During flashing of the Xavier NX on the CTI Quark carrier board I see the following error:
[ 5.7903 ] Sending bootloader and pre-requisite binaries

Error: None of the bootloaders are running on device. Check the UART log.
Failed flashing t186ref.

I can confirm the board is in recovery mode using lsusb but it appears to go into a reboot loop. I have setup the install using
https://connecttech.com/resource-center/kdb373/
and
https://connecttech.com/resource-center/kdb377-booting-off-external-media-cti-jetson-carriers/

and my flash command is:
sudo ./flash.sh cti/Xavier-NX/quark external

Hi nlynch,

Please contact with CTI support: Support - Connect Tech Inc.

Update - after contacting connect tech support, I tried replacing the power supply and that appears to have resolved the issue

Had same issue here, helped to combine all three Power and Ground wires of the connector, and then juice the board at 5.25v rather than 5v flat.
