make menuconfig: Device Drivers? ---> Graphics support? ---><*> Support for frame buffer devices? ---><*>?? S3C2410 LCD framebuffer support device node: /dev/fb0 file: drivers/video/s3c2410fb.c Another configuration item in the same page is: LCD select (7 inch 800x480 TFT LCD)? .then 7 inch lcd will work. Do not worry about touchscreen,we just do calibrating when system on and it will work.
