HDMI Bringup issue in Costum board

[aabhishekoct18]

Hi  Team 

We made  one custom board based  on iMX 6  solo , first  time we  are doing bring up , at the  time of boot up we are able  to see  NXP logo  but  after that we are continuously getting even of  HDMI plug in and  plug out every 1-2 sec  . Same Display and cable if  we are  using everything works  fine.

1) Please  check  schematic once if  any change is  required  ?

2) Please  explain me or provide  me some documents which can explain me flow  of events so that i can  probe  everything  and  try to  figure out where is  actual issue ?

HDMI schematic example can be found in Sabre SD design files

Design files, including hardware schematics, Gerbers, and OrCAD files.
