Close often isn't good enough. SoCs don't have self describing hardware
like PCs do and so you need a devicetree file that describes your
hardware. Grabbing an "old" or "close" devicetree file has never worked
for me.

I think that the people who have had access to a Jetson Nano in the
past (such as myself) haven't known enough about how to get ARM SoC
systems running to get this to work. 

I now know more than I did and I still have my Jetson Nano. I have just
finished messing about with another ARM board, so I have some time to
help out with this. I would certainly like to get NetBSD running on my
Jetson Nano.

I'm expect that U-Boot will only support serial over USB and you are
going to need to use U-Boot's console, at least at first.

Probably. The Jetson Nano boot process is a little more complicated
than some other ARM SoCs that I have used.
