一、背景

全志V821这颗芯片的定位是IPC，所以对摄像头的支持是不会少的

在这里主要以 2lane 的MIPI作为适配

首先登场的是IMX219，这颗摄像头很多人都熟悉，在树莓派、Jetson Nano、OrangePi等开发板都有出现过，现在我们将在FoxPi开发板适配这款摄像头
注：这里使用的SDK为V1.2

二、摄像头参数

2-4 介绍

IMX219 是索尼（Sony）推出的一款 1/4 英寸 CMOS 图像传感器，主要用于移动设备和嵌入式视觉应用。其分辨率为 3280 × 2464（约 800 万像素），支持 MIPI CSI-2 接口，广泛应用于树莓派摄像头模块、无人机、安防监控等领域。

2-5 主要技术参数

  • 分辨率: 3280 × 2464（8MP）
  • 像素尺寸: 1.12 μm × 1.12 μm
  • 传感器尺寸: 1/4 英寸
  • 最大帧率:
    1080p（1920 × 1080）@ 30fps
    720p（1280 × 720）@ 60fps
  • 输出接口: MIPI CSI-2（2/4 Lane）
  • 动态范围: 约 71 dB
  • 功耗: 典型值 225 mW（工作状态）

三、设备树配置

3-1 pio配置

这里使用的是twi0，使用PA3 PA4

c 复制代码 
	twi0_pins_default: twi0@0 {
		pins = "PA3", "PA4";
		function = "twi0";
		bias-pull-up;
		allwinner,drive = <0>;
	};

	twi0_pins_sleep: twi0@1 {
		pins = "PA3", "PA4";
		function = "gpio_in";
	};

使用PA2作为复位引脚

c 复制代码 
	csi_rst_pins_a: csi_rst{
		allwinner,pins = "PA2"; 
	};

3-2 twi0节点配置

c 复制代码 
&twi0 {
	clock-frequency = <100000>;
	pinctrl-0 = <&twi0_pins_default>;
	pinctrl-1 = <&twi0_pins_sleep>;
	pinctrl-names = "default", "sleep";
	/* For stability and backwards compatibility, we recommend setting 'twi_drv_used' to 1 */
	twi_drv_used = <1>;
	status = "okay";

};

3-3 vind0节点配置

注：imx219 器件地址是0x10，这里的twi地址要配置成0x20

c 复制代码 
&vind0 {
	csi_top = <240000000>;
	vind0_clk = <250000000>;
	status = "okay";

	// 	status = "disabled";
	// };

};

四、内核配置

复制代码 
	CONFIG_SUPPORT_ISP_TDM=y
	CONFIG_TDM_ONE_BUFFER=y
	CONFIG_SENSOR_IMX219=y
	CONFIG_SENSOR_IMX219_TWO_LANE_MIPI=y
	# CONFIG_SENSOR_GC1084_MIPI is not set
	# CONFIG_SENSOR_GC05A2 is not set

五、软件包配置

在 openwrt/target/v821/v821-foxpi_ipc/modules.mk添加：

c 复制代码 
#cp sensor imx219 ko to rootfs
define KernelPackage/sensor-imx219
	SUBMENU:=$(VIDEO_MENU)
	TITLE:=Sensor imx219 support (staging)
	DEPENDS:= +kmod-vin-v4l2
	FILES+=$(CONFIG_EXTERNAL_KERNEL_TREE)/bsp/drivers/vin/modules/sensor/imx219.ko
	AUTOLOAD:=$(call AutoProbe,imx219_mipi)
endef

define KernelPackage/sensor-imx219/description
	Kernel modules for sensor-imx219 support
endef

$(eval $(call KernelPackage,sensor-imx219))

让驱动自动打包进文件系统：make menuconfig，搜索imx219，选中 *

修改驱动自动加载脚本
openwrt/target/v821/v821-foxpi_ipc/busybox-init-base-files/etc/init.d/S00mpp

添加：

c 复制代码 
    [ -f $MODULES_DIR/imx219.ko ] && insmod $MODULES_DIR/imx219.ko

六、打包测试
