hisi3516dv300 接入bt1120问题

现象:配置属性失败

前段是有FPGA生成的BT1120信号，硬件没有问题，配置不下去能是什么原因呢？
结构体如下：
combo_dev_attr_t MIPI_BT1120_ATTR =
{
/ input mode /
.devno = 0,
.input_mode = INPUT_MODE_BT1120,
.data_rate = MIPI_DATA_RATE_X1,
.img_rect = {0, 0, 1920, 1080},
{

    .mipi_attr =
    {
        DATA_TYPE_YUV422_8BIT,//?????
        HI_MIPI_WDR_MODE_NONE,
        { -1, -1, -1, -1}//{0, 1, 2, 3,}
    }
}

};
有调试过的么，帮助调试下么，可有偿。
