Oh, I could be very mistaken- perhaps someone on list could help me understand this- (searching the web isn't helping me here),

Can anyone on list here help me clarify the ARMv7 or ARMv8 architectures?

--
I have a couple of Beaglebone Black boards, I'm unclear if it's ARMv7 or ARMv8, because all the Beagleboard/TexasInstruments literature just says "Cortex-A8".

https://beagleboard.org/black
https://www.ti.com/product/am3358

It's a 32 bit cpu, but no mention of ARMv7 there?

Interestingly, I see there's a ton of new excitement for ARMv8, (SO WISH I WAS THERE!)
https://www.bsdcan.org/2015/schedule/events/549.en.html

yet from searching the net, the ARM page in the FreeBSD wiki currently has no mention of ARMv8,
  https://wiki.freebsd.org/FreeBSD/arm

I may just be searching poorly :)

Me too, will be happy if it compiles!

(I have a nice little applied use for a simple/el-cheapo wireless access point in an odd location, and if I can get this working with OPNsense, I'll be delighted.)

Best,
