Hi everyone,

I try to connect to my NUCLEO board (NUCLEO-L476RG) via STM32CubeProgrammer but I receive the following error message:

I reinstalled the STM32CubeProgrammer but nothing changed. I used to write my program to the MCU flash several times using Copy/Paste .bin file directly to the following storage before:

but I am not enable to program the MCU via STM32CubeProgrammer. Even I am not able to use Copy/Paste to program the MCU anymore.

This is my NUCLEO development board: (NUCLEO-L476RG)

Does the correct voltage show up?

Try holding BOOT0 during reset, then connecting.

If you remove connections to other things, does it work?

Thanks TDK!

I removed all connections and it works!

It seems it was something wrong in my connections.

Thanks again
