Hello.
Yesterday I've got the camera. But I have the same issue.
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

Clean latest raspbian, updated, upgraded, rpi-update
Camera enabled in raspi-config
Checked that in /boot/config.txt includes start_file=start_x.elf and fixup_file=fixup_x.dat

I've tested it on several RaspberryPi Version B:
Revision 002
Revision 003
3x Revision 00e
The issue is the same on all boards.
The camera red led does one flash at startup raspberry and one flash when I send the command raspistill -o image.jpg for the first time after reboot. Then it will stay black until next reboot of raspbian.

This is an odd one - not the same as the other errors reported. I'm not sure what can cause failure to connect the preview, and the error code appears invalid. I'll need to look in to it.

Hi all, I'm not sure how helpful this will be, but just in case it helps someone investigate the issues...

My camera works, however, I can make it have the "mmal: mmal_vc_component_create: failed to create...(etc)" errors.

If I just use the camera, fine. If I run servoblaster (the software version, not the kernal version) I then get the mmal... errors that a lot of people are reporting. I can then only fix it by rebooting.
(In case you're wondering, I was trying to make a crude servo based pan/tilt mount for the camera)
Although I don't have a huge knowledge of these things, the fact that starting one app stops another one working, does seem to point to some kind of conflict?

If there's anything anyone would like me to try/give details on, please ask.
Incidentally, the servos were being powered by a completely separate power supply, so I don't think this was a power issue.

ok, the plot really thickens now. I too am trying to build an object tracking system with a pan tilt head, web cam and OpenCV so I have Servoblaster and PiBlaster installed on my machine and I think they load at boot (any idea how to check that?).

If I can work out how to ensure they are not loaded on boot I can see if that makes any difference.

There''s a bug in servoblaster - its using a GPIO that the camera uses. There's a post somewhere describing the required fix in Servoblaster.

Ok, so I was sort of correct that there was a conflict.
So which GPIO pins does the camera need/user i.e. which ones should I avoid using (possibly by other apps)

That could be a defective camera module -either the PCB, the module itself or the cable.
Due to availability of replacement ( sometimes in August (Farnell)) I'm interested in how to sort out where is the problem. I beeped the cable and connections are ok. But on the cable is small visible knick. Can the knick produce this failure ? I can imagine to order somewhere a cable replacement and test it. Is it also possible to test somehow the PCB and fix it ? What is the typical fault with the PCB?

We have no typical faults, it's not been out long enough. I tested by replacing the camera module itself, since I had a spare. The fault moved with the PCB only.

If you buzzed the cable at all lines were OK that won't be the problem.

Great!. I've got it working. I focused on the PCB. I've tried to unplugged and replugged the connection between camera and PBC (the yellow square with sunny written on it). And after that the camera starts working. It must have been there some bad connection between camera and PCB. (Maybe due to shakes or some hit when transporting).
Thanks for help.

Mine had the exact symptoms that cmarty's had and the fix was the same. I had tried just pushing on it before but a couple days ago got it working when I unplugged and then reconnected that connection on the camera board.

I've tried that several times. Even unplug/replug the ribbon cable. I was just messing around with it again hoping that it would magically work. But still no luck. Maybe my camera is a no good. I can send it someone if they want to try it out. better yet, I wish I knew some RPi folks around my neck of the woods. Thanks for offering your ideas.

I think that I managed to remove ServoBlaster and Pi-Blaster last night, I just deleted all the directories associated with the software and did a reboot. Sadly still no joy.

Does anyone know of any tool which will allow me to check the status of the GPIO pins so I can see if any other bits of software have co-opted the ones that camera needs?

The good news is that a package containing the new camera I brought on Wednesday afternoon just arrived on my desk so I will be able to give that a try at the weekend. I've also downloaded the latest Raspian image and will build that on a new SD card as a fresh install in case I still have issues when I connect the new camera.

More to follow at the weekend.

Are you trying with a new SD card image? If after trying that (and remember you still need to update/upgrade with the Feb image), and it still doesn't work, then there may well be a fault with the camera so it will need to be returned.

OK, so could be a dodgy board/sensor.

Checklist:

New SD card image, with update and upgrade run.
Ensure camera is enabled in raspi-config
Check gpu_mem is at least 128, and firmware used is start_x.elf (both in config.txt)
Check all ribbon cable connections are solid and the right way round
Check the camera is actually firmly attached to the PCB (in fact, unplug, blow out any fluff and reseat)

If all of that doesnt fix it, then it may be faulty.

heh - that was my problem.

My camera had failed after I moved the pi ( without even touching the camera ribbon cable ).

I found that the connector was not actually plugged in, it was just resting on the on the receptacle, so it was just luck that the camera ever worked. I was able to lift the connector away from the pcb with no force at all, I then pushed it down on to the board and it located with an audible click.
Camera is now working as expected.

Perhaps there is a case for a sticky for camera related problems.

Hi Jamesh,

Yesterday I received my camera and I got it working pretty quick.
Now I'm having the problem that the red light on the camera turns on when I use the 'raspistill -o test.jpg' command. I can keep waiting but nothing happens until I reboot. All I did yesterday is adding the samba package and connecting a usbdrive with external power to store the images on.

I've done all the things in your checklist and worked with a fresh SD card.
Complete reinstall, update, upgrade, config and reconnecting the camera and reconnecting the 'sunny' connector.

Nothing helps. Again: still image or video -> results in a freeze and permanent red light on the camera.

Any other ideas? I only had 1 day of fun with it... :(

My camera module was shipped in it's "little white box" stuffed into a bubble envelope.

Apparently, the parcel service Newark uses in the US runs all it's envelopes through a set of rollers (joking) because the box was smashed flat (and the mylar flex circuit was crimped rather sharply) (not joking).

In any case, I got these messages as well, and as it turned out all the mashing in the mail caused the flex circuit connector to become dislodged - the camera module was in place, but it was essentially unplugged from the board.

This wasn't really evident until I looked at it really closely, so if anyone is having trouble getting their camera recognized, they should definitely check this connector.

After I got everything working, it seems as if my camera is awful grainy, even with a reasonable amount of light - I'm wondering if the connector got damaged. Does anyone know if there any way to get the camera to produce a test pattern that would allow for validation of the data path?
