Hi 1025784161,

After finish image flash, are you complete first init process setup?
Please connect HDMI monitor and check it boot to Desktop GUI.
Then connect flash cable (J512) from Xavier to host machine, using “ifconfig” command to check IP address.
Or you can using eth0 IP address to instead of device IP address (192.168.55.1) to install sdk components.
