1、原理图分析

在这里插入图片描述
从上图可看出，我们需要关心的，①MIPI数据和时钟接口使用的是MIPI_TX1/RX1 ②I2C使用的是I2C4总线 ③RST复位引脚使用的是GPIO2_D2 ④PWDN使用的是GPIO1_C7 ⑤MCLK使用的是GPIO3_B7 ⑥需要保证红色框框的供电电源正常。
结合RK提供的文档，如下摄像头数据采集拓扑图所示，我们就可以开始编写配置设备树了，其实官方提供了很多类似的设备树配置给我们参考的。

2、编写和配置设备树

①配置OV13850设备树节点Ⅰ
在这里插入图片描述
②配置OV13850设备树节点Ⅱ 提示：下图复用功能是<. RK_PB7 3 &pcfg_pull_one>;

③配置dphy

④配置isp

3、调试方法

①移植成功后，使用dmesg指令查看对应驱动的log
在这里插入图片描述
②驱动加载成功后，会有生成以下的摄像头设备节点

③RKISP 驱动如果加载成功,会有 video 及 media 设备存在于/dev/目录下。系统中可能存在多个/dev/video 设备,通过/sys 可以查询到 RKISP 注册的 video 节点

④查看拓扑结构
Ⅰ、通过media-ctl -p 查看rkisp1_selfpath 信息，可以知道打开哪些media设备
在这里插入图片描述
Ⅱ、再通过media-ctl -p /dev/media0 查看已打开的media设备的拓扑，下图是截取了一部分信息

⑤查看摄像头支持哪几种图像流格式，截图省略
指令：v4l2-ctl -d /dev/video0 --list-formats
⑥查看调试上层相关信息，截图省略
指令：dumpsys media.camera
⑦抓图
指令：v4l2-ctl -d /dev/video0 --set-fmt-video=width=800,height=600,pixelformat=NV12 --stream-mmap=3 --stream-to=/sdcard/out.yuv --stream-skip=9 --stream-count=1
在这里插入图片描述

查看YUV图片可以使用该网站：在线查看 YUV 文件的免费在线工具 - ImageToStl

4、遇到的问题与解决

①问题1：相机权限问题:解决问题的链接
②问题2：没有获取到对应IQ文件，后面查看编译生成的文件，并没有将IQ文件拷贝过去，报错如下图所示
在这里插入图片描述
解决方法：找到对应IQ目录上的.mk文件，在.mk文件中的PRODUCT_COPY_FILES节点下添加

$(call find-copy-subdir-files,*,$(CUR_PATH)/camera/rkisp1/,$(TARGET_COPY_OUT_VENDOR)/etc/camera/rkisp1/) \

这条语句，这条语句作用是拷贝所有的IQ文件到/vendor/etc/camera/rkisp1/目录下。
③问题3：屏幕显示UI为0度横屏，而默认\hardware\rockchip\camera\etc\camera\camera3_profiles_rk3399.xml文件中配置的是传感器成像方向是90度，导致相机成像出现拉伸现象。
解决方法：如下图所示。
在这里插入图片描述
④问题4：图像上下或者左右相反，可以通过修改OV13850寄存器完成上下或左右的翻转。
解决方法：如下图介绍。

5、补丁
