dm6437+tvp5158实现4chd1的配置及问题

Other Parts Discussed in Thread: TVP5158

请问一下,在5158中有可以实现54mhz的4chd1输出,

输出的数据是通过dvo-a和dvo-b口输出,现在我的操作是

对于5158的配置已经写好寄存器0xB0的值为0xA8,0xB1的值为0x10。

对vpfe的配置为:

static  PSP_VPFECcdcConfigParams ccdcParams =
{
     FVID_CCDC_YCBCR_8,   //FVID_CCDC_RAW_FORMAT,                 /* dataFlow     */
     FVID_FRAME_MODE,//                   /* ffMode       */
    2500,                                /* height       

    728,                               /* width        */
    (728*2),                           /* pitch        */
    0,                                  /* horzStartPix */
    0,                                  /* vertStartPix */
    NULL,                               /* appCallback  */
    {
        PSP_VPFE_TVP5158_Open,         /* extVD Fxn    */
        PSP_VPFE_TVP5158_Close,
        PSP_VPFE_TVP5158_Control,
    },
    0,                                   /*segId         */

 }

问题:经过试验,还是没有数据从5158出来存到分配好的缓冲区里
