I'm experimenting with running FreeBSD on a BeagleBone Black (revision C).
See also my BeagleBone Black notes.
Initial installation
- Get a compressed snapshot (.img.xz file) from FreeBSD's ARMv6 snapshots[/url on ftp.freebsd.org. At the beginning of July 2015, when the latest production version was 10.1-RELEASE, I first tried a 10.1 snapshot. Howerver, it was unable to fully boot and mount the root file system. I asked about it on Freenode IRC (channel #freebsd-embedded) and was advised that 11-CURRENT was the better choice for ARM support, at the moment. Indeed, the June 30th 11.0-CURRENT snapshot works like a charm.
- Uncompress it (e.g., with 7-Zip).
- Use a disk image writing program (e.g. Win32DiskImager) to write the image to a micro SD card. I use a 64 GB card via a USB adapter in my PC.
- With power off, insert the micro SD card in the BBB.
- Hold the boot button (it's the button near the card) and plug in the BBB. Keep holding the boot button for a few seconds to be sure it boots from the micro SD card. It will remember to boot from the card until the power is cut. Don't worry, there's a way to make it always boot from the SD card, but you don't want to do that until you're sure the OS on the SD card is working.
This is what I got the first time I booted 11-CURRENT:
