Hi, I am trying to use ina219 sensor (http://www.adafruit.com/products/904) with linux kernel driver on beaglebone black. I want to use device tree overlay to use the sensor. I follow kernel indications ( http://lxr.free-electrons.com/source/Documentation/devicetree/bindings/i2c/ina2xx.txt) and the sensor works as expected. But adafruit board use 0.1ohms and default driver value for shunt-resistor is 10mOhms so return value are wrong. I want to modify value in device tree as indicated ina219@40 { compatible = "ti,ina219"; reg = <0x40>; shunt-resistor = <100000>; }; but changing shunt-resistor value does nothing. The sensor is always create with 10mOhms value ina2xx 1-0040: power monitor ina219 (Rshunt = 10000 uOhm) How can i change the shunt-resistor value to get the proper return?
Good question. This functionality was added mid-2013. What is your kernel version ? Guenter _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
