Working on Ubuntu Desktop 18.04.2 with a Jetson-Xavier that has stopped working.
The UART Debug channel throws

Failed flashing t186ref.
I get the same error when trying to flash Jetpack 4.2
I have run through the forums but there is no obvious place to find the meaning of this return value and the debug error is equally unhelpful.
