摄像头驱动 主线DVP与MIPI-CSI2

白嫖: https://github.com/aodzip/sun6i-mipi-csi

MIPI-CSI2 驱动已经测试OV5640摄像头2Lane模式 1080P@15FPS 720P@30FPS
DVP没测试,因为主线本身就支持DVP,希望没给它改坏吧

DVP看git log记录也是南京一个同行搞定的,太佩服牛人了。

请提供更详细的信息:Linux版本,media-ctl所使用的参数,dmesg日志
而且github上的版本比坑网缓存的驱动改动已经很大了,你是从github同步的代码吗?

我是从github下的,我文件系统没安装media-ctl,系统是linux 5.2

请先严格按照github上所指示的环境和初始化方法配置。

这个驱动在编写的时候,是基于
Buildroot环境buildroot 2020.02.1
Linux Kernel版本5.4.35

你先准备一个相同的环境,内核我认为都是5.4版本的就可以接受

环境弄好了,运行media-ctl报

可能是因为摄像头不支持FPS设置,尝试这个指令

Re: 摄像头驱动 主线DVP与MIPI-CSI2

我试了那命令,还是不行,估计是不支持了。我用media-ctl -p打印如下

Device topology
- entity 1: sun6i-csi (1 pad, 1 link)
            type Node subtype V4L flags 0
            device node name /dev/video0
    pad0: Sink
        <- "ov5647 1-0036":0 [ENABLED,IMMUTABLE]

- entity 5: ov5647 1-0036 (1 pad, 1 link)
            type V4L2 subdev subtype Sensor flags 0
            device node name /dev/v4l-subdev0
    pad0: Source
        -> "sun6i-csi":0 [ENABLED,IMMUTABLE]

看了下OV5647在主线的驱动,输出的格式好像只支持MEDIA_BUS_FMT_SBGGR8_1X8
而我5640的DEMO是MEDIA_BUS_FMT_UYVY8_2X8
你可能要自己改很多东西

白嫖: https://github.com/aodzip/sun6i-mipi-csi

MIPI-CSI2 驱动已经测试OV5640摄像头2Lane模式 1080P@15FPS 720P@30FPS
DVP没测试,因为主线本身就支持DVP,希望没给它改坏吧

楼主牛,好像硬件编码也搞定了?
