Raspberry Pi Camera Module Causes Reboot

For what it is worth, my R-Pi model B rev 2 with CSI camera seems to work OK with the +5V rail at least as low as 4.2 V as measured on the GPIO pins, although I have not checked in detail. At least it does capture stills, record video, respond over WiFi, and not crash.

I have same problem before.
I modified current_limit_override in /boot/config.txt but no luck.

I tested several USB port power supply
(Raspberry Pi Model B Rev 2.0)(000f)

5V 1A (1000mA) USB port power supply (iPodTouch / iPhone4s) → reboot
5V 2A (2000mA) USB port power supply (iPad2) → reboot
5V 2A (2000mA) USB port power supply (Asus Nexus7) → reboot
5V 2.1A (2100mA) USB port power supply (Apple accessory) → reboot

All of them reboots when trying capture a 10s video(capture a 5sec video is ok though):

I bought new USB port power supply yesterday, a 5V 3A (3000mA) USB port power supply.



It works fine, stream video with VLC also works.



(I didn't add current_limit_override parameter in /boot/config.txt )


Weird, I use a 1A supply and the camera works fine.

I have a similar problem (I think). Loaded everything up, connected camera. Fine and then 10 seconds or so, blue screen. Had to wait 30 mins for the fuses before it would reboot. Worried about connecting camera up again. This seems a similar issue. Tried a mix of cams etc, same problem.
Sometime I think we forget that the Pi has limitations and maybe we've push it too! These sort if problems really shouldn't happen should they?

Well, the camera shouldn't have much effect on the fuse, it's not a USB device, so the only fuse that could fire would be the overall current consumption. BUT, I wouldn't expect the Pi + camera to pull > 750mA at 5v.

Make sure all the connectors are the correct way round, remove all USB devices except keyboard, and try again. I presume you didn't even get to the login prompt?

Or are you talking about a webcam, rather than the Raspi Foundation camera board? In which case, you will be better off with a powered hub.
