what mean ??
tegradc 15220000.nvdisplay: No free extcon HDMI slot for DC 2**
tegradc 15220000.nvdisplay: dc_hdmi_out_enable: couldn’t get regu lator avdd_hdmi

In addition, why does this message appear! Unable to enter the settings
“Please complete system configuration setup on desktop to proceed”

2

Connect the flash port to your host and open /dev/ttyACM0 to configure the system first.

3

flash port ???

4

The usb port that you used to flash the board.

If you don’t even know what does this mean, maybe you should buy a AGX devkit and try this thing first.

“Please complete system configuration setup on desktop to proceed” is just the first user configuration to do when you install fresh jetpack.

XAV
After updating the system from DOWNLOAD PORT before
Connect to DEBUG PORT to directly set the system,
This message will not appear
“Please complete system configuration setup on desktop to proceed”

Now the customized board also has the same design
So I don’t know why I can’t use the debug port to set

6

You can only use the flash port to set the system.

Do you have any language problem to understand this sentence “flash port is the port that you use to flash the OS”?

Open /dev/ttyACM0 on your host side with console tool. Is it ok to understand this?

Back to the HDMI problem
How to preset three HDMIs to be clone mode, not extended mode in dts setting?

It cannot be configure in DT. Need to set with ubuntu GUI.
