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 of the user map is 1, it means component processor is free running. In addition, there were many user registers becoming 0x60. Can 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
