RK3588 点亮imx586摄像头

学习&笔记2023-09-18 4:09

一.硬件原理图

mipi摄像头硬件确认点：

1.供电：5V，2.8V，1.2V，1.8V，reset脚（硬拉3.3，上电的时候从低到高），pwron脚外接

3.3V。

2,时钟：MCLKOUT是24兆时钟。

3.4组差分mipi线。mipi的data线的波形为方波。

二.驱动移植

RK提供的默认sdk里面已经将支持的所有摄像头驱动都添加到了内核，所以不需要移植该驱动了。

需确认下移植驱动对应的一些信息

源程序

kernel/drivers/media/i2c/imx586.c

kernel/drivers/media/i2c/Makefile

kernel/drivers/media/i2c/Kconfig

kernel/arch/arm64/configs/rockchip_linxu_defconfig

Makefile脚本

obj-$(CONFIG_VIDEO_IMX415) += imx586.o

config VIDEO_IMX586
    tristate "Sony IMX586 sensor support"
    depends on I2C && VIDEO_V4L2 && VIDEO_V4L2_SUBDEV_API
    depends on MEDIA_CAMERA_SUPPORT
    help
      This is a Video4Linux2 sensor driver for the Sony
      IMX415 camera.

      To compile this driver as a module, choose M here: the
      module will be called imx586.

  • 驱动对应的宏开关

    CONFIG_VIDEO_IMX586=y

添加设备树文件：

&i2c5 {
    status = "okay";
    pinctrl-names = "default";
    pinctrl-0 = <&i2c5m0_xfer>;

    imx586: imx586@1a {
		compatible = "sony,imx586";
		reg = <0x10>;  //插摄像头看iic5上出现的新设备后填入
		clocks = <&cru CLK_MIPI_CAMARAOUT_M1>;
		clock-names = "xvclk";
		pinctrl-names = "default";
		pinctrl-0 = <&mipim0_camera3_clk>;//需要和硬件确认是复用的哪个时钟，确认可以量到波形
		power-domains = <&power RK3588_PD_VI>;
		//reset-gpios = <&gpio3 RK_PC7 GPIO_ACTIVE_HIGH>;//现在硬件上是直接拉高，所以不用配
		//avdd-supply = <&vcc_mipidphy0>;//供电也是直接供电，所以不用配
		rockchip,camera-module-index = <0>;
		rockchip,camera-module-facing = "back";
		rockchip,camera-module-name = "default";
		rockchip,camera-module-lens-name = "default";
		port {
			imx586_out0: endpoint {
				remote-endpoint = <&mipidphy0_in_ucam0>;
				data-lanes = <1 2 3 4>;
			};
		};
	};
};

&csi2_dphy0 {
	status = "okay";

	ports {
		#address-cells = <1>;
		#size-cells = <0>;
		port@0 {
			reg = <0>;
			#address-cells = <1>;
			#size-cells = <0>;

			mipidphy0_in_ucam0: endpoint@1 {
				reg = <1>;
				remote-endpoint = <&imx586_out0>;
				data-lanes = <1 2 3 4>;
			};
		};
		port@1 {
			reg = <1>;
			#address-cells = <1>;
			#size-cells = <0>;

			csidphy0_out: endpoint@0 {
				reg = <0>;
				remote-endpoint = <&mipi2_csi2_input>;
			};
		};
	};
};

&csi2_dphy0_hw {
	status = "okay";
};

&mipi2_csi2 {
	status = "okay";

	ports {
		#address-cells = <1>;
		#size-cells = <0>;

		port@0 {
			reg = <0>;
			#address-cells = <1>;
			#size-cells = <0>;

			mipi2_csi2_input: endpoint@1 {
				reg = <1>;
				remote-endpoint = <&csidphy0_out>;
			};
		};

		port@1 {
			reg = <1>;
			#address-cells = <1>;
			#size-cells = <0>;

			mipi2_csi2_output: endpoint@0 {
				reg = <0>;
				remote-endpoint = <&cif_mipi2_in0>;
			};
		};
	};
};

&rkcif {
	status = "okay";
};

&rkcif_mipi_lvds2 {
	status = "okay";

	port {
		cif_mipi2_in0: endpoint {
			remote-endpoint = <&mipi2_csi2_output>;
		};
	};
};

&rkcif_mipi_lvds2_sditf {
	status = "okay";

	port {
		mipi_lvds2_sditf: endpoint {
			remote-endpoint = <&isp0_vir0>;
		};
	};
};

&rkcif_mmu {
	status = "okay";
};

&rkisp_unite {
	status = "okay";
};

&rkisp_unite_mmu {
	status = "okay";
};

&rkisp0_vir0 {
	status = "okay";
 	/* dual isp process image case
 	 * other rkisp hw and virtual nodes should disabled
 	 */
	rockchip,hw = <&rkisp_unite>;
	port {
		#address-cells = <1>;
		#size-cells = <0>;

		isp0_vir0: endpoint@0 {
			reg = <0>;
			remote-endpoint = <&mipi_lvds2_sditf>;
		};
	};
};

三.驱动调试

把驱动代码和设备树文件添加进去后就可以开始调试了。

使用i2ctool工具查看i2c5，发现有2个新的设别：0x10,0x50，猜测其中一个是senser，另一个可能是sensor的马达地址，尝试修改sensor的地址为0x10或者0x50看imx586能不能进probe函数。

当修改imx586的地址为ox10的时候，看imx586已经进了probe函数了。

从log可以看出imx586已经进了probe函数，但是并没有识别到sensor。

这时候，需要确认mipi摄像头上的供电是否正常，时钟是否正常。

经确认是sensor的一路供电没有，供电正常后可以设别到sensor。

到了这一步，可以确认，iic设备已经可以设别到sensor了，并挂载在iic5上面。

四.查看拓扑

m00_b_imx586 5-0010 (1 pad, 1 link）：表示imx586实在mipi0上，挂载在iic5,。

fmt:SRGGB10/4000x3000 表示格式为GB10，分辨率为4000*3000.

拓扑通路为：

m00_b_imx586 -> rockchip-csi2-dphy0 -> rockchip-mipi-csi2 -> stream_cif_mipi_id0 -> video0

五.抓取图像

命令：

v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=BG10 \--stream-mmap=3 \--stream-skip=3 \--stream-to=/tmp/cif888.out \--stream-count=1 \--stream-poll

[  370.297154] mipi2-csi2 ERR1:0x10000000 (ecc2)

发现一直报mipi2-csi2 ERR。

原因：一般报这种错误为物理层解析不到mipi协议。

排查：可能mipi4组差分线出现虚焊假焊，可能mipi插线没有整理好，也可能mipi波形不对。

mipi data波形：为方波
