return ERROR_NONE; } 3. hal层还有一个地方可以改，作用与所有摄像头 vendor/mediatek/proprietary/custom/mt6735/hal/D2/imgsensor_src/cfg_setting_imgsensor.cpp static SensorOrientation_T const inst = { u4Degree_0 : 90, // main sensor in degree (0, 90, 180, 270) u4Degree_1 : 270, // sub sensor in degree (0, 90, 180, 270) u4Degree_2 : 90, // main2 sensor in degree (0, 90, 180, 270) }; 二、后副摄 1.测试后副摄是否调通[微掌] 1.1 cat /proc/driver/dualcam_brightness // 1 -- 光线强 0 -- 光线弱 有变化说明驱动通了，但是没有虚化效果，是因为上层的宏没配 1.2 上层的宏，临时开关，不能提交: Z:\code5_37_n_base_oule_user\update\alps\system_conf.sh KST_BeautySnap=4 GANGYUN_BOKEH_SUPPORT=yes KST_GANGYUN_BOKEH_SUPPORT=1 KST_OPEN_DOUBLE_CAMERA=yes 1.3 cat /sys/bus/platform/drivers/image_sensor/yuv_shutter // 可以获得亮度值 1.4 查看是否读到id(这里看不到后副摄) cat /proc/driver/camera_info 三、调试方法 1.查看硬件原理图连接--MCLK 经查看v661_bst_k1项目,前后摄连接在同一个MCLK上 2.查看硬件原理图连接--i2c_num 经查看v661_bst_k1项目,前摄连接在i2c总线2上 i2c_num 写在dws中 - 没有写错 四、AF(len)调试 1.对焦框不能变绿(变绿代表对焦ok) 修改alps/vendor/mediatek/proprietary/custom/mt6735/hal/D1/lens/fm50af/lens_para_FM50AF.cpp - 2, // i4AFC_FAIL_CNT + 5, // i4AFC_FAIL_CNT 增大循环次数，改善概率性马达对焦时间长的问题。(四个地方都改) 四一、“自动闪光”亮处也闪 - 减小参数 修改alps\vendor\mediatek\proprietary\custom\mt6735\hal\D2\imgsensor\imx219_mipi_raw\camera_AE_PLineTable_imx219mipiraw.h - 3, //u4StrobeTrigerBV + -10, //u4StrobeTrigerBV -- 共有20多处，全部改过来 五、FlashLight调试 1.hal层代码合入(根据FAE提供)，只需要修改engTab[]，其余不动 alps\vendor\mediatek\proprietary\custom\mt6735\hal\D2\flashlight\flash_tuning_custom_cct.cpp int cust_fillDefaultStrobeNVRam_main (void* data) { int i; NVRAM_CAMERA_STROBE_STRUCT* p; p = (NVRAM_CAMERA_STROBE_STRUCT*)data; static short engTab[]= - {1339,1940,2505,3586,4562,5486,6348,7168,7943,8665,9349,9999}; + #if defined(KST_V618_P300) // 添加宏控，在mk文件中配上：KST_MISC_CUSTOM= KST_V618_P300 + {9633,9872,9999,9292,9450,9815,9757,9282,9667,8884,8969,8962};

- if (sensor_id == 0x90) { + if ((sensor_id == 0x90) || (sensor_id == 0x190)) { 总结 : 主板问题 - 具体是何问题未能找到 案例十三 : 编译报错 - 兼容过多摄像头（最多16个） 平台 : androidN,MTK6737 排查过程: 1. 编译报错log: alps/kernel-3.18/drivers/misc/mediatek/imgsensor/src/mt6580/kd_sensorlist.h:564:5: error: excess elements in array initializer 2.
