Great :) > but touch screen is not working, please help me. How does it not work ? Do you have some events, is it sending bogus inputs or is it just that is it barely usable ? If you have no input at all, I guess the touchscreen controller is the AD7846, check that you have the proper driver compiled with the kernel. If you have bogus input values, you should check that the touchscreen orientation wrt the screen is correct. Like I was saying, for the 4.3", the touchscreen was upside down, it might or might not be the case for 7". If it is barely usable, then you will have to calibrate the touchscreen.
