Dear vatti, You should take a look at these files: Micro 2440 User Manual (search for "led driver" and "hello module"). Download linux kernel from download area and look for "linux-2.6.32.2/drivers/char/mini2440_leds.c" Download "examples" from examples and take a look at "leds" example. Using these files above you will be able to understand and built your own device driver. Regards.
How you can find major number for leds? How ioctl function can related in leds driver? Can anyone explore on these? Thanks in advance Alex
