camera 1 cannot show image

Post by GesirenNickZhang »

Hello,

I purchased a StereoPi starter kit. When using the two cameras in the box and running vcgencmd get_camera, I got supported=2 detected=1, so I went ahead to replace the undetected camera with an official Pi cam module.

When I run vcgencmd get_camera gain, it then showed "supported=2 detected=2".

When running raspistill -cs 0, a live video from a camera shows up.

When running raspistill -cs 1, it says:
mmal: mmal_vc_component_enable: failed to enable component: EN0SPC
mmal: camera component couldn't be enabled
mmal: main: Failed to create camera component
mmal: Failed to run camera app. Please check for firmware updates

My OS on the SD card is written from the Raspbian Buster OpenCV Image (Python Code) download on the wiki.

May I receive some help? Thank you for your time.

Edit: The disenabled camera is connected to the port right next to the HDMI port.

Hi GesirenNickZhang,
Can you please check, if system behavior changes if you will swap cameras? Will your disenabled camera work in another CSI connector of the StereoPi?

Hey man,

I went back to my lab today and did more testing. The good camera + ribbon from yesterday was plugged into the CSI port near the HDMI port today and the image came up just fine. I then tried out several camera module + ribbon combinations on the other CSI port and was getting "supported=2 detected=1". The error message for raspistill is OV5647 and could not select camera: error 3.

To me it seems I only have one good camera module and the rest camera modules are both bad (including one from the starter kit). Any thoughts?

thanks,

Hi,

I came back this morning and my thing magically works. Now let's hope it will keep working after I get longer ribbons.

GesirenNickZhang, I don't like magic while making... But I hope it will work for you. :-)

I got a pair of RP HQ cams, while they are both supported and detected, when I run the raspistill -cs command, I got live video from one camera but just black screen from the other (yes I did remove the lens protector). Any idea why this is happening?

thanks

GesirenNickZhang, did you try to swap cameras, and run the same command again?

Hi,

I made a dumb mistake by closing the aperture all the way down :lol: It is all good now

Now I have several hundred MB worth of pictures needed to be exported, and I tried to save them onto my external USB drive but failed - when I drag the pictures into my drive, they refuse to get saved. Is there a way to save them at all?

Thanks

GesirenNickZhang, congrats on finding this iris issue! I got the same with my first HQ camera experiments :-)
As for your USB drive issue - are you able to copy any other files to your drive? I faced a similar issue when the USB drive was removed from Windows incorrectly. In this case, it can be seen as "read-only" by Raspberry OS (and by MacOS too, BTW).
To fix this you can insert it into your Win machine and eject it in the right manner (using the "eject" option).

If this does not help, could you please provide us more details (like the size of your flash drive and the file system type)?

Hi, it made the ready-only go away but gave me the permission error instead. Anyway, I connected the board to the net via ethernet and uploaded my files to one drive so that I open access them elsewhere.
