答案对人有帮助，有参考价值 0 MIPI CSI用法 RK3568平台仅有一个标准物理mipi csi2 dphy,可以工作在full mode 和split mode两个模式, 拆分为csi2_dphy0/csi2_dphy1/csi2_dphy2三个逻辑dphy(参见rk3568.dtsi) 简单点来讲，如果用单目摄像头配置为full mode，若使用双目摄像头配置为split mode Full Mode 仅使用csi2_dphy0,csi2_dphy0与csi2_dphy1/csi2_dphy2互斥,不可同时使用; data lane最大4 lanes; 最大速率2.5Gbps/lane; Split Mode 仅使用csi2_dphy1和csi2_dphy2, 与csi2_dphy0互斥,不可同时使用; csi2_dphy1和csi2_dphy2可同时使用; csi2_dphy1和csi2_dphy2各自的data lane最大是2 lanes; csi2_dphy1对应物理dphy的lane0/lane1; csi2_dphy2对应物理dphy的lane2/lane3; 最大速率2.5Gbps/lane Full Mode设备树配置要点根据板子原理图的MIPI CSI接口找到sensor是挂在哪路I2C总线上，然后在对应的I2C节点配置camera节点，正确配置camera模组的I2C设备地址、引脚等属性。如下ROC-RK3568-PC的xc7160配置： &i2c4 { status = "okay"; gc8034: gc8034@37 { compatible = "galaxycore,gc8034"; status = "disabled"; reg = <0x37>; clocks = <&cru 214>; clock-names = "xvclk"; pinctrl-names = "default"; pinctrl-0 = <&cif_clk>; reset-gpios = <&gpio3 14 1>; pwdn-gpios = <&gpio4 12 1>; rockchip,grf = <&grf>; power-domains = <&power 8>; rockchip,camera-module-index = <0>; rockchip,camera-module-facing = "back"; rockchip,camera-module-name = "RK-CMK-8M-2-v1"; rockchip,camera-module-lens-name = "CK8401"; port { gc8034_out: endpoint { remote-endpoint = <&mipi_in_ucam1>; data-lanes = <1 2 3 4>; }; }; }; }; csi2_dphy0相关配置 csi2_dphy0与csi2_dphy1/csi2_dphy2互斥,不可同时使用。另外需要使能csi2_dphy_hw节点 &csi2_dphy0 { status = "okay"; /* * dphy0 only used for full mode, * full mode and split mode are mutually exclusive / ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; #address-cells = <1>; #size-cells = <0>; ... mipi_in_ucam4: endpoint@5 { reg = <5>; remote-endpoint = <&xc7160_out>; data-lanes = <1 2 3 4>; }; }; port@1 { reg = <1>; #address-cells = <1>; #size-cells = <0>; csidphy_out: endpoint@0 { reg = <0>; remote-endpoint = <&isp0_in>; }; }; }; }; &csi2_dphy_hw { status = "okay"; }; &csi2_dphy1 { status = "disabled"; }; &csi2_dphy2 { status = "disabled"; }; isp相关配置 &rkisp { status = "okay"; }; &rkisp_mmu { status = "okay"; }; &rkisp_vir0 { status = "okay"; port { #address-cells = <1>; #size-cells = <0>; isp0_in: endpoint@0 { reg = <0>; remote-endpoint = <&csidphy_out>; }; }; }; Split Mode设备树配置要点我们需要根据板子原理图的MIPI CSI接口找到两个sensor是挂在哪个I2C总线上，然后在对应的I2C节点配置两个camera节点，正确配置camera模组的I2C设备地址、引脚等属性。如下ROC-RK3568-PC的ov02k10/ov9281配置： &i2c4 { status = "okay";

IQ文件 raw摄像头支持的iq文件路径external/camera_engine_rkaiq/iqfiles/isp21, 与以前不一样的地方是iq文件不再采用.xml的方式，而是采用.json的方式。虽有提供xml转json的工具, 但isp20的xml配置转换后也不适用isp21。若使用raw摄像头sensor，请留意isp21目录所支持的iq文件
