Hello all,

I am programming on the NUCLEO-C031C6 and have some errors debugging the project. I have connected the board with micro-usb as it must. However i get following error message:

    Hello @dramanovic 

    Make sure to update the ST-Link Firmware and ST-Link server software.

    Make sure to use the last release of CubeIDE.

    Check the USB cable and connectors.

      Thank you for your help!
      The error has not been resolved, however i do not know if the st-link server is started since i ran the .bat file from the link you provided. However i should only give administrator rights and did not receive any feedback if successfully installed.
      In my FAIL.txt file from the board itself, it states:The interface firmware FAILED to reset/halt the target MCU.

      After disconnecting and reconnecting the Board, the LD1 is constantly red. However after trying to run a project and when the error occurs, it turns constantly green.
      Is it possible, that the connecting micro-usb cable is the issue or is there another way to possible fix it?

      Thanks,

      David
