    • Cannot connect to STM32 Nucleo board

    Posted by dnbharrin on 2016-10-25 07:39
    Very frustrated in trying to connect to the STM32 board via the USB port on the computer. I have tried two entirely different computers and neither will show the STM USB port for the board. I run STM32 ST-LINK Utility v4.0.0 setup and it installs just fine with no errors but no STM USB port shows up in Device Manager. What is the problem???

    Hi, Yes, as requested by Brano, please may you provide more details?
    Another proposal : some USB 3.0 Controllers (such as NEC/Renesas) have a bug that prevents access to USB devices.
    The symptom is : issues to download the binary to the board.
    You may upgrade to the latest version of the controller to fix this issue.
    It can be downloaded from :

    Still cannot connect! I obtained a second board after being told that the first board was bad. However, the second board won't connect either!!!!
    THis is a STM32L476 Nucleo 64 development board. I am connecting to a Dell Inspiron 15 laptop running Windows 7 Professional. I tried to update the USB drivers but they are all upto date. I can't understand why I am the only one having this problem. Every thing on my computer is standard stuff.

    Finally success! It turned out to be a bad cable! Always check the cable by swapping out. Thanks for all the replys.

    I've been through all the documentation and I'm getting very frustrated with this eval kit - it really shouldn't be this difficult! 😧

    Installed latest USB drivers, however the device is still not showing up under device manager->USB devices and obviously ST-Link says "no St-Link detected". I have made sure I followed the power supply sequence for USB-enumeration to succeed. Also tried several different USB cables & USB ports.

    Running Win 10.

    FWIW I have a STM32F469NIH6 DISCO kit that works with ST-link and the drivers mentioned above.

    Any help would be much appreciated.
