Just attempted to updated my AGX developer kit from Jetpack 4.4.x to 4.5. via the SDK manager under Ubuntu 18.04. Everything went well with flashing the OS image, until it was time to run oem-config. I am running headless and unable to put a display on the unit; in the past I was able to run config from the command line on the virtual serial port /dev/ttyACM0
In this case there is no content on /dev/ttyACM0. Connecting to the serial port I see a good set of boot messages, ending in :
[ 11.130138] Please complete system configuration setup on the serial port provided by Jetson's USB device mode connection. e.g. /dev/ttyACMx where x can 0, 1, 2 etc.
Any chance oem-config / tty is not properly being setup on /dev/ttyACMx in this version of Jetpack?
After reboot, I get the virtual disk (L4T-README) and the network connection. I can ping, and can connect to /dev/ttyACM0, but no data on that virtual serial port.
