Indeed, adding "console=tty0 console=ttyS1,115200" to the append line in extlinux.conf, now the serial connection works. But initial-setup, even if the answers appears in the serial interface, doesn't work: in reality there is a login screen. Here you can find a screencast to better understand: https://alciregi.fedorapeople.org/webm/rpi3serial.webm Using the hdmi monitor and the keyboard, initial setup works.

----- Original Message ----- Thanks for all the testing Alessio! With our Beta release already delayed, I think we need to document using the display to configure initial setup for the Raspberry Pi 3 (which is what most users will do) and get this fixed for final. Initial-setup over serial works on all other hardware tested.

The kernel could see the serial port anyway due to the DT, and the kernel might get the option automatically by the bootargs or console options from the firmware although I'm guessing here.
