求救：Tina T113-s3（MQ-R） DVP摄像头（OV5640）无法生成/dev/video0设备
-
改了默认串口为uart1，因为uart0占用了csi接口的引脚，显示的错误基本上都没有了，现在就是无法识别到ov5640，OV5640摄像头确认是好的，在正点原子板子上试过的。
板子是mangopi的MQ-R T113-s3。
触摸屏没有问题，都是挂载在twi2上面的：

问个题外的，楼主你的触摸屏的延长线哪里买的

@liefyuan 你的ov5640的驱动都还没有正常加载吧？同时发现你dts中的sensor配置乱七八糟的，官方发布的SDK只需要修改sensor name和I2C配置、供电就可以了。

修改了一下board.dts文件中摄像头设备树：
