What is the phenomenon of your board now?hdmi no picture?

Direct use of hdmi to connect the display, with hdmi to VGA is not. Test dk1 with hdmi to VGA and display

Can you post the hdmi circuit diagram?

It seems that this esd chip has a bug, you can try another hdmi display and try it, the esd I used for the first time also has problems
