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 On Wed, Jun 1, 2016 at 9:41 AM, [off-list ref] wrote:

We are integrating one sensor driver in to LE platform. After addingsensorquoted
driver, it is creating device @ /sys/bus/iio/devices/iio:device0,1,2.quoted
Sensor driver makes use of IIO subsystem framework. We are not seeing iio device creation @ */dev/iio:device0*,1,2The 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.
