Aftr flashing Jetpack 5.0.1, there is no display and I cannot ssh into it.

Even the following command fails: sudo ./flash.sh jetson-agx-orin-devkit mmcblk0p1
with the same error as before “Reading board information failed”.
Should I install Jetpack 5.0.1 DP again and setup using serial console?
I cannot use picocom to set it up using the terminal either. There is no option. It says: 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.
It mounts a partition called “L4T-README” though. Not sure if that helps.
I don’t have any “patch” to fix your display issue. None of my patch or comment here is for your display.
That sounds a unknown issue to me. And I think we could check that after we fix your console issue.
If you are talking about /dev/ttyACM0 never showed up on your host when you flash with sdkamanger jp5.0.2, then please describe the detail steps how you apply the patch and flash your board…
I am able to see the output at /dev/ttyACM0 when I flash 5.0.2. But then it says 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.
For flashing 5.0.2, I dd:
“Manual setup for Jetson Orin 32GB” with Runtime setup and only installed the L4T BSP only without SDK components.
I have Jetpack 5.0.1 DP. I have access to the serial console.

I am able to reboot and then still have access to /dev/ttyACM0.
Should I disconnect the microUSB debug cable now and try to boot it?
or should I update/install any packages or see any IP addresses before I shut it down and lose access to /dev/ttyACM0?
(I am asking because earlier, once I shut it down, it never came back again)
