@AGVV_TII we now have Orin Nano Developer Kit and you can use Orin NX with Orin Nano developer kit and it is fully supported in JetPack 5.1.1 and from SDK Manager as well.
We would not recommend using Orin NX on Xavier NX carrier board because it is not fully pin compatible, so only I/O’s that overlap will work on Xavier NX carrier board.
Hope this explains.
@AGVV_TII I’m not sure if you resolved this, but you can see where the functionality diverges by using Nvidia’s Migration Guide document. (Search “Migration Application Note” in Jetson Download Center.)
I’m curious about carrier board compatibility this as well, @suhash
I’ve been following along Nvidia’s Migration Guide document for Orin NX and Xavier NX. I’m using the pinmux spreadsheet with the goal of using an Orin NX on Xavier NX carrier board. For the I/O that overlap, I imagine nothing needs to be changed in the pinmux. For the I/O that don’t overlap, are we to change the ‘customer usage’ entry of all those pins to the ‘unused’ option in the pinmux dropdown?
