In case "Parse EDID Data" failed on HOST controller, what is recommended process here?
Just to toggle 0x41 1(Power Down) -> 1(Power up)?
Yes. As per your understanding, it has to be powered up via R0x41.
Please find our below comments for the proper parsing of EDID data.
We have handled all EDID processing in software and recommend you use our software driver as reference at Evaluation board software
