EVAL-7842-7511P Error: "HDCP i2c failed error received"

Question asked by jim_philly on Apr 1, 2017

I have an EVAL-ADV7842-7511P evaluation board, non-HDCP version.


I am attempting to feed composite (CVBS) video into the board and capture the HDMI output using a Blackmagic Intensity 4K PCI express card.


When there is an active analog output on either the s-Video, or the composite input, and I switch to one of these inputs via command line terminal window, I get a continuous, repeating string of errors that read:


-Tx: ##:### HDCP i2c failed error recieved


The "##:###" portion counts up to 60:999 (in random increments) before resetting to 0:000.  This continues until I physically disconnect the s-video or composite source, or until I attempt to input a command to the serial terminal window.  Here is a sample of the messages leading up to the string of errors:

I am, however, able to get the eval board to output video to my Vizio television without any problem.  There seems to be some issue specifically with the interaction between the eval board and the Intensity card.  Maybe the intensity card.


Using VirtualDub, I get a noisy, offset version of the signal (as in the attached photo, you can make out the splash screen from the composite output of my DVD player).


Any ideas?  Thanks in advance.


Other notes:

- Board control via USB interface, using PuTTY as a serial terminal window

- Tried different analog sources -- JVC SVHS VCR, Pioneer CLD-95 Laserdisc player, Panasonic DMR-ES10 DVD recorder.
