    • RTT slow not usable anymore

      We have been using RTT for many years now and since a few months the logging output became so slow that it's unusable.

      I've seen post here with the workaround using a older version of the driver.

      What is the timeline in fixing this issue?

      We already decided not to use RTT with any future projects anymore.
      But we still have to rely on it for the legacy hardware.
    • Hello,

      Thank you for your inquiry.
      Such an issue is not known to us with the latest version.
      Which J-Link software version are you currently using? Does the behaviour improve when using the latest one?

      What tool are you using for logging? Your own, or one of the J-Link tools?

      The old reported issues in the forum have all been fixed already.

      May we ask what your alternative solution is?

      Best regards,

      I have been using the latest v6.42d and there is still a lot of lag in the RTT viewer compared to say v6.32i

      Actually I ran another test, 6.32i RTT Viewer is about 1000% faster than anything released after that - 6.42d and 6.43a are both hopelessly slow. I assume you are somehow buffering the data before writing it out to the display, whatever you used to do was perfectly adequete. I end up going back and using it even though the DPI support is kinda poor in that version.
