The IIC configuration list for the ADV7511 in KC705

I am working in a simple design in XIlinx KC705 EVB to display video through ADV7511. Based on the hardware design of KC705, only 18 bits data bus is connected between FPGA and ADV751, therefore, I try to transimit the video with 16 bits YCbCr 4:2:2 style 1 based on the page 24 table 7 of the ADV7511 hardware user guide. I wrote the IIC configuration list by myself.

 

Then I use the test pattern generator (TPG) inside the FPGA as the video source, but when I saw the video showed in the monitor, I found the video looks much dark then expected and the color is not correct. The design is pretty simple and I already verified with Xilinx that there should be no problem in their TPG. So I doubt there should be something wrong in my IIC configuration list, which may configure the ADV7511 not work in the proper mode.

 

I just wonder is there any reference IIC configuration list for the KC705 that I can take refer? 

 

Thanks very much.
