Description JJ Day 2021-05-18 03:49:00 UTC

I installed FreeBSD-13.0-RELEASE-arm64-aarch64-memstick.img to a new RPI 3B+. I added packages, users, etc. and ran for a couple of days for burn-in. Everything went well until I tried to boot single user. It froze during the boot and the only keyboard sequence I found that worked was <cntl> <alt> <del>.
I re-booted to multi-user and tried "# shutdown now" to get to single user and had the same result as booting directly to single user mode.
Any suggestions?

Wrong installation file listed. Should be:
FreeBSD-13.0-RELEASE-arm64-aarch64-RPI.img.xz

I believe you'll find that single user on the RPI requires a
serial connection. Haven't checked comprehensively, at least not
lately, but AFAIK only u-boot and multi-user work with a USB keyboard.
