When adding drivers to kdsensorlist and sensorlist, be aware that the sensor adds the same position. Otherwise the driver will run out of chaos, the ISP parameter is not correct, the heavy sensor cannot be started.

2. Photo Image size Settings:

.. \mediatek\custom\prj\hal\camera\camera\cfg_ftbl_$prj$_raw_main.h

Capture Size

Config_feature (Fid_cap_size,

By_default (capture_size_1600_1200),

/*by_default (capture_size_2560_1920), benmodify*/

capture_size_640_480,

CAPTURE_SIZE_1280_960,CAPTURE_SIZE_1600_1200,

)

3.Camera Physical angle Rotation

90 degrees: \alps\mediatek\custom\ $prj $\hal\imgsensor\src\cfg_setting_imgsensor.cpp

static sensororientation_t Const INST = {

U4DEGREE_0:180,//90,//main sensor in degree (0, 90,180, 270)

U4DEGREE_1:0,//90,//Sub sensor in degree (0, 90, 180, 270)

180 degrees:
Sensor Fae provides modification methods.

4.Camera Same Sensor ID compatible (front and rear sensor ID):

Configuration distinction:

Custom_kernel_imgsensor = gc0308_yuv# GC0308_SUB_YUV

Custom_kernel_main_imgsensor =GC0308_YUV # GC0308_SUB_YUV

Custom_hal_imgsensor = gc0308_yuv# GC0308_SUB_YUV

Custom_hal_main_imgsensor = gc0308_yuv# GC0308_SUB_YUV

Kernel: Function names should also be distinguished

\alps\mediatek\custom\common\kernel\imgsensor\gc0308_sub_yuv

\alps\mediatek\custom\common\kernel\imgsensor\gc0308_yuv

Hal: Function names also need to be distinguished

\alps\mediatek\custom\common\hal\imgsensor\gc0308_sub_yuv

\alps\mediatek\custom\common\hal\imgsensor\gc0308_yuv

Kdsensorlist and sensorlist inside add driver also to distinguish, sensor ID do not distinguish, write consistent, according to front and rear camera switch code to differentiate.
