How does Quanzhi v853 chip switch sensors on Tina v85x platform?

Purpose

V85x A scheme currently defaults Sensor yes GC2053. If you need to use GC4663（ such as wdr function ） and SC530AI（ Support 500W）, The switching can be completed as follows .

step

Let's say GC4663 For example ,SC530AI Adapt accordingly .

• Step1 Check Sensor Whether the driver is compiled into .ko file
  GC4663 Sensor Driver file gc4663_mipi.c And configuration Sensor Driver compiled Makefile The path of the file path ：
  tina\lichee\linux-4.9\drivers\media\platform\sunxi-vin\modules\sensor
  Modify the configuration Sensor Driver compiled Makefile file ：
  

After adding , again mkernel You can compile GC4663 Driven ko file .

• Step2 Check ISP Whether the effect file has been adapted
  Effect file gc4663_mipi_wdr_default_v853.h route ：
  tina\external\eyesee-mpp\middleware\sun8iw21\media\LIBRARY\libisp\isp_cfg\SENSOR_H\gc4663
  Effect file parsing file isp_ini_parse.c route ：
  tina\external\eyesee-mpp\middleware\sun8iw21\media\LIBRARY\libisp\isp_cfg

If there is no sensor Corresponding effect file , You need to add and adapt .

After adaptation , adopt make menuconfig modify sensor by gc4663.

• Step3 Check board.dts Adapted
  Board level configuration file board.dts The path of ：
  tina\device\config\chips\v853\configs\perf1
  

among ,I2C The address can be from GC4663 Sensor Drive to find .
tina\lichee\linux-4.9\drivers\media\platform\sunxi-vin\modules\sensor\gc4663_mipi.c

• Step4 modify ko Automatically load scripts
  First the ko copy to /lib/modules/ Next , Then load ko.
  （1） Copy ko
  modules.mk The path of ：
  tina\target\allwinner\v853-perf1
  

（2） load ko
S00mpp The path of ：
tina\target\allwinner\v853-perf1\busybox-init-base-files\etc\init.d

• Step5 recompile mpp And firmware

recompile mpp And firmware commands ：

Log in and copy

cleanmpp && mkmpp && mp
