That's odd, netbsd-9/202002060240Z/evbarm-earmv6hf/binary/gzimg/rpi.img.gz
boots on my Raspberry Pi 3A+ without any changes, the FAT filesystem
does *not* contain bcm2837-rpi-3-a-plus.dtb.  I think older firmwares
load bcm2837-rpi-3-b.dtb even on the Pi 3A+, that explains why it
works, but it's strange that it doesn't work for you.  But to me it
seems that nothing is needed on netbsd-9.

As in my last mail, I only tested the serial console, not HDMI out.
