Topic: Camera not showing image and hanging web interface

Disabled the video port
Creating callback data...
Creating camera...
Camera Enabled...
Created camera
Target Image Width: 640
Target Image Height: 480
Initialized camera
Created camera: 0.3 Megapixel(video mode,640x480)
Reinitialized.
Preset saved.
Done.

Camera seems to be activating correctly.  However when going to the camera page in the web interface no picture appears and the web interface completely hangs.  I can still access the RPi via SSH, but the web interface is hung with no picture from the camera.  I need to restart the freelss service to start using the web interface again.  But if I try the camera it just reinitializes as it shows above in the CLI but it doesn’t work and doesn’t show any picture.

Any suggestions?

With FreeLSS not running, try to take a picture from the commandline with the command below.

raspistill -o out.jpg

Re: Camera not showing image and hanging web interface

Actually already tried that.  Still doesn't work.  I have ordered a new cable for the camera.  There is a couple very minor kinks, but maybe that's all it takes to break it.  We'll see when I get it.

Re: Camera not showing image and hanging web interface

If raspistill isn't working then the camera or cable is likely bad.  Does typing the following command display any camera related errors?

dmesg

Re: Camera not showing image and hanging web interface

pi@atlas3d ~ $ vcgencmd get_camera
supported=1 detected=1

pi@atlas3d ~ $ raspistill -o out.jpg
mmal: No data received from sensor. Check all connections, including the Sunny one on the camera board

And nothing in dmesg indicating a problem.

The board is detected and initialized.  Just doesn't seem to want to give a picture.

Will the new 8M camera work with FreeLSS?

It really sucks because I haven't even used a scan from this yet.  Just getting around to it now and now it doesn't work!  *grrr*

Re: Camera not showing image and hanging web interface

The most common causes is that the "Sunny" connector has come detached (see photo below) or the ribbon cable is oriented incorrectly.  Reseat the sunny connector by pulling up and then snapping it back into place.  Also, double check that the ribbon cable is facing the correct direction on side that connects to the camera and the side that connects to the Pi.  Remember to de-static yourself by touching a grounded piece of metal before touching the camera because they can be damaged by static electricity.

Re: Camera not showing image and hanging web interface

In my case it appears that the camera sensor was dead.  I have attached a new camera module and it is now working again.
