insmod does not create a /dev/...
 

I am using kernel version 2.6.30 for ARM core
i am trying to make char device.
i am using the functions register_chrdev, class_create and device_create
to register char device.
i am not able to find the device node in /dev

Any idea???

thanks in advance

Is this a programmer question?

@sekaran

have u checked what values have been returned by the functions mentioned by u. Have they returned some negative value or positive value ?

In an embedded ARM system, it is likely that udev is not running.
In that case, you would have to create the device node by hand.
