Thanks for your reply!
1. Here this connector I used. Hi253 Camera connect with DM3730 AP Module
through I2C Bus and Parallel Interface (CAM D2,...,CAM D9) as above image.
2. Here Source code Hi253 Driver that I use:
https://github.com/allwinner-ics/lichee_linux-3.0/blob/master/drivers/media/video/sun4i_csi/device/hi253.c
Have you give me any advise?
