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

大佬真乃世外高人也！

哇酷小二 · 2020-05-04 08:23:58

也就是说我的V3s MIPI摄像头有救了，楼主真是神人!

拉轰的脚踏车 · 2020-05-04 08:55:39

MIPI摄像头可以用的话， DVP坏了就坏了, 感谢楼主分享啊！

达克罗德 · 2020-05-04 08:59:14

楼主发的东西都超有价值!

牛叉牛叉，看起来楼主好像是从全志 linux 4.9抠出来的代码，值得学习！

难度很大，老外搞了1-2年了，都没搞定！国人厉害！

DVP看git log记录也是南京一个同行搞定的，太佩服牛人了。

厉害了，mipi我一直是裸机下跑

zhenfanhei · 2020-05-04 21:32:01

楼主老厉害了，mipi都搞定了，还乐于分享，就更厉害了，等有空了翻出板子来试一把

AaronHo · 2020-05-05 15:15:33

支持一下大佬！！！
主线内核顶起！！！

yangshuwei · 2020-05-08 00:18:36

大佬，我移植后，运行fswebcam出现以下情况，请是什么问题？我用的摄像头是ov5647

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？

最近编辑记录 aodzip (2020-05-25 16:04:20)

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

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

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

Hello, do I have right dt for ov5640 camera dvp-csi? How can I grab image/video from this camera? What kernel config should I select?
I have media-ctl v4l2. fswebcam and e.t.c.
I tried
fswebcam -r 1920x1080 img.jpg

--- Opening /dev/video0...
Trying source module v4l2...

I tried:
ffmpeg -f v4l2 -framerate 25 -video_size 640x480 -i /dev/video0 output.jpg

What I need to do in order to get some image/video?
How camera is configured from linux to select custom resolution?
I'm using Buildroot 2020.02.01 & linux 5.4.31

您好，我在linux5.2内核上移植了您的 sun6i-mipi-csi ，在内核启动的时候报错：
ov7251: probe of 0-0060 failed with error -2
请问这是什么原因啊？

ookk303 · 2023-06-05 15:00:55

下的官方的5.2内核
放进内核时编译报错多次定义
然后发现这里还有一份 drivers/media/platform/sunxi/sun6i-csi/

bidezhi7777 · 2023-06-24 17:00:23

OV428,也是支持DVP.MIPI~~
