LED turning red

[Lello1]

What do you when your LD1 turns red everytime you plug-in a cable? The name of my board is nucleo-g071rb, I'm using cubeIDE. I am trying to do an STLink upgrade, but it says I'm not connected and should check my cable. LD3 and LD4 turn green, but LD1 turns red.

Hello @Lello1 

No need for a code. Everytime you plug-in a cable in an stm32 nucleo board, the green LED LD3 lights up, LD1 blinks. So you can now if the cable is plugged in or not.

Best regards.
