Hi ,


We have designed our product using ADV7513 HDMI TX.I have programmed the register values as mentioned in "PROGRAMMING GUIDE- SECTION 3 - QUICK START GUIDE". But i am not  getting video output from ADV7513.


Below are my observation.

PLL status is locked.

Able to get VSYNC interrupt.

VIC to Rx(REG 0X3d)=000100 = VIC#4:720p-60, 16:9.

Actual VIC Detected =000010 = VIC#2: 480p-60, 4:3.


I have attached the schematics of HDMI TX section for reference.


Can you suggest me what should be taken care to get video.



I have configured only video section of processor.Audio section of processor have not configured yet.
