The new user guide is not available yet. I have attached the new schematic.1070.SV600901B_Schematic.pdf

Looking at the picture, it seems that the mode_sel strap is not set on the 928.

BTW, we have DS90UB929 which takes in HDMI input and convert it to FPDLink. You could possibly skip the HDMI to LVDS converter with DS90UB929.

Best Regards,

Hello Edward,

THe MODE_SEL strap (controlled by S5 on the EVM) has 9 positions which match table 6 in the datasheet. Please refer to the datasheet to figure out which option to select.

Best Regards,
Casey
