A lovely gift that I received for Christmas (2020) was one of CanaKit’s Raspberry Pi 4 kits that comes with an aluminum case that functions as a heatsink, allowing the Pi’s ARM processor to be passively cooled even during high load. At the same time as I began exploring the Pi, I was learning everything that I could about the FreeBSD operating system.
When I first installed FreeBSD on the Pi, I had to use a special bootloader atop 13-CURRENT. The installation was not complicated, but it was far from smooth. I learned what I needed from the #freebsd-arm mailing list, and I sent a message to #freebsd-questions with a summary of my findings.
In the weeks leading to 13-RELEASE, the #freebsd-arm mailing list was ablaze with a heroic collective effort to ensure that a flawless image for the Pi 4 was available on the actual release date. I am here to say that it was a success.
With FreeBSD 13-RELEASE, almost everything works on the Raspberry Pi 4 out-of-the-box. The Pi either can be used with a monitor, keyboard, and mouse via the HDMI and USB ports or accessed remotely via the RJ-45 (Ethernet) jack and OpenSSH—all of which is configured by default. Since 64-bit ARMv8 is now (as of 13-RELEASE, in fact) a Tier 1 platform for the FreeBSD project, a large percentage of packages in the official repository are available for easy installation on the Pi 4 (‘pkg install _’).
I have used the Pi 4 with FreeBSD 13-RELEASE for a range of tasks. Most commonly, I use it for Mumble voice communication (as a Murmur server) and for 24/7 continuous access to my favorite IRC channels on Libera.chat (including #freebsd, #freebsd-desktop, and #freebsd-wiki) by way of a Weechat session in tmux.
If you, too, might like to use FreeBSD 13-RELEASE on the Raspberry Pi 4 as a perfect miniature homelab, start by reading the Raspberry Pi page in the FreeBSD Wiki. Then, download the official Raspberry Pi 3/4 image and burn it to an SD card. Do not forget to change the passwords for the root and ‘freebsd’ accounts (which are listed in the Wiki entry). Enjoy the elegant simplicity.
Deus vos benedicat,
