rk3588调试之imx415摄像头

一、环境

soc：rk3588
sensor：imx415
board: bpi-w3
linux：5.10

二、imx415简介

品牌：SONY
型号：IMX415
接口：MIPI CSI

三、驱动移植

瑞芯微支持的摄像头，有个support list，

此次从该list中选择了IMX415

3.1 驱动源文件及对应脚本

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

3588_linux/3588_linux5.10_v1.0.5/kernel/drivers/media/i2c/imx415.c 3588_linux/3588_linux5.10_v1.0.5/kernel/drivers/media/i2c/Makefile 3588_linux/3588_linux5.10_v1.0.5/kernel/drivers/media/i2c/Kconfig 3588_linux/3588_linux5.10_v1.0.5/kernel/arch/arm64/configs/rockchip_linxu_defconfig

Makefile脚本

obj-$(CONFIG_VIDEO_IMX415) += imx415.o

Kconfig脚本

config VIDEO_IMX415
    tristate "Sony IMX415 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 imx415.

驱动对应的宏开关

CONFIG_VIDEO_IMX415=y

3.2 dts设备树

1）摄像头链接示意图
在这里插入图片描述

IMX415摄像头与SOC连接的主要的引脚有：i2c、rst、pwdn、mclk、MIPI Clk、MIPI DATA

2）电路图
在这里插入图片描述

由电路图可知，几个关键引脚关系：

reset信号：gpio4 A0
power0 down信号：gpio1 B0
I2C通道：3
clock：CLK_MIPI_CAMARAOUT_M3

3）设备树节点

设备树的信息最终转换成i2c_client,并传递给IMX415驱动 imx415_probe(){ compatible = “imx415”;与驱动的 of_match_table 保持一致

rockchip,camera-module-index = <0>;
rockchip,camera-module-facing = "back";
rockchip,camera-module-name = "CMK-OT2022-PX1";
rockchip,camera-module-lens-name = "IR0147-50IRC-8M-F20";

匹配的是external\camera_engine_rkaiq\iqfiles\isp3x下面的iq文件

四、调试技能

4.1 开机log

4.2 查看IMX415设备

驱动加载成功后，会有以下信息

查看摄像头设备节点：

4.3 查看sys文件系统中文件信息

内核会为摄像头在目录/sys/class/video4linux下分配设备信息描述文件

root@linaro-alip:grep imx415 /sys/class/video4linux/v*/name
root@linaro-alip:/rockchip-test# grep imx415 /sys/class/video4linux/v*/name
/sys/class/video4linux/v4l-subdev2/name:m00_b_imx415 3-001a

root@linaro-alip:/rockchip-test# grep "" /sys/class/video4linux/v*/name | grep mainpath
/sys/class/video4linux/video11/name:rkisp_mainpath

4.4 查看拓扑 media-ctl -d /dev/media0 -p

root@linaro-alip:/rockchip-test# media-ctl -d /dev/media0 -p
Media controller API version 5.10.110

从entity 63信息中可以看到：

该Entity完整的名称是：m00_b_imx415 3-001a
它是一个V4L2 subdev(Sub-Device) Sensor
它对应的节点是 /dev/v4l-subdev2，应用程序（如v4l2-ctl）可以打开它，并进行配置
它仅有一个输出（Source）节点，记为pad0
它的输出格式是 [fmt:SGBRG10_1X10/3864x2192@10000/300000 field:none
crop.bounds:(12,16)/3840x2160]，其中SBGGR10是一种mbus-code的简称
它的Source pad0 链接到"rockchip-csi2-dphy0"的pad0，并且当前的状态是 ENABLED。

media-ctl -d /dev/media1 -p
