I still can't get wifi up. Both with wheezy and jessie with kernel 3.4.
For exmple in wheezy (modprobe and adding an entry in /etc/modules has the same effect doesn't it? I tried both versions):
root@bananapi:~# modprobe bcmdhd

ERROR: could not insert 'bcmdhd': No such device
Also I'm not sure which image to use at all. For my project I need wifi in AP-mode and I2S. Which image would you recommend?
