I'm using the ADV7280 Evaluation Board with the "DVP Eval Latest Source 10-14-11" software. I've modified the "Autodetect_CVBS_Single_Ended_In_Ain_1_YPrPb_Out.py" script so that the ADV7391 outputs CVBS instead of YPrPb. I've attached my modified script. My problem is that about 50% of the time the screen appears without color. The status registers are as follows: Status1 = 0x0D; Status2 = 0x00; Status3 = 0x69. If I disconnect the video source and then reconnect it the color works and Status1 changes to 0x0F. What is wrong with my script?
