HI3559AV100 2Lane*8模式求教

请教一下，HI3559AV100 2Lane*8模式如何配置，需要修改MIPI相关的配置寄存器么，我修改了s32Ret = SAMPLE_COMM_VI_SetMipiHsMode(LANE_DIVIDE_MODE_B);
combo_dev_attr_t MIPI_4lane_CHN0_SENSOR_IMX290_12BIT_2M_NOWDR_ATTR =
{
.devno = 0,
.input_mode = INPUT_MODE_MIPI,
.data_rate = MIPI_DATA_RATE_X1,
.img_rect = {0, 0, 1920, 1080},

{
    .mipi_attr =
    {
        DATA_TYPE_RAW_12BIT,
        HI_MIPI_WDR_MODE_NONE,
        {0, 2, -1, -1, -1, -1, -1, -1}
    }
}

};
IMX290 2Lane模式的驱动在HI3519AV100上已经跑通，HI3559AV100无法获取到MIPI的同步头，示波器测试过MIPI data,MIPI clk,clkin等管脚都是有信号的
