DP port does not work. (JETSON XAVIER NX)

I implemented HDMI and DP ports by referring to the P3509-A1 circuit. The HDMI port works, but the DP port doesn’t.

It is a symptom that is not recognized by the monitor.

If the schematic and impedance matching are the same as the P3509-A1, what should I do?

Which jetpack release are in use?

Version :4.6-b197

Sounds weird. Any dmesg to share here? Please remember to plug the DP monitor before dumping log.

When the DP is connected, the monitor confirms that there is no signal.

I thought you asked for the jet pack version, so I showed it.

So where is your dmesg?

Do you know what I am asking for? Any software guy there working on Linux kernel?
