ADV7611 without any HPA and EDID

Hello,

 

I have a video source that doesn't have any Hot Plug and DDC CEC signals,  I handled those relative pins as  stated at the user guide of ADV7611.

For example HPA_A , DDCA_SDA is left float and  DDCA_SCL is connected to ground via 10K resistor and so on.

 

I am trying to receive 720p60 signal but I cannot get any signal. I am trying to init the 7611 as the scripts at the design support files. In my custom circuit,  ADV7611 is connected to a blackfin 609. I am trying to modify and use the 7842 drivers in the EI3 decoder board.

 

If anyone can hint what I might be missing, it will be very helpful

 

Regards,

 

Hazar
