  • [SOLVED] Using the cortex M0+ Micro Trace Buffer with j-link

    Hello,

    Has anyone actually managed to correctly set up and read trace information from the M0+ MTB using j-link pro/ultra+ etc.? Keil MDK supports it with Ulink and IAR supports it with I-Jet but I am at a loss when it comes to using j-link. I seem to have tried everything without success. Is it the responsibility of the IDE to support this or is it down to the j-link itself? does anyone have a definitive answer and is this forum the correct place to get answers for these questions or should I direct them to Segger support instead? Thanks in anticipation.

    Kind regards.

  • Hi,

    This is something the IDE needs to support.
    We already got some preliminary implementation from ARM/Keil for MDK and it looks good so far.
    It is currently fine-tuned and will be released in the not to distant future (sorry, did not get any release date from ARM yet).


    Best regards
    Alex

  • Hello Alex,
    Thanks for the update. By the way I spoke to IAR yesterday and this is what they said;
    IAR Quote: "According to our development team, MTB is not supported when using J-Link.
    That support is on our TODO-list. Unfortunately, we have no information on
    any planned release date for that feature.

    An I-jet and/or a CMSIS-DAP debug probe are the only options available for MTB at the moment.
    "
    So this answers my question regarding IAR EWARM compatibility. From what you say sounds like Keil are more on the ball with this and could provide a solution sooner rather than later.
    Kind regards.
