OK, now I'm sure I'm stuck

I did everything they wrote on nioswiki

I wrote a driver to my leds ip, gave it the base address from SOPC builder

gave it a major number and the neccesery functions

added the neccesery adjustments to the kconfig and makefile files

when I config my kernel I can see my driver in devices driver --> misc (where I put it)

but when try to insmod my driver it says the my driver's .ko file does not exist

and now I&#39;m stuck :<

does anyone have an example of a driver module?

and also, how do I use a device file in an app after opening it?

thanks,

Asaf
