My product production plan is based on HDMI2C1-14HD designed Micro-HDMI interface, the software system is Ubuntu
I have encountered a problem, when I connect the MicroHDMI interface, the system can not read the EDID normally, showing 0X50 no ACK;
But the same circuit, when I use the HDMI-A interface design, I can correctly read the display's EDID. I have not found the cause of this problem.This is the schematic of the HDMI-A interface.
This is the schematic of the HDMI-Micro interface.

This is strange, schematics on SCL and SDA seems OK. I saw a difference between schematics: connection between GND and PGND. Perhaps a tests with a BLM to connect PGND and GND can be tried on Micro HDMI schematic.
