling, rebooting, and then reinstalling to no avail.  I'm completely stalled.

    The Kinetis Recovery Utility does not see the ML FX. It looks OK in Device Manager, though.



  • I have the same issue.  I likewise am working with a KV58 device.  I uninstalled and re-installed and now I have the same issue as you.

  • I did finally just figure it out - had to update my drivers with the latest drivers available with MCUXpresso.

    Since you are also using a KV58 - did you encounter any issues with the NMI being active interfering with debugging?

  • My memory is a bit fuzzy, but yes, I remember some issue with NMI needing to be disabled to get things to behave properly.
