We use customized board based on imx6q sabreai board and linux OS. HDMI schematic(pin mux and all passive element) is same with sabreai. But we don't use audio function(hw codec doesn't be applied)
When we use same binary image, sabreai works but customize board doesn't work(but hotplug is detected).
If hw codec doesn't be applied, Doesn't HDMI work?
If we have to imx6 zeng modify kernel source, would give me the check point?
Thanks and best regard.
