The usb port that you used to flash the board. If you don’t even know what does this mean, maybe you should buy a AGX devkit and try this thing first. “Please complete system configuration setup on desktop to proceed” is just the first user configuration to do when you install fresh jetpack. ---

You can only use the flash port to set the system. Do you have any language problem to understand this sentence “flash port is the port that you use to flash the OS”? Open /dev/ttyACM0 on your host side with console tool. Is it ok to understand this? ---
