Hi,all

Now, I work in DM368 VPBE user-defined-mode with YCC16, and I allocate a buffer,address is : 0x87B00000,

How should I "take good care of" the registers below :

OSD_VIDWIN0OFST, OSD_VIDWINADH , OSD_VIDWIN0ADR.

Hunger for your help!!

Thanks!

    Hi,Nagabhushana

    Thanks for your reply!

    I set "VMD = 1", use "Not NTSC/PAL/SDTV/HDTV" mode(YCC16), and I get the output signal now, however, the device DM368 inserts some V-blanking or

    H-blanking signals into my output data ( Output from YOUT & COUT),so I doubt whether the address registers configuration is OK? Or there are some other

    registers I miss?

    I setup the address registers like below :

     OSD_VIDWIN0OFST = (0x00<< 9) | (704 >> 4);// resolution 704 x 576
     OSD_VIDWINADH = ((tmp_addr >> 16) & 0xFFFF); // SDRAM start address higher 7bits
     OSD_VIDWIN0ADL= tmp_addr & 0xFFFF; // VIDWIN0ADL SDRAM start address low 16bits

    tmp_addr = 0x87B00000, is my valid SDRAM address.

    Hunger for your hellllp!

    Best regards.
