using ov5640 with sopine/pine64so baseboard

Recommended Posts

Has anyone gotten the ov5640 camera working with the SOPINE and baseboard?  I'm using a prebuilt image from https://www.armbian.com/download/ - Armbian 5.38 stable Ubuntu 16.04.4 LTS 3.10.107-pine64

I've set camera_type=ov5640 in /boot/armbianEnv.txt and rebooted, but I'm having some trouble loading the camera module:

Here's a link from armbianmonitor diagnostics: http://ix.io/11OU

 

I've attached an image of the sensors I'm trying to use.

 

I originally bought these from the Banana Pi folks for use with the M64, so I thought they should also work with the SOPINE. 

 

Any ideas are appreciated! 

 

Thanks,

Max

There are only contacts on one side of the FFC, so if you plugged them in the wrong way, should still be fine since it's isolated? Did you check if the BPi camera has the same pinout as the Pine64 camera module?

They look the same but reversed... The cables only have contacts on one side, but I thought that it looked like the connector had contacts on both sides. 

 

You're right though. I cut open one of the cables and tested it with a multimeter.  When the contacts on the ribbon are facing up (the wrong way for the connector, the right way for the sopine), there is no connection made.

 

I tried using them in a bpi m64 without any luck, so I though for sure the cameras were dead. I'll have to give that another try.

I looked around for an ov5640 that would work with the sopine/pine64 board connectors but didn't have any luck. Anyone know a place to buy these?

 

Anyway, I bought a "Himax 5 Megapixel Camera Module" from the pine64 store. I tested it out on the pre-built ubuntu desktop legacy image (Armbian_5.38_Pine64_Ubuntu_xenial_default_3.10.107_desktop) and the image quality is pretty good! However, when I try capturing an image on the headless version (Armbian_5.38_Pine64_Ubuntu_xenial_default_3.10.107), the device locks up:

 

pi@pine64:~$ fswebcam  -r 640x480 -p YUV420P  test.jpg

--- Opening /dev/video0...

Trying source module v4l2...

/dev/video0 opened.

No input was specified, using the first.

--- Capturing frame...

Captured frame in 0.00 seconds.

(device locks up here)

 

After cutting the power and booting again, I don't see anything new in the logs.  

 

I've tried this a few times with fresh images, and each time the device seems to lock up when using the headless image. Here are the steps I'm taking:

1. apt-get update && apt-get install fswebcam

2. Edit armbianEnv.txt and set camera_type=s5k4ec

3. Add the following to /etc/modules:

    s5k4ec

    vfe_v4l2

4.  reboot

5.  test the camera: fswebcam  -r 640x480 -p YUV420P  test.jpg

 

I've also tried using this fswebcam fork:  https://github.com/avafinger/fswebcam with the same results.

 

Does anyone have any ideas why this would work on the desktop version, but not the headless version? Or does anyone have any advice on how to debug this better?

After recovering from the April Fools' day, not a complete recovery though, still shaking and panicking when typing in... Here i go...

 

https://www.aliexpress.com/item/OV5640-A28-OV5640-170-degree-wide-angle-lens-500-megapixel-camera-module/32587714258.html?spm=a2g0s.9042311.0.0.bAmW0v

 

beware, it does not work with mmBoard! :lol:

 

Regarding the lock-up, I would suggest double check your DTS (decompile both dtb and do a compare).

Enable VFE debugging messages and recompile.

 

Good luck.

The device trees are identical, but that was a good idea!

 

I used the build system to make a server image and it works fine! I didn't change any kernel settings or add any user patches, so I'm not sure why this one works and the pre-built one doesn't. 

 

Thanks @lex - for the support and the driver for this camera!
