SDK tool cannot connect

I’m using Jetson Xavier and I tried to install Jetpack using SDK. The OS is up and running on the Xavier, but I can’t proceed to the next step. I need to put the user name and password of the Xavier, which was definitely right, but SDK keeps saying that it can’t connect. Help please?

Hi bryanjung21,

Please connect HDMI to you Xavier board.
After finished flash, you need initial setup process and select username/password (need connect monitor to setup), then the Jetson system boots to the Linux desktop, you can install SDK components again.
