Cubieboard 2 / Cubietruck: 1wire with DS18B20 working?

Postby crashmaster » Sat Feb 22, 2014 4:48 pm

Would be nice to get the DS18B20 temperature sensor working on my cubieboard 2.

I use kernel 3.4.79.

My sensor is connected with 3 wires and a 4,7 K pullup - the classical way. It worked on RPi before and after my tries on CB2, there shouldn't be any hardware problems. I use gpio 61 and checked the connections several times.
gpio61 is activated in the fex file, i also tried some combinations i've found for w1 there. And yes, i didn't forget a fex2bin after each change and did a reboot each time. ;)

I tried all possible module parms: strong_pullup switched off, internal pullup on or off, always for gpio=61.
/sys/bus/devices/w1 has all the contents needed but never showed a "28-....", the sensor itself.

Is there anybody out there who got this working on a CB2 or Cubietruck?

Thanks in advance and regards, CM
