ADV7511P output enable

Question asked by psusi on Sep 6, 2017

I have the ADV7612-7511P eval board and running this script gets me some kind of output.  I took only the writes to address 72 and had my code write those same values to the 7511P on our own board, read them back to verify they took, and it does not generate any output.  We have not connected the I2C lines to the HDMI connector but it does not look like this script tries to communicate with the monitor anyhow.  We also do not have HPD connected, but I added a write of 80 to register D6 to force HPD.  Any idea why it isn't powering on?
