[参考译文] TDA4VEN-Q1：我曾尝试在 TDA4VEN 上安装 OX03F 摄像头、但我不能使用 VISION_APP 显示图像。

您好！

这是您尝试升级的新摄像头吗？ 在其他平台上运行是否正常？ 您进行了哪些更改来启用它？ 您使用的是哪个 SDK 版本？

此致、

Brijesh  

您好！

此摄像头在 UVC 盒上正常亮起。 使用的 SDK 为 ti-processor-sdk-rtos-j722s-evm-09_02_00_05。 我们只是将串行器/解串器配置更改为 max96722和 max96717f、这就是所发生的情况。

尊敬的 Fan：

但是、此摄像头和/或串行器/解串器配置是否已经与其他 TDA4器件一起提供？ 还是想新鲜加电？  

您是否在 CSIRX 中正确配置了通道速度、虚拟通道、数据类型参数、它们是否 与传感器/解串器的输出匹配？  

此致、

Brijesh

您好！

我只想用 vision_app 说明这一点。 我使用的传感器配置具体为1920* 1536、30 fps、数据格式为 raw12。 这是我在驱动程序中的配置。 我不知道有任何其他会阻止 TDA4获取数据的不匹配情况。 此外、我需要在何处配置虚拟通道？

尊敬的 Fan：

虚拟通道 ID 由应用程序设置、就像您使用具有4个摄像头输入的多摄像头示例一样、它 在应用程序中使用虚拟通道 ID 0至3。  

另一个问题是、您在哪里设置 传感器和串行器/解串器配置？ 您是否可以确保在 streamon 回调中进行整个配置？  

此致、

Brijesh

尊敬的 Fan：

我将无法在 Maxim 配置中提供帮助、在这种情况下、您需要与 Maxim 进行检查。  

此致、

Brijesh

您好！

此配置已经过验证、它可以正常亮起、但平台不同。 所以我仍然需要你们的帮助。 谢谢你。

您能否检查此更改？  

此致、

Brijesh

我的 SerDes 在 OX03F_Config 中按如下所示进行配置：其中 ub960配置为 max96722、ub953配置为 max6717f。

static int32_t OX03F_Config(uint32_t chId, void *pSensorHdl, uint32_t sensor_features_requested)

    I2cParams *serCfg = NULL;
    IssSensors_Handle * pSenHandle = (IssSensors_Handle*)pSensorHdl;
    IssSensor_CreateParams * pCreatePrms;

    assert(NULL != pSenHandle);
    pCreatePrms = pSenHandle->createPrms;
    assert(NULL != pCreatePrms);

    if(sensor_features_requested != (sensor_features_requested & ISS_SENSOR_OX03F_FEATURES))
    {
        printf("OX03F_Config : Error. feature set 0x%x is not supported \n", sensor_features_requested);
        return -1;
    }

    ox03fFeaturesEnabled= sensor_features_requested;

    i2cInstId = pCreatePrms->i2cInstId;

    if(ISS_SENSOR_FEATURE_CFG_UC1 == (sensor_features_requested & ISS_SENSOR_FEATURE_CFG_UC1))
    {
        serCfg = ox03fSensorRegConfigWdr60fps.serCfgPreScript;
        sensorCfg = ox03fSensorRegConfigWdr60fps.sensorCfgPreScript;
        sensor_cfg_script_len = OX03F_WDR_CONFIG_SIZE;
    }
    else

            serCfg = ox03fSensorRegConfigLinear.serCfgPreScript;
            sensorCfg = ox03fSensorRegConfigLinear.sensorCfgPreScript;
            sensor_cfg_script_len = OX03F_LINEAR_CONFIG_SIZE;
        }
    }

    /*Deserializer config is done in IssSensor_PowerOn, Need to set sensor alias*/
    status = UB960_SetSensorAlias(chId, OX03F_I2C_ADDR >> 1, pCreatePrms->i2cAddrSer[chId]);
    if(0 != status)
    {
        printf("OX03F_Config Error : UB960_SetSensorAlias for chId %d returned %d \n", chId, status);
    }else
    {
        status = ub953_cfgScript(i2cInstId, pCreatePrms->i2cAddrSer[chId], serCfg);
        if(0 != status)
        {
            printf("OX03F_Config Error : UB953 config failed for camera # %d \n", chId);
        }else
        {
            status = OX03F_Sensor_RegConfig(i2cInstId, pCreatePrms->i2cAddrSensor[chId], sensorCfg, sensor_cfg_script_len);
        }
    }

我仅在 streamOn 函数中打开到0X03F 的流、并读取串行器/解串器的状态寄存器。

        return -1;
    }

            printf("OX03F_StreamOn Error : 60fps mode can support upto 3 cameras because of UB960 b/w limitation \n");
            return -1;
        }
    }

    i2cInstId = pCreatePrms->i2cInstId;
    sensorI2cAddr = pCreatePrms->i2cAddrSensor[chId];

    status |= OX03F_WriteReg(i2cInstId, sensorI2cAddr, 0x0100, 0x1, 1u);/*ACTIVE*/
    appLogWaitMsecs(10);
    status |= enableUB960Streaming(chId);

    status = OX03F_ReadReg(i2cInstId, pCreatePrms->i2cAddrSer[chId], 0x005B, &reg_val, 1U);

    printf("OX03F_StreamOn : 96722 Read: 0x21c=%02x \n", reg_val);

    return (status);
}

好的、我要尝试一下。 但您能告诉我原因是什么吗？

您只需要在 streamon 回调中启动解串器/传感器。 这是需要遵循的序列。  

您好！

我已经将配置过程移至 StreamOn 函数、但仍然显示相同的错误。

您好！

您能否确认配置已从配置回调中删除并仅在 streamon 回调中启用？
