  • [ABANDONED] Failed to open listener port 2331

    I'm trying to use the j-LINK EDU debug probe along with a custom board built for our product.
    This board has a STM32L152RE Arm microcontroller and a JTAG pin out to be used with this wire
    I use TrueStudio IDE to build are project.

    It worked well for almost a week, I could flash and debug our board effortlessly from within the IDE itself. Until suddenly it started showing me the following error -

    I can confirm that neither the board nor the Debug probe have an issue because the both of them communicate and establish connection using the 'J-link Commander' (See attached images)

    Please can someone help solve the issue

  • Hello,

    Thank you for your inquiry.
    Such an issue is not known to us.
    According to your post it seems that you are using a J-Link EDU for commercial purposes.
    This would be a violation of the terms of use agreement.
    Do you have another J-Link probe that can be used for commercial purposes (J-Link Base or higher)? Otherwise we would have to close this inquiry down.

    Best regards,
    Nino
