Sensor list for user space File alpsmediatekcustomcommonhalimgsensorsrcsensorlist.cpp Description Provide the support sensor list to use
14、r space如果内核中当前没有对应的 camera 驱动，需要在以下几个地方增加对应的代码 1)在 alps/mediatek/custom/common/kernel/imgsensor 增加对应的驱动文件夹： 如 hi253_yuv 文件夹,里面包含： hi253yuv_CameraCustomized.h hi253yuv_Camera_Sensor_para.h hi253yuv_Sensor.c hi253yuv_Sensor.h 2)在 alps/mediatek/custom/common/kernel/imgsensor/src/kd_sensorlist.h 添加对应的驱动
15、结构体如添加 hi253 yuv 的结构体：UINT32 HI253_YUV_SensorInit(PSENSOR_FUNCTION_STRUCT *pfFunc);#if defined(HI253_YUV)HI253_SENSOR_ID, SENSOR_DRVNAME_HI253_YUV, HI253_YUV_SensorInit, #endif 3)在 alps/mediatek/custom/common/hal/imgsensor 增加对应的 hal 文件夹如添加 hi253_yuv 文件夹，里面包含： camera_info_hi253_yuv.cpp camera_info_hi253_yuv.h camera_sensor_para_hi253_yuv.h camera_tuning_para_hi253_yuv.cpp cfg_ftbl_hi253_yuv.h /yuv camera 拍照尺寸设置等配置在这边修改 feature_hi253_yuv.cpp 4)在 alps/mediatek/custom/common/hal/imgsensor/src/sensorlist.cpp 添加对应的驱动结构体如添加 hi253 yuv 的结构体#if def
