6.1 Configure camera sensor hal driver in ProjectConfig.mk

file path device\mediatek\$project\ProjectConfig.mk

example:

CUSTOM_HAL_IMGSENSOR = ov23850_mipi_raw

CUSTOM_HAL_MAIN_IMGSENSOR = ov23850_mipi_raw

6.2 Add camera sensor kernel driver project config (<project>_defconfig)

file path : alps\<kernel>\arch\arm64\configs\<project>_debug_defconfig

example:

–CONFIG_CUSTOM_KERNEL_IMGSENSOR=” ov23850_mipi_raw s5k3m2_mipi_raw s5k5e2ya_mipi_raw imx258_mipi_raw imx377_mipi_raw s5k2x8_mipi_raw CUSTOM_HAL_MAIN_IMGSENSOR = ov23850_mipi“

use menuconfig with console to modify xxx_defconfig

6.3. Add camera sensor kernel driver code to the corresponding path

[By project]

kernel-3.18/drivers/misc/mediatek/mach/mt6755/<project>/ imgsensor/

[By Platform]

kernel-3.18/drivers/misc/mediatek/imgsensor/src/<platform>/

Must modify the corresponding makefile

6.3.1  Add image sensor kernel driver folder

[By project]

kernel-3.18/drivers/misc/mediatek/mach/mt6797/<project>/ imgsensor/Makefile (if it exsit)

Example:

 Add the following items

obj-y += imgsensor/ov23850_mipi_raw/

[By platform]

If the image sensor driver doesn’t exist in the ,Project- directory , build system will proceed to search the driver in {platform} directory. Do not need to modify the makefile.

kernel-3.18\drivers\misc\mediatek\imgsensor\src\<platform>\Makefile .

6.3.2 Add camera sensor kernel driver code to the corresponding path

[By project]

kernel-3.18/drivers/misc/mediatek/mach/mt6797/<project>/ imgsensor/

[By Platform]

kernel-3.18/drivers/misc/mediatek/imgsensor/src/<platform>/

Must modify the corresponding makefile

link you image sensor compiled object

Example: obj-y += ov23850_mipi_raw.o

[By project]

alps/kernel-3.18/drivers/misc/mediatek/mach/mt6755/<project>/ imgsensor/xxxx/Makefile (if it exsit)

[By platform]

alps\<kernel>\drivers\misc\mediatek\imgsensor\src\<platform>\Makefile
