Hello everybody, current problem...
We have the ADV7181C. I am using the CP to capture a nonstandard monochrome format that resembles RS-170. I am 2x oversampling it.
If I have video on, I can write to 0xBF and force output of default colors (blue screen of death).
I can set the Free Run Line Length to an appropriate value.
When I have FR_LL set, when I disconnect video I don't get the blue screen. The output just dies. It comes back when I plug it back in.
If I set FR_LL to the wrong value, it locks up the same way; when I fix it, it comes back. This proves that the line length threshold detection is working correctly (or trying very hard).
How do I get my blue screen of death back?
