MPC5645S VIU can't enter VSYNC Interrupy

Question asked by i no on Sep 28, 2018

I'm new to VIU module. We use adv7180 to connect 4 cameras. 

I think configuration for adv  is fine. I get blue screen but cannot get video displayed.

Using debug I found I cannot enter vsync interrupt.

signal for V_Clk etc is  fine.


Can anybody give me a hint, what might be wrong?
