PROCESSOR-SDK-J784S4: J784S4-csi2-rx1不能出图

2025-03-11 分类：数字信号处理器 (DSP) & ARM® 微处理器 阅读(153)

Part Number:PROCESSOR-SDK-J784S4

Hi,ti,

    我们自己开发了一个解串板，与J784S4的CSI2-rx1通过demo板背面的接插件连接，摄像头连接在我们的解串板上，其输出是yuv422-8bit & 1280*960，解串板的csi2-tx则是配置为1.5G*4lane，通过在Tda4的psdk增加一个摄像头配置文件，更新到m2_0后，demo板可以正常启动vision_app的multi_cam程序，但是却无法出图。以下是我们的具体信息。

1、在接插件处飞线，测量CSI1_RX_CLK_P，时钟频率为750Mhz，幅值为75mv~339mv，

2、在非连续时钟模式下测量CSI1_RX0_N，幅值从1.3V 到 最小-90多mv。

PSDK中摄像头的配置如下：
static IssSensor_CreateParams  my_130mCreatePrms = {
    SENSOR_OV_MY_130M,       /*sensor name*/
    0x6,                             /*i2cInstId*/
    I2C_ADDR_SENSOR,                /*i2cAddrSensor*/
    I2C_ADDR_SER,                   /*i2cAddrSer*/
    /*IssSensor_Info*/
    {
        {
            MY130M_OUT_WIDTH,               /*width 1280*/
            MY130M_OUT_HEIGHT,            /*height 960*/
            1,                              /*num_exposures*/
            vx_false_e,                     /*line_interleaved*/
            {
                {VX_DF_IMAGE_UYVY, 7},    /*dataFormat and MSB [0]*/
            },
            0,                              /*meta_height_before*/
            0,                             /*meta_height_after*/
        },
        ISS_SENSOR_ACCE130M_FEATURES,     /*features*/
        ALGORITHMS_ISS_AEWB_MODE_NONE,  /*aewbMode*/
        30,                             /*fps*/
        4,                              /*numDataLanes*/
        {1, 2, 3, 4},                   /*dataLanesMap*/
        {0, 0, 0, 0},                   /*dataLanesPolarity*/
        CSIRX_LANE_BAND_SPEED_1350_TO_1500_MBPS, /*csi_laneBandSpeed*/
    },
    12,                                  /*numChan*/
    130,                                /*dccId*/
};

Vivian Gao：

你能确保以下事项得到妥善处理吗？-通道数量和通道极性是否与硬件连接相匹配？-输出车道速度与CSIRX配置匹配-虚拟通道id和数据类型匹配。-最后，输出仅在streamon回调中启动，而不是在此之前。

xiang rong：

we used 4lane to transmit yuv422 ，the speed of lane is " CSIRX_LANE_BAND_SPEED_1350_TO_1500_MBPS" ,

and we start the multi-cam app first  and than start the cam。

Vivian Gao：

Can you make sure to start the camera after calling SET_DPHY_CONFIG? 

,

xiang rong：

hi ti,

    we changed the csi_laneBandSpeed to 800Mbps, than we can capture the 1.3M cam yuv-stream and display it .

,

Vivian Gao：

Okay, we will close this post. If you have any other questions, please post again.
