      We are designing a new card to be debugged using a J-Trace Pro (Cortex-M) and I have a question about J-Tag connectors:

      Are there any reasons to consider including connectors for both the large grey "Target" cable and the small black "Target+Trace" cable?
      Or does the "Target+Trace" cable provide 100% functionality and thruput?

      Hello Russ,

      Thank you for your inquiry.

      Only use the Target+Trace interface if you are looking to trace. The bigger grey cable interface is only meant for backwards compatibility and only debugging.
      Connecting both will result in degradation of Trace signal quality.
      We are currently updating our manual to reflect this better.

      Best regards,
      Nino
