Install Failure RPi 4

["Thomas D. Dean" <tomdean%wavecable.com@localhost>]

I have an RPi 4b using a USB flash drive and RPi OS.

I attempted to install NetBSD 10 on an SD card.

On the RPi, I downloaded arm64.img.gz and extracted arm64.img.

> ls -l arm64.img
rw-rw-r-- 1 tomdean tomdean 1582301184 Apr  3 15:02 arm64.img

I used dd to copy the image to an SD card.

> dd if=armv7.img of=/dev/mmcblk0 bs=1m conv=sync

After this, the SD card looked OK for the RPi.

I shut down the RPi, removed the USB flash drive. I connected a mouse, 
keyboard, and display, and powered up with the SD card inserted.

The red LED is on continuously. The green LED flashed for ~1 sec, was 
off for ~1 sec, flashed for ~2 sec, was off for ~2 sec, flashed for ~3 
sec, then was off (5 minutes). The display flashed then was blank, again 
(5 min).
