For diagnostics, there not much exepct does it not now work when previously it did. Worthwhile trying a new SD card image, just to ensure you haven broken the installed software, but apart from that its difficult to tell.theoB610 wrote:Seriously? That's another £25. How do make sure that it is definitely static-ised?
I'm considering buying a webcam instead, it might be a bit more robust.
Always worth reseating all the camera connection, including the connection to the module itself (on the camera PCB)peterpan123 wrote:I reflashed the card, set it all up again, and exactly the same result. When I try to take a photo or video the red light on the camera turns on, and the RPi freezes.
Off to buy a new camera
They don't becomes less sensitive once plugged in....peterpan123 wrote:Good point, but I already tried it.
I guess what worries me is that you still need to be super careful about handling it even once it's all plugged in and running.
Camera not working at all
Example error message: "mmal: mmal_vc_component_create: failed to create component 'vc.ril.camera' (1:ENOMEM)"
Make sure the flex cable is inserted the correct way on both ends, and each connector has the locking tab engaged. The RPi + camera draws about 260 mA more current when recording video, than without the camera. The Model B is about 550 mA by itself, so camera use pushes it over 800 mA. Some power supplies, cables, and polyfuses may not maintain 5V onboard at this current load well enough for reliable operation. You can check this with a voltmeter across TP1 and TP2.
In some cases, the micro-connector from the camera module to the camera board PCB has been loose. This can be fixed by removing and re-seating the small (tiny!) yellow flex cable connector labelled "P5V04A SUNNY" on the camera board. It makes a click when it is fully seated.
There is a very recent firmware update that has a fix for camera startups. It's a really odd bug that's only shown up recently, but has been there a long time. Do a sudo rpi-update to see if it fixes the problem.dlivingstone wrote:Static could be a problem... but from too many hours reading the threads on these forums there is a genuine lack of consistency.
Some folk with multiple cameras and pis are finding that some pi's dont work with some cameras, and other odd issues that are obviously hard to test if you only have one camera and one pi. Its certainly frustrating spending hours trying to fix something when there is no easy way to tell what the problem is. Are there common or typical errors caused by static? Are there any signs or indications that static isn't the problem, and that the camera isn't dead?
I put my camera in a housing as soon as I opened it because I was aware that static was an issue.
It then worked for one day, and stopped working today. Given it was a Christmas present this was a bit disappointing... In trying to fix it I may well have totally borked it now though. Gutted.
Just tapping your foot on the floor generates around 100V -- enough to light a neon bulb. Sparks are only generated at voltages over 300V*, and every centimetre of spark is 33,000 volts. I would guess that most static shocks that we notice must be in that 300-3,000 volt area, since the spark occurs within about a millimetre of the object, although I have certainly experienced one in the centimetre arena. Much less than 300V in the right place will kill electronics.peterpan123 wrote:I certainly wasn't aware of any static discharge, nor have I ever noticed any while at my desk. I'd imagine the amount it takes to destroy a static sensitive chip would be way below the threshold of human perception.
James says not, and he knows best. Also, just connecting it to a RaspPi does not ground it, it just connects it to a bigger circuit-board. Electronics is usually less susceptible when grounded. However RaspPis are often not grounded even when they are connected to a power-supply. Many power-supplies are isolated -- those without earth pins and those with twin core flex for example.I imagined that it was only sensitive to static until it was connected to the board in that once it was connected it was grounded.
