'I was reading the source file of ov2718_mipi.c more carefully and noticed that a lot of registers it attempts to write to does not exist in the ov2718 manual!"
my ov2718 datasheet has version 2.03, july 2001 year ))) 18 year old! and datasheet describe 2720 sensor! not 2718 ))
What the pixel rate are you setup? (which registers used for this?) table rate for ov2718 - https://yadi.sk/d/rithIqzt6W_Rqw
What the input clock frequency (for ov2718) are you setup in clk-sun8iw12.c file or sys_config.fex?
