Thanks for the response.

From the "cat /proc/devices", I could see "iio" listed like this.

/ # cat /proc/devices
cat /proc/devices
Character devices:
1 mem
4 /dev/vc/0
4 tty
5 /dev/tty
5 /dev/console
5 /dev/ptmx
------
250 iio
251 pps
-----

I could see few other deices @ /dev/xxxx. CONFIG_DEVTMPFS is not set in the def config. I will try it by adding "CONFIG_DEVTMPFS=y" and "CONFIG_DEVTMPFS_MOUNT=y".

Thanks,

Naresh

The kernel is creating your device in /sys. You need to either get udev knowing what
to do to mknod the /dev entry, or check if your kernel config has:

CONFIG_DEVTMPFS=y
CONFIG_DEVTMPFS_MOUNT=y

so the kernel takes care of it for you.
