hi3516dv300接1024x600 MIPI屏(EK79007AD)

用sample_hifb跑有闪屏的现象，打mipi_tx的partten，只有点闪线的问题，怀疑是VO哪里还没配置好
MIPI的时序如下
[code]combo_dev_cfg_t MIPI_TX_1024X600_60_CONFIG =
{
    .devno =  0,
    .lane_id = {0, 1, 2, 3},
    .output_mode = OUTPUT_MODE_DSI_VIDEO,//OUTPUT_MODE_DSI_CMD,//OUTPUT_MODE_DSI_VIDEO,
    .output_format =OUT_FORMAT_RGB_24_BIT,// OUT_FORMAT_RGB_24_BIT, OUT_FORMAT_RGB_16_BIT
    .video_mode =  BURST_MODE,
    .sync_info = {
        .vid_pkt_size     = 1024,
        .vid_hsa_pixels   = 20,
        .vid_hbp_pixels   = 140,
        .vid_hline_pixels = 1344,
        //hfp=160
        .vid_vsa_lines    = 3,
        .vid_vbp_lines    = 20,
        .vid_vfp_lines    = 12,
        .vid_active_lines = 600,
        .edpi_cmd_size    = 0,
    },
    .phy_data_rate =360,//463,//358,//307,// 77,//311,//486
    .pixel_clk = 51287,//51669,//51287,//51669,
};[/code]

VO的时序是自定义的
[code]        stVoPubAttr.stSyncInfo.bSynm =1;
        stVoPubAttr.stSyncInfo.bIop  =1;
        stVoPubAttr.stSyncInfo.u16Vact =600;
        stVoPubAttr.stSyncInfo.u16Vbb  =23;
        stVoPubAttr.stSyncInfo.u16Vfb  =12;
        stVoPubAttr.stSyncInfo.u16Hact =1024;
        stVoPubAttr.stSyncInfo.u16Hbb  =160;
        stVoPubAttr.stSyncInfo.u16Hfb  =160;

        stVoPubAttr.stSyncInfo.u16Hmid =0;//1;
        stVoPubAttr.stSyncInfo.u16Bvact=600;//1;
        stVoPubAttr.stSyncInfo.u16Bvbb =23;//1;
        stVoPubAttr.stSyncInfo.u16Bvfb =12;//1;
        stVoPubAttr.stSyncInfo.u16Hpw =20;
        stVoPubAttr.stSyncInfo.u16Vpw =3;

        stVoPubAttr.stSyncInfo.bIdv =0;
        stVoPubAttr.stSyncInfo.bIhs =0;
        stVoPubAttr.stSyncInfo.bIvs =0;[/code]

VO时钟
[code]#if 1       
        VO_USER_INTFSYNC_INFO_S pstUserInfo={0};
        pstUserInfo.stUserIntfSyncAttr.enClkSource=VO_CLK_SOURCE_PLL;  //VO_CLK_SOURCE_LCDMCLK  VO_CLK_SOURCE_PLL
#if 1
        pstUserInfo.stUserIntfSyncAttr.stUserSyncPll.u32Fbdiv = 101;//5837414;//5837414;52000
        pstUserInfo.stUserIntfSyncAttr.stUserSyncPll.u32Frac= 0;
        pstUserInfo.stUserIntfSyncAttr.stUserSyncPll.u32Refdiv =2;
        pstUserInfo.stUserIntfSyncAttr.stUserSyncPll.u32Postdiv1 =6;
        pstUserInfo.stUserIntfSyncAttr.stUserSyncPll.u32Postdiv2 = 4;
//        pstUserInfo.stUserIntfSyncAttr.u32LcdMClkDiv=5837414;
#else
        pstUserInfo.stUserIntfSyncAttr.u32LcdMClkDiv=5671489;
#endif
        pstUserInfo.u32DevDiv = 1;       
        pstUserInfo.u32PreDiv= 1;        [/code]

有大神指导下么？
