基于RK3399 Android11适配OV13850 MIPI摄像头

目录

1、原理图分析

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

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

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

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

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

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

c 复制代码
$(call find-copy-subdir-files,*,$(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。

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
