Does the OS SD card get written to constantly while the camera is running? I had an SD card fail in a weird way and I'm not sure if its Raspberry Pi syndrome or just a bad card.
For reference it's not the card that came with the camera its a Kingston 8gb which is slightly smaller than the original card. To get the Chronos OS onto the card I had to shrink the ROOTFS partition by a little sometime around v0.2 and I have been updating normally since then.
