Our products have used adv7441a as a DVI input chip, resently a device's adv7441a outputed black screen with 1080P DVI signal inputing. I found the value of the 0x12[6] of the user map is 1, it means component processor is free runningIn addition, there were many user registers  becoming  0x60Can anyone explain why the adv7441a entering CP free running state and how to solve this problem? Thanks a lot! 

 

notes: Attachment is the value of the exception register
