rv1126适配ov13850摄像头

xinzhiling111

开发板：CORE-1109/1126-JD4核心板及配套的底板
目前进行了一下修改：

1.从维基教程拉下的sdk，/oem/etc/iqfiles/下默认没有ov13850的xml文件，直接从原厂rk3399pro sdk里面拷了一份（原厂rk3399pro开发板及sdk是适配过ov13850的，确认rk3399pro上ov13850可用）。

2.内核配置中打开ov13850驱动。
3.设备树修改如下：
rv1126-firefly-rk809.dtsi文件&i2c1添加如下：（参考rk3399pro设备树里面的配置，并参考rv1126已经适配的os摄像头的配置修改）

32.                         };
    
33.                 };
    
34.         };

上述修改之后，编译内核烧板子进行测试，开机log：

从这个log，认为ov13850驱动已经跑起来了，并且查看板子的/sys目录如下：
[root@RV1126_RV1109:~]# grep ov13850 /sys/class/video4linux/v*/name
/sys/class/video4linux/v4l-subdev3/name:m01_b_ov13850 1-0010

也能看到ov13850, 但是看/dev/目录下有很多video节点，如下：

没找到确定哪个节点的方法，我用rkispp_scale的几个节点试了下，v4l2-ctl拉流的时候都提示select timeout，麻烦了解的大佬给指点一下，少了哪些配置或者如何排查下？多谢

更新：我的硬件接法是，ov13850接到开发版插针上的mipi-csi1上

更新：我的硬件接法是，ov13850接到开发版插针上的mipi-cs1上

怀疑：参考os04a10的设备树上的参数，从它的设备树看，虽然它适配了，但是好像接的是开发版的mipi-csi0，而我适配ov13850接的是mipi-csi1，然后拓扑关系没有进行调整，所以拉不到流？不知道是不是这个原因。看了media的拓扑关系，/dev/media0，开头显示的driver是cif，意思是我的驱动是cif框架不是isp的？

据说ov13850已经停产了，是没人玩这个了吗？萤火虫这论坛也没人管理了吗？

可以抓取视频了，但是明明抓取的是NV12，结果用yuv工具显示一片绿，特别亮的地方能看到不一样的颜色，用YUV420（10bit）能模糊看到拍摄的物品，但是颜色什么的都不对。
