Hi,all:

     We use adv7441a connectted with dm6467, the  mode of adv7441a works BT1120 ( bt656 16 bit yuv 422)。We set adv7441a 720P-60 with YPBPR input, we can get PCLK  74.25MHZ , the data bus has data, it can be seen by logic analyzer. The data has EAV/SAV.But we can not get data from dm6467. The dm6467 setting:

        {"720P-60", 1280, 720, 60, 1, 0, 362, 1280, 1, 26, 746, 0,  0, 0, 750, 0, 0, 1},

struct vpif_channel_config_params {

        char name[VPIF_MAX_NAME];       /* Name of the */

        u16 width;              /* Indicates width of the image for

                                   this mode */

        u16 height;             /* Indicates height of the image for

                                   this mode */

        u8 fps;

        u8 frm_fmt;             /* Indicates whether this is interlaced

                                   or progressive format */

        u8 ycmux_mode;          /* Indicates whether this mode requires

                                   single or two channels */

        u16 eav2sav;            /* length of sav 2 eav */

        u16 sav2eav;            /* length of sav 2 eav */

        u16 l1, l3, l5, l7, l9, l11;    /* Other parameter configurations */

        u16 vsize;              /* Vertical size of the image */

        u8 capture_format;      /* Indicates whether capture format

                                   is in BT or in CCD/CMOS */

        u8  vbi_supported;        /* Indicates whether this mode

                                     supports capturing vbi or not */

        u8 hd_sd;

};

     So we do not know how setting of adv7441a is set, please help,thank you!
