cameras not detected

Post by kivlerton »

Hello,

I'm setting up the StereoPi v2 Camera Kit using the Quick Start Guide and I'm having trouble getting a connection and stream from the cameras. I've only been able to detect 1 using get_camera

Code: Select all

[email protected]tereopi:~# vcgencmd get_camera
supported=2 detected=1
using raspivid -cs the output is

Code: Select all

[email protected]:~# raspivid -cs 0
mmal: mmal_vc_component_enable: failed to enable component: ENOSPC
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

[email protected]:~# raspivid -cs 1
mmal: Cannot read camera info, keeping the defaults for OV5647
mmal: Could not select camera : error 3
mmal: main: Failed to create camera component
mmal: Failed to run camera app. Please check for firmware updates
viewing the gui at stereopi.local there is no video stream but the menu options are there


When using raspistill-v -o test.jpg I get this output

Code: Select all

[email protected]:~# raspistill -v -o test.jpg

When i plug each camera into my Pi0w I get the same mmal error when using raspistill. On the Pi0w, both cameras are detected but cannot take a photo like I can with my raspberry pi camera v2.

Connecting 2 x raspberry Pi camera V2 to the stereoPi gives, Cams detected 0, supported 2 in the camera settings of stereopi.local.

running the raspivid -cs 0 and raspivid -cs 1

Code: Select all

mmal: Cannot read camera info, keeping the defaults for OV5647
mmal: mmal_vc_component_create: failed to create component 'vc.ril.camera' (1:ENOMEM)
mmal: mmal_component_create_core: could not create component 'vc.ril.camera' (1)
mmal: Failed to create camera component
mmal: main: Failed to create camera component
mmal: Camera is not detected. Please check carefully the camera module is installed correctly

Any help would be appreciated, thank you

Hi kivlerton,

According to your error messages I guess the issue is the ribbon cable connection. Please check that cameras are connected correctly.
(btw, it is better to use "raspistill" command but not "raspivid" for tests)

Could you please share a photo of the camera with the ribbon inserted?

As for the Pi0w tests - am I got you right that you can take images using your V2 camera, but can't do this using cameras from the kit? Could you please tell me the OS you are using?

p.s. 'ENOSPC' error usually means two things. It's either lack of GPU memory, or poor connection of one of the line in the ribbon cable.
