Hi everybody,

     I have a custom board based on i.MX6DL core. On this board ,I have ADV7391 encoder connected to DI1 (DISP1_DAT_7~DISP1_DAT_0) through bt656 which working in NTSC mode. I use Freescale L3.0.35_1.1.0_GA for i.MX6DL core. The FW has patched support of BT.656 and set BT656_IF_DI_MSB from 23 to 7. I want to use this encoder for main display. But the ADV7391 encoder output not correct CVBS signal. Could anybody help me please? What I have tried DI0 (DISP0_DAT_23~DISP0_DAT_16) is correct CVBS signal output.

--u-boot parameters for video mode : "video=mxcfb0:dev=adv739x,BT656-NTSC,if=BT656,fbpix=UYVY16"
