Help with Audio: ADV7511 Xilinx Evaluation Board Ref Design

Question asked by bitscream on Feb 6, 2014
Latest reply on Apr 10, 2014 by DragosB

I am trying to implement this.

 

http://wiki.analog.com/resources/fpga/xilinx/kc705/adv7511?force_rev=1#running_demo_sdk_program

 

I have downloaded the HDL Ref Design Zip and the no-OS Software Zip for Zedboard.

 

Before building the project using the provided library files and Source files, I was trying to run the evaluate demo ( .bat) file for the Zedboard.

 

I can see the static image ( the video data) and also change the resolution. But I cannot hear any audio output.

 

Is there something I am not executing? Does the demo file include any audio data?

 

I can see it says "un-mute" video and audio.

 

Any help with this is appreciated. I can provide you with more data based on your request.

 

The following is the EDID data on Tera Term.
