Camera flash causes reset of the Raspberry Pi 2

This is perhaps the ultimate in non-issues, but it’s worth being aware of all the same.

Peter Onion has found a slight flaw in the Raspberry Pi 2. One of the chips onboard (not the main processor, one of the little ones – shown as a red circle in the image above) causes a crash or reset of the Pi if it gets exposed to a Xenon-powered flash.

The problem can be solved by sticking some electrical tape or blu-tack over the chip while you take the photograph. Or just don’t take the photograph with the Pi turned on. Or use natural light. Really, there are plenty of ways around this, hence why I call it a non-issue. Big thanks and props to Peter for finding it, though 🙂

    Or you could keep the Pi in a case (e.g. Flirc) which will keep the chip covered and in the dark.

    That is not a flaw, it is perfectly normal behaviour of a die on board, photons are creating electrons as it is just the right frequency and intensity so not all light causes will cause this to happen.

      The flaw is that it didn’t have some sort of coating to prevent it. It’s not a flaw per se, though.
