Jetson-TX2 - updating device-tree

Yes, that’s definitely incomplete. Check the log file for the u-boot-bup-payload do_deploy task, which should be at $BUILDDIR/tmp/work/jetson_tx2-poky-linux/u-boot-bup-payload/1.0/temp/log.do_deploy (or something similar, depending on your distro configuration). I have seen cases where the BUP generator script encounters (and logs) errors but doesn’t fail out the execution of the task. That could be happening here.
