DM368 VPBE non-standard mode,YCC16 output

Hi,all

 I encounter a very tough problem(to me) in using DM368 VPBE non-standard mode(output digital YCC16，not RGB，-)_(- ).

I configured a lot of registers(VENC&OSD) about non-standard mode,such as setting VENCCLK=27M,

resolution=720*576,VIDWINOFST=0x1000 | (720 >> 4), VIDWIN0ADH=0,VIDWIN0ADL=0,etc.,

and then I put data(CbYCrY:84 76 240 76) into 0x80000000(SDRAM) and enable VENC,

but there's nothing in my LCD panel except a black colour with blink.


 I am a "BIG FISH" in using VPBE non-standard mode, although I have configured standard mode successful。

So, I hope someone could give me a sample, tell me which registers I need to concern, show me how to

configure the registers(needn't LCD driver).

 

 Maybe my require is too much......


 Thanks and regards.
