Host machine: ubuntu 18.04
sdk manager version 220.127.116.1138
I have a agx xavier board which was running jetpack 4.3 without a problem. I put it into forced usb recovery mode and tried to update the jetpack to 4.4 using sdk manager. However, at the step where the sdk manager asks for you to complete system setup using the HDMI monitor to enter the username and password, there was NOTHING on the HDMI monitor. Obviously, I couldn’t continue, so I clicked ‘skip’ … expecting the board to remain at jetpack 4.3. However from that moment on, the HDMI monitor stopped detecting a signal from my board.
I am able to see output from the debug port, and I am able to manually flash it by cd to ~/nvidia/nvidia_sdk/JetPack_4.3_Linux_JETSON_AGX_XAVIER/Linux_for_Tegra using the command:
sudo ./flash.sh jetson-xavier mmcblk0p1 | tee flash_2020-09-05.out
It appears to flash successfully because my log flash_2020-09-05.out shows the message:

Reset the board to boot from internal eMMC.
However, when I reset the board, I see this message on the minicom

ÿâWARNING: pll_d3 has no dyn ramp
How can I complete system configuration setup on desktop… when the monitor doesn’t detect hdmi signals from the board? I have tested the monitor and the cable with other sources, and the monitor displays images from other sources without a problem.
Any ideas on what could be the problem? Or any ideas on how to recovery to factory settings???
