LEDs of Nucleo-STM32G070 does not light on at power on

[Chao]

Hi All

Just bought a Nucleo-STM32G070 board and I am new to STM32 MCUs, I tried to power the board with a micro USB cable that I used to charge my mouse after I have installed the USB driver (stsw-link009), but the LEDs do not light on as shown in the introduction video. I did not remove or add any jumpers, did not make any change on the board.

Anybody knows where the problem is?

Are you sure that's a full USB cable - not just a charging cable?

Have you tried a different cable - one that you know gives a full data connection?

Hi Andrew,

It is just a charging cable I think, as it came with my mouse. Do you mean I need a FULL usb cable? I will try one.

thanks

Well, the LEDs indicate comms activity with the ST-Link - and there won't be any comms if it's just a charging cable.

bought a usb cable and the lights are on (LD1 stays red, LD3 stays green, and LD4 blinking green and off)

thank you Andrew.
