EEPROM需要根据模组厂提供的EEPROM烧录内容和格式说明进行配置，

验证EEPROM

adb shell echo "dumpSensorEEPROMData=1" >> /vendor/etc/camera/camxoverridesettings.txt

该命令执行成功后可以查看/vendor/etc/camera/camxoverridesettings.txt是否生效，然后adb reboot重启设备后打开相机，在/data/vendor/camera/路径下会生成类似文件：

• p24c64e_kbuffer_OTP.txt：从EEPROM中读取的所有数据
• p24c64e_lsc_OTP.txt ：从EEPROM中读取的LSC OTP数据
• p24c64e_wb_OTP.txt：从EEPROM中读取的WBOTP数据

需要确认：

• 读取的数据长度是否与设置的一致？并且大于或者等于烧录内容长度；
• 读取的WB OTP数据是否合法？
• 读取的LSC OTP数据是否合法？尤其注意是否为0或者明显特别大的数据；

WB OTP数据示例：

p24c64e_wb_OTP.txt
Whitebalance data dump for EEPROM p24c64e

Light Type: A 
  rOverG   = 0.828125
  bOverG   = 0.281250
  grOverGB = 0.999023

Light Type: TL84 
  rOverG   = 0.608398
  bOverG   = 0.479492
  grOverGB = 0.999023

Light Type: D65 
  rOverG   = 0.429688
  bOverG   = 0.657227
  grOverGB = 0.999023

LSC OTP数据示例：

multicamera配置

高通Camera会根据
vendor/qcom/proprietary/chi-cdk/oem/qcom/multicamera/chimcxcameraconfig/configs中的配置与DTS中的配置对应然后找到具体加载哪一份配置
netrani/netrani_dc.xml

<Devices

编译

vendor/qcom/proprietary/chi-cdk/oem/Android.mk中指定了编译so文件：

include $(CAMX_CHICDK_OEM_PATH)/qcom/sensor/ov13b10/build/android/Android.mk 

vendor/qcom/proprietary/chi-cdk/configs/product.mk:

PRODUCT_PACKAGES += com.qti.sensor.ov13b10
PRODUCT_PACKAGES += com.qti.sensormodule.united_ov13b10.bin
PRODUCT_PACKAGES += com.qti.tuned.united_ov13b10.bin

vendor/qcom/proprietary/chi-cdk/oem/qcom/buildbins/build/android/binary_parrot会有相应的mk文件，指定了使用哪一个文件来生成：
