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 :) >=20 > I'm excited to see that you're making progress, nonetheless! 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.)
