i.MX28 cpu temperature measurement.

Hello, dear Freescalers!

Please, help me with a little trouble. I'm trying to measure the temperature of CPU.

All needed modules in menuconfig and kernel_menuconfig, as I think, are switched on (hwmon, iio, lradc, collectd, libsensors, thermal).

In .dtsi :

iio_hwmon {

  compatible = "iio-hwmon";

  io-channels = <&lradc 8>;

};

But my directories /sys/class/hwmon/ and /sys/class/hwmon/ are empty. What's wrong with it?

Regards

Vladimir

Thank you, Yuri.

If I understand, it's register way. But I asked about Linux way, using OpenWrt drivers and packages.

Hi,

NXP / FSL BSP does not support this feature :-(

Regards,

Yuri.
