I’m trying to do a headless installation of a Jetson AGX Xavier DevKit but I’m confused by the instructions. The DevKit User Guide (12/17/2019) says “If no display is attached to the developer kit during this first boot, the initial configuration is “headless.” That is, you must communicate with the developer kit through a serial application on the host computer (e.g., puTTY) connected via a host serial port and the developer kit’s Micro-USB port.”
So I connected both the front USB-C connector and the Micro-USB port to my host computer. When I connect the Micro-USB ports, I see four ttyUSB* ports showing up in /dev. I use the screen command on all four of them. After the SDK Manager finished flashing the device, I can see startup debug messages on /dev/ttyUSB3. The last message says to complete the initial configuration on /dev/ttyACM*. However, I don’t see ttyACM ports showing up in /dev. What am I doing wrong?
For first boot up and setup initial configuration on /dev/ttyACM* is working on host ubuntu 18.04.
Please check you are connect micro-USB cable (J501) and type-C port (J512) on Xavier to your host ubuntu.
Yes @carolyuu, as I mentioned in my original post, I have both the front USB-C connector and the Micro-USB port connected to my host computer. The /dev/ttyACM* don’t show up on the host, only four /dev/ttyUSB*.
@DaneLLL, I tried with a different cable and a different host computer as well. Same result. I only see /dev/ttyUSB* but not /dev/ttyACM* is there any other ways to troubleshoot what’s wrong?
