Nucleo L432KCU6 upload

I cannot upload code to the Nucleo L432KCU6, if I am not pressing the RESET switch !!!
Not pressing the RESET switch I got this error:

Configuring upload protocol…

What am I doing wrong ?
Thanks in advance.



Disabled these lines in my platformio.ini:

build_flags =
;monitor_dtr = 1

And is now working too on the USB connector :+1:
