香橙派5b 移植 imx415

香橙派5b 移植 imx415

配置设备树

配置 rk3588s-orangepi-5-camera*.dtsi

修改设备树，以 kernel/orange-pi-5.10-rk35xx/arch/arm64/boot/dts/rockchip/rk3588s-orangepi-5-camera3.dtsi 为例，关闭 ov13855 ，添加 imx415 ：

        port {

		#size-cells = <0>;

		isp1_in0: endpoint@0 {
			reg = <0>;
			remote-endpoint = <&mipi1_lvds_sditf>;
		};
	};
};

以此类推，修改三个 dtsi 文件：

配置 rk3588-imx415-c*.dts

再增加三个激活的设备树文件，分别对应香橙派上的三个相机接口：

添加的路径为： kernel/orange-pi-5.10-rk35xx/arch/arm64/boot/dts/rockchip/overlay/rk3588-imx415-c1.dts 。

添加的内容如下：

/dts-v1/;
/plugin/;

/ {
	fragment@0 {
		target = <&csi2_dphy0_hw>;

		__overlay__ {
			status = "okay";
		};
	};

	fragment@1 {
		target = <&csi2_dphy0>;

		__overlay__ {
			status = "okay";
		};
	};

	fragment@2 {
		target = <&mipi2_csi2>;

		__overlay__ {
			status = "okay";
		};
	};

	fragment@3 {
		target = <&rkcif_mipi_lvds2>;

		__overlay__ {
			status = "okay";
		};
	};

	fragment@4 {
		target = <&rkcif_mipi_lvds2_sditf>;

		__overlay__ {
			status = "okay";
		};
	};

	fragment@5 {
		target = <&rkisp0_vir1>;

		__overlay__ {
			status = "okay";
		};
	};

	fragment@6 {
		target = <&i2c7>;

		__overlay__ {
			status = "okay";

			imx415-1@37 {
				status = "okay";
			};
		};
	};

	fragment@7 {
		target = <&rkcif>;

		__overlay__ {
			status = "okay";
		};
	};

	fragment@8 {
		target = <&rkcif_mmu>;

		__overlay__ {
			status = "okay";
		};
	};

	fragment@9 {
		target = <&rkisp0>;

		__overlay__ {
			status = "okay";
		};
	};

	fragment@10 {
		target = <&isp0_mmu>;

		__overlay__ {
			status = "okay";
		};
	};
};

然后在 kernel/orange-pi-5.10-rk35xx/arch/arm64/boot/dts/rockchip/overlay/Makefile 目录下面添加编译：

编译下载dtb文件

然后使用命令重编kernel，会自动将 dts 文件编译，在对应目录下载这四个文件即可：

rk3588s-orangepi-5b.dts 和三个 dtsi 文件在同一目录下。

之所以更新 rk3588s-orangepi-5b.dts ，是因为三个 dtsi 文件是被其调用的，不会单独生成 dtb 。

rk3588s-orangepi-5b.dts 更新到 /boot/dtb/rockchip ：

三个 .dtbo 更新到 /boot/dtb/rockchip/overlay ：

配置板端加载imx415

最后在香橙派上直接输入 sudo orangepi-config ，在 System->Hardware 里空格选择对应在对应camera接口位置加载，回车save然后reboot。

测试camera

测试命令：

gst-launch-1.0 v4l2src device=/dev/video11 ! video/x-raw,format=NV12,width=1920,height=1080, framerate=60/1 ! xvimagesink

iq文件有些问题，颜色有点失真，不过可以正常出图：

问题解决

1. 上电读取不到sensor id

香橙派上读取imx415寄存器报错：

找到报错源头，I2C 通信出错：

最终排查，相机电源引脚及I2C未正常配置，配置完成后，即可正常启动。

使用的imx415芯片两个 SLAMODE 引脚均拉高，因此I2C从机地址为 0x37 ，参照下图：

同时，本电路中复位脚需配置 reset-gpios = <&gpio1 RK_PA6 GPIO_ACTIVE_LOW>; ，应该注意。

最终成功dmesg信息如下：

2. 出图一段时间出现crc/ecc错误

搜索的可能原因如下 ¹：

• 驱动配置的MIPI时钟与sensor输出的MIPI时钟对应不上
• MIPI时序错误，例如SOT的时序不符合MIPI的SPEC
• MIPI信号质量不佳导致的报错

后来发现，在camera1接口可以稳定出图，而2、3接口暂时未发现相关问题。考虑cam2、cam3使用的是时钟4：

而CAM1使用的是时钟3：

可能是相关时钟源导致的，等待进一步验证相关问题。
