We're using the 7611 and 7622 as a repeater product.
I got into a situation where the 7611 and 7622 are both happy with repeater HDCP . That meant we got into 3rd part of authentication OK, I can see the Ri/Ri' checking fine and no error.
However the 7611 even though it is happy with HDCP, sometimes there are NO video coming out of the 7611 . I am guessing it has something to do with the RX freerun state mess up. I don't understand the freerun stuff.
What I like to do is enable video to come through after we get to 3rd part of HDCP authentication successfully with freerun disable. I program the VIC, checking to see HPD is raised, enable TMDS termination etc. I tried to do it but nothing seem to work.
Do you have a script that enable 7611 to allow video to coming of it and give to me ? I don't need anything with HDCP as it already working for me.

There is a section in the "ADV7611 Recommended Register Settings" document on the method to turn on free-run on the design support files page: http://ez.analog.com/docs/DOC-1745
I am just adding system clarification to this question. Customer's system is a modular display wall, with each module having the signal flow: ADV7611 Rx (handling/decrypting HDCP) --> processor block that drives local panel and provides throughput HDMI Tx out --> ADV7622 TRx (with Tx side handling/encrypting HDCP). Hence, the HDCP Repeater system is formed between ADV7611 and the Tx side of ADV7622.
