w1-gpio cable connection

signux voß

Hi,

I try to connect a DS1820 (Temp-sensor) with the expansion dock(inc. onion omega).

I have build my own openwrt with this tutorial.
I have added the modules w1-gpio and w1-therm.
The w1-* modules are loaded.

On the pins GND/3.3V/GPIO1 I have connected the DS1820 inc. Resistor as I use it on Raspberry PI.

But I don't find the output of this sensor via "ls /sys/bus/w1/devices". No device is available.

Have anyone a idea why? Must I configure a kernel parameter to use the GPIO for 1-Wire?

Thanks
