ADV7510 HDCP error

I'm bringing up the ADV7510 on a custom PCB. I'm able to receive EDID data. My ISR is clearing VSYNC interrupts. No video yet.

 

When I enabled HDCP, register 0xC8 is reporting b0100 0011.

 

Which translates to:

HDCP State: 0011 - Initializing HDCP

HDCP Error:  0100 - I2C Error (usually no-ack)

 

What does this error mean? Does this point to a potential hardware problem with the I2C going to the monitor? Or is this the I2C going back to my CPU.

 

Thanks.
