Another problem I'm seeing with your "wiring diagram". You're powering the sensor via 3v3, but you still have the parasitic power resistor in place. It is my understanding if you're wanting to power the DS18B20 from the dataline. In whcih case the resistor would be between Vdd, and DQ pins (pins 2

Thanks! Could you tell me where is the cap on the board? Already read the BBGW's SCH, but still couldn't figure it out And do you think this is the problem caused by specific kernel versions (I'm using ubuntu 16.04, 4.4.12-ti-r30)? I assume using SPI0 for communication is really common
