I just received my camera today. Sadly I get no video. I tried the included MicroSD card, then downloaded the latest image and burned it to the original MicroSD card and then a second MicroSD card with the same results. A brief orange flash and then the fan would slowly ramp up to what I assume to be full volume. No video, no USB serial. I connected a FTDI cable to the TTL serial and found that I had a login prompt which lead to a shell.
dmesg provides the following output which leads me to believe my hardware arrived broken. Note at time 1.050212 that a i2c tranfer failed. Note also that due to the 8k length limitation, I had to crop the dmesg output. I think that the device's driver cannot read the video sensor ID and then the rest of the video startup bombs out (no video device).
Can someone confirm my diagnosis and suggest a fix (or explain how to get a replacement unit)?
