Can't boot ARM64 on Raspberry PI 3 B+

[Video Mike <wb9ypa%fourway.net@localhost>]

Greetings,
Is NetBSD v8 supposed run on the Raspberry Pi 3 B+ board?  I tried as 
many images as I could find that pertain to the
Raspberry Pi's and I could not get any of them to boot.  One of them I 
at least could get the colorful slate with the low
power status symbol in the upper right corner.  If there are any other 
images for ARM that I'm not aware of please let
me know and I'll try them.  I would like to help with this project any 
way shape or form that I can.  I've been running
NetBSD for nearly fifteen years now.  Started learning it on the Atari 
TT030.


Thank you,
mike
