Hi,
Here are some feedback from our team. Please help take a look. If something is wrong, please help point out.
There seems to be two issues here:
i. HDMI hotplug is not stable with HDMI to SDI converter.
ii. With Forced EDID, there’s graphical corruption at specific locations on the screen.
You been trying to resolve this issue for a long time. Could you give brief comment to summarize what you’ve done so far?
For (i), I am ignoring all the basic things like cable quality, checking with multiple monitors or SDI converters, etc. assuming that these things would be the obvious ones, and customer might have already tried.
I would suggest checking the voltage levels of the VDD 5v regulator on Jetson board (at the HDMI port). If there are slight variations in voltage, it might be causing the converter to toggle hpd?
For (ii), it’s surprising that the issue happens only at specific spots on the screen. Probably composition issue. Is those garbled location random one or only to fixed location?
Also, can you try with a lower resolution (may be 720p) to see if the behavior is different?
