Step1

拿到摄像头厂的驱动代码

param为参数param\hi1333

vnd\vendor\sprd\modules\libcamera\sensor\its_param\qogirl8\Hynix

这里需要注意的是摄像头属于哪个厂商就放在哪个厂商目录

drv为驱动放进

vnd\vendor\sprd\modules\libcamera\sensor\sensor_drv\classic\Hynix\hi1333

Step2

修改

vnd\vendor\sprd\modules\libcamera\sensor\sensor_drv\sensor_lib_cfg.mk

Step3

修改

vnd\device\sprd\qogirl8\ums9360_1h10\module\camera\sensor_config.xml

OTP也在这里加后续再加

Step4

ker\kernel6.6\unisoc\arch\arm64\boot\dts\sprd\ums9360\ums9360-1h10-overlay.dtsi

&i2c1 { status = "okay"; clock-frequency = <400000>; flash_ic: flash-ic@63 { compatible = "sprd,flash-ocp81378"; reg = <0x63>; sprd,flash-ic = <81378>; flash-en-gpios = <&ap_gpio 53 0>; }; sensor_sub: sensor-sub@5a { compatible = "sprd,sensor-sub"; reg = <0x5a>; clock-names = "clk_src","sensor_eb", "clk_96m","clk_64m", "clk_51m2","clk_48m","clk_26m"; clocks = <&mm_clk CLK_SENSOR1>,<&mm_gate CLK_SENSOR1_EN>, <&g14_pll CLK_TGPLL_96M>,<&g14_pll CLK_TGPLL_64M>, <&g14_pll CLK_TGPLL_51M2>,<&g14_pll CLK_TGPLL_48M>,<&ext_26m>; vddio-supply = <&vddcamio>; avdd-gpios = <&ap_gpio 32 0>; dvdd-gpios = <&ap_gpio 144 0>; reset-gpios = <&ap_gpio 137 0>; power-down-gpios = <&ap_gpio 142 0>; sprd,phyid = <2>; csi = <&csi2>; power-domains = <&mm_domain>; }; };

这里主要添加gpio口
