I am trying to configure the ADV7611 HDMI receiver through EDID data to reconfigure a GoPro camera Hero 3 to just get 720p60 as incoming resolution, however at this point this have been unsuccessful.
I have tried to reconfigure the GoPro camera adding an EDID data which is only updated for 720p60 using EDID editor. Everytime that I need to get video from GoPro camera, I set the HPA pin as low, I load the EDID data to the internal EDID RAM and finally I set the HPA pin as high. According to my understading, this should do that GoPro reads the new EDID which is updated for 720p60 and reconfigure itself, however it is not working so far.
Does anyone have any idea about how to reconfigure a GoPro camera from ADV7611 HDMI?
