Yes, this is really annoying. For getting the BeagleBone Black working = with 13-CURRENT, I need to replace the DTS at sys/gnu/dts/arm, which is = currently v5.6, with v4.2 (r347365), and then rebuild the kernel. > If you want to stick with armv7/32-bit stuff, I would say your best = bet > for long term freebsd support would be Allwinner or imx6. My concern is not 32 or 64bit. These unit controllers will never ever = run a desktop environment, so it won=E2=80=99t even come close to touch = any 32bit memory limit. That said, 64bit is not exactly needed but would = not harm either. > I keep hearing mumbling about freebsd throwing all 32-bit support > overboard in a future release.

Well, if longterm support for 32bit of FreeBSD is questionable, this = would be a huge road block for the BeagleBone AI. I will also respond to = your other message. Best regards Rolf
