Too hot, too long delay of VIM3 camera

VIM3
21

You can look in the AIDA64 application, so that there is no doubt about this :slightly_smiling_face:

22

What’s your max frame rate？

哥们，你的最大帧率能达到多少？我一直觉得linux下不大正常，但是android下无论延迟还是帧率都要好多，但是我打算用a311d做工业智能相机，用android会被同行们笑惨的。

23

Since Ubuntu requires active cooling!

24

@Wesley framebuffer下最大是60fps.X11下会慢很多,但是你这个1.多帧率明显是不对的.你设置分辨率是1920x1080,有10多帧的

25

I unplug the power source

I am afraid it will burn

why the sbc is so hot?

26

If this is why you said, the SBC is hot I understand why you panicked about it…

where is your SBC placed ?

27

in my office, the environment temperature is 25C

28

你跑的是20.04 Gnome桌面，这个桌面比较大，占用资源很多，所以是比较烫的，建议加上风扇。

29

怎么转到framebuffer模式？怎么达到60fps？你是在linux下吗？分辨率是3840*2160？

30

谢谢！我可以加一个风扇对着sbc吹，但是有没有推荐的比较轻量级的linux系统？谢谢！

31

There is also an OS Ubuntu server, it will probably be easier for the processor, but it is for certain tasks

32

you need to press ctrl +alt+f1 for entering framebuffer console…
From there you open the Camera, there was an entire thread about it very recently…

33

@Wesley 我的屏幕是1080p的,不是4k的.ctrl+alt+F1可以切换到framebuffer .然后用v4l2_test可以测试这个摄像头

我明白了，你说的是在控制台模式下，测试摄像头。

请问A311D这个芯片稳定吗？你是公司用还是个人使用？

36

Of course better! I think you yourself noticed it
:grin::+1:

37

@WesleyS emmm,我是这个公司的,可以看我后缀,芯片还是稳定的

38

@WesleyS what is the use of VIM3 in your application ?

The processer was pinned due to using Gnome DE, If you need lightweight desktop environment you can use Xfce 4.0, just type the following command

sudo apt install xfce4

18.04 is almost obsolete, only for compatibility reasons it is kept, please use a 20.04 image itself, get the server image and install XFCE4 and use as you wish…

P.S I recommend using the lightDM for lightweight operation…

Thanks a lot!

I don’t need desktop because i just want use a311d to build a industrial intelligent camera for object location or text recognition or bar code or qr and dm decode.

I need a global shutter cmos image sensor which uses mipi-csi interface.

So I bought os08a10 to test the performance of the a311d soc.

Thanks a lot!
