Camera module not detected on Tinkerboard S

Recommended Posts

Posted (edited)

Hi

I've connected a raspberry pi rev1.3 camera module (OV5647) but it cannot be detected. 

On boot I can see the LED diode flash for ~1sec. However none of the usual ffmpeg, fswebcam commands return something.

 

Here's an excerpt from dmesg

linaro@linaro-alip:~/Sandbox$ dmesg | grep ov5647
[    3.278888] ov5647 2-0036: GPIO lookup for consumer enable
[    3.278915] ov5647 2-0036: using device tree for GPIO lookup
[    3.278982] of_get_named_gpiod_flags: parsed 'enable-gpios' property of node '/i2c@ff660000/ov5647@36[0]' - status (0)
[    3.279306] ov5647 2-0036: Failed to detect device

E.g I can see it flash with this command

ffmpeg -f v4l2 -i /dev/video0 -vframes 1 test.jpg

but it also gives me error
 


  libpostproc    55.  3.100 / 55.  3.100
[video4linux2,v4l2 @ 0x808bb5a0] Not a video capture device.
/dev/video0: No such device

Yes I've tried that, and in /boot/config.txt  I see overlay=camera-ov5647-overlay  (writing from memory). Still problem :(.

 

What I did also try was a gstream pipeline, something like this opened up a window. Somehow this bypasses communication, as the Kernel has not detected the camera.

gst-launch v4lsrc ! video/x-raw ! videoconvert ! autovideosink
