Thanks. That’s very odd. It appears that you have no dtb file under /boot/dtb. Can you confirm that you have no files there?

ls -l /boot/dtb/

I have flashed the released version of L4T r32.3.1 and I don’t see this issue. I have a slightly older board version (A02), but that shouldn’t matter.

$ fdtget /boot/dtb/*.dtb / compatible

Can you tell me exactly how you flashed the board? Or are you using the SD card image? Ah looking at the SD card image there is no /boot/dtb directory so that will be a problem if you are using this image. Please confirm. We will look into a fix for this.
