I’m using only Jetson nano module without carrier board and designing the HDMI interface manually with other PCB.

Please follow the nano Design Guide to make custom design.

In addition, you can find all docs needed for design in DLC.

can i get SW Driver for Xavier NX HDMI interface? Could you please share?

Is this issue for Nano or for Nx?

Now planning to with NX. So, need it for NX.

Not quite sure about what “software code” you want to ask. The overall software stack is long and not every code is public release.

The kernel source code is released as tarball in L4T archive.

How to make HDMI CEC connection? The HDMI_CEC (pin 94) in Xavier NX is 1.8V open drain but the reference schematic level shifter used is 3.3V itself in developer kit. What is the voltage level of CEC pin coming from connector and why we need level shifter?
