Hi Sylwester,
Sorry the extreme delay in replying..
I using BSP from friendly arm.
SInce i am new to embedded linux, can you tell me how to install a 0v7670 driver for mini2440?
I currently modified the v4l2 driver(for ov9650) written by Vladimir (http://code.google.com/p/s3c2440camera/) to suit the 0v7670. But i am not able to get a perfect image from the camera. Can you point me to tried and test v4l2 driver for 7670?
Thanks,
Anvesh
