Hi Neil,


Sorry for the delay. Thanks for your update that HDMI IP seems to be working prior to feeding input signal. Currently you are working on the issue with the IP when input signal is fed to the RX. Please feel free to let me know if you would like to further engage our HDMI IP expert to further assist. Since I could not duplicate a case from here, you may open a new Forum case specific to HDMI IP RX and let me know the case so that I could help to expedite the routing. Thank you.

Thanks.

I'm still uncertain why the transceivers wouldn't calibrate in the full design, but it seems more useful at the moment to pursue getting a signal lock on the HDMI receiver-only design, and deal with the complete design issues only after that is resolved.

I'll post here once I open a new case.
