FreeRTOS debug awareness

  • Hello, I am using NXP KDS3.2.0 environment with PEMicro Multilink FX debug probe. My new project uses FreeRTOS 9.0.0 and I am wodering if your GDB Server might provide some thread awareness under this RTOS?
    When I asked at NXP forum they recommended competitor's product:


  • Ludek,

    We are currently working on several new features for KDS. One of these is FreeRTOS kernel awareness. We expect it to be available this summer.



    • Hello Kevin,

      very glad to hear that. I am looking forward to use your tools. I hope my current Multilink FX would be sufficient for that job.



    • Do you have an update on when PE Micro might get thread awareness for FreeRTOS in KDS?

  • David,

    I spoke to our engineering team and we are pretty close to release of the FreeRTOS support. It was put on hold a bit to release our macOS support. We have a release date of November 30, but it will likely happen before then.



    • Thank you. That is great news.

    • Is their a new release date for this support?

      • Dave,

        We are still working on the release. There are quite a few FreeRTOS variants and build options we are still checking. Are you interested in working with a beta version? I would probably just need to know the version you are working with and a few build conditionals so we can make sure that we have tested your usage case. Otherwise, we will launch by the end of the year. I saw a demonstration of the FreeRTOS debug and it was working well.


        • I would be interested. We are using FreeRTOS V9.0.0 port for Cortex M0 with the GCC compiler from We have not made any modification to it.

          What other information do you need?

          • David,

            I will connect with you via email.


  • Hi David, 

    Our latest GDB server plugin does in fact support FreeRTOS thread awareness.

    Please go to Help -> Install New Software -> Point to our update site at to install the latest P&E plugin.

    Best Regards,

    • Hi Zahar,

      We're using S32DS with FreeRTOS on a MPC5748G. Is there a reason why Task aware debugging does not work in this environment? I am able to see the FreeRTOS tasks, but GDB does not show the tasks as threads.
      I already tried updating.

      Best regards,
      Ruud Siebierski
