Hi experts,

   I follow ADV7850 evaluation board to design my circuit. Now my board is on test for CVBS / YPbPr/ S-Video/VGA input to HDMI out application. My test is below:


1. Power on 


2. Use AVES Blue 3.03 to send configuration scripts : ADV7850ES2-Ver.3.08d_AVEB.txt


3. test reuslt: 

(1). CVBS/YPbPr/S-Video is OK. The Script 1,3,4 is Pass. It could receive analog video and output to HDMI video.

(2)  VGA is NG. (script 7). I has no image to HDMI.


How could I check the VGA input?

the register : CH1_STDI_DVALID  = 1 (read from AVES Blue tool)
