Jetson TX2 custom board HDMI1 to DP1 mapping problem

Hi all!
We’ve got a custom board for Jetson TX2 module with HDMI mapping error. The correct mapping is as follows:
HDMI1_TXC → Jetson DP1_TX3
HDMI_TX0 → Jetson DP1_TX2
HDMI_TX1 → Jetson DP1_TX1
HDMI_TX2 → Jetson DP1_TX0

But we are route PCB with mapping as follows:
HDMI1_TXC → Jetson DP1_TX3
HDMI_TX0 → Jetson DP1_TX0
HDMI_TX1 → Jetson DP1_TX1
HDMI_TX2 → Jetson DP1_TX2

Can you please tell me if there is a software solution to this problem? Maybe a change in the kernel configuration or somewhere else? Or can this problem be solved only by physically changing the board routing?

Search the keyword “nvidia,xbar-ctrl” in your dtsi and swap the place of 0 and 2.
