nvidia,typec-port = ;
This one is still in your device tree, could you remove it first?
The attachments are the dts without any “nvidia,typec-port” and dmesg log.
How to config eDP?
Our DP/eDP connection is used in inter-chip case, and our hardware engineer suggest that we had better config to eDP. And our pull-down/pull-up on aux had been removed.
Can you help to config eDp?
Thanks a lot.
eDP configuration is not standard one as DP case. And we don’t have one enabled for AGX.
But I have one that was used for TX1.
You can refer to " tegra210-jetson-cv-p2597-2180-a00-auo-1080p-edp.dts" in Nano/TX1 source code.
Also, this needs to check the driver code. Directly adding device tree may not directly make it work.
If we do not pull up AUX- to 3.3V on the device side, but the device is placed very close to XAVIER, can we still use DP config?

In the log-5, there many error:
[ 1.886467] tegradc 15210000.nvdisplay: dp: aux write got error (0x10000100)
Can you help what reason may cause this error?
While the error “dp: aux write got error (0x10000100)” appears periodically, the aux wave is like the pulse in the picture.
Is the aux signal correct?
