Staff: Steve M.

  • Hi, I have a STM32L476VG discovery board and I want to program it with jtag communication and PE micro multilink universal programmer and IAR IDE.

    I have installed a firmware of ARM in PE programmer and I have connected NJRST, JTDI, JTMS, JTCK, JTDO, NRST of programmer to the board then I Chose PE as debugging driver in IAR IDE.
    but can not communicate with MCU.
    I have checked the wires connectivity but problem is not solved.


    • Hi Mohammad,

      Thank you for reaching out to us on this issue. I would suggest setting up a Support Request through our website so we can acquire screenshots of your connection settings as well as screenshots of your hardware setup. That way we can more effectively replicate and help debug your issue.
