Hi,

It seems like a new thread has been created for the same query in this thread, ADV7613 CEC programming - Q&A - Video - EngineerZone (analog.com). We have already posted our response here. Kindly check.

It is advised not to create duplicate thread since it would be difficult for tracking.

Thanks very much for understanding.

Hi Dharani S,

It's a similar question, but I still can't find where to get the physical address of ADV7613.

In any register or EDID data blocks.

Thanks

Hi,

Please find our comments below.

SPA - Source Physical Address:
This is part of the CEA block in the EDID memory. Basically, it sets up CEC addressing which needs to change for each RX port.

Source to Port A will read the EDID as-is.

The source to Port B will read the EDID data and as the EDID data is read, the byte stream will be modified on the fly at the SPA_LOCATION with the values defined in SPA_PORT_B. The block checksum will be updated also on the fly.

SPA is just 2 bytes, Assume SPA_A = 0000 hex, then SPA_B might be 0001 hex
