Question about ADV7511W

HI ALL~

I connect the ADV7511W and A7-FPGA. If I choose "program device"(board power on and then program from Vivado online, sorry but I don't exactly konw how to expression it), ADV7511W can start up, and the monitor connceted to the ADV7511W has a image. But if I firstly program configuration memory device (FPGA will boot from flash) and then board power up, ADV7511W can't start up.

Is there any require of the system reset time before program the ADV7511W's I2C? Or any other problems?

Thanks for everyone~
