OK, nightmare is a bit of an exaggeration, but the RPi B2 and her Tangerine PiBow case arrived today, so I installed the basics are per the Zoe instructions, and did a quick test run which failed almost instantly because the RPIO PWM didn’t recognise the RPi B2. That’s not really a surprise – what surprises me if that it hadn’t barfed on the B+ and A+ as the RPIO code dates back to March 2013. Looks like I’ll have to fix this and see if metachris will add the fix to the master.
Turns out I’d fixed this already, and then forgotten about it. I’ve uploaded the tweaked version to my GitHub along with updating Zoe’s build instructions.
