Jetpack 4.4 login password


I flashed the latest Jetpack 4.4 with Etcher. Now I’m trying to connect to Jetson nano from linux using tty:

sudo screen /dev/ttyACM1 115200

and I get a login prompt:

Ubuntu 18.04.4 LTS localhost.localdomain ttyGS0

localhost login:

So, what should I do next?

I think that on very first boot you need a local keyboard, mouse and display for configuring the jetson. In this step you would define your user name and password, network…
After that it will reboot and you should be able to log in with defined username and password.
