      I am getting this error message, only after using breakpoints. I have swapped debuggers but no joy. This just started out of the blue. Any help will be appreciated.

    • Hello,

      Thank you for your inquiry.
      The J-Link software version you are using is a couple of months old. Could you give the latest software version a try?
      segger.com/downloads/jlink/#J-…twareAndDocumentationPack

      Does that solve the issue?

      Best regards,
      Nino

    • Hello,

      Could you provide a J-Link log of the session?

      You write that it started out of the blue. Did you change anything in your setup? Other cables, other USB input, other host PC, firewalls etc.?

      Best regards,
