Nucleo LD1 Light dims after sometime and St-link is not recognized by the laptop

I have an STM32F401 nucleo board and it used to work fine but now after a minute of connecting it with usb, the LD1 suddenly dims to very low light like pin on float. Before that it works fine, I can program it, debug it.

Hi @Lakshay ,

Try using STM32CubeProgrammer to check if you can connect to the board. Probably you need ST-Link firmware upgrade.
