I know it is possible to have the device in free running mode with no HDMI cable connected but is it possible to force free running mode if active video is being received?
Yes, see CP 0xBF. The output format will be based on Prim_mode and Vid_std selected
How to set the adv7612 register so that LLC,DE and VS go to inactive when the hdmi cable unplug?
when I set it to none free mode ,it always generate those signals when I unplug the cable.
below is my setting :
CP 0xBF = 0x16
CP 0xBA = 0x00
Add wak pull downs on the pins and tri-state the outputs
