Probably off topic for most people but I thought I'd post this in case it is of interest to some. I picked up one of the new Pi Zero's today, it's basically a stripped down version of the original Pi1, 512MB RAM, 1GHz Broadcom BCM2835 processor, 40 pin GPIO Header, micro USB for power and data etc.
Anyhow I thought I'd give it a try with PilotAware, got enough leads to get it hooked up to everything except a monitor (which isn't usually needed). Initially took the MicroSD card out of one of my working PilotAware units (the second one I put together, based on my original 256MB Pi1, no ARF. Wifi, GPS Dongle and DVB all on a powered USB hub). Unfortunately on applying power there was no sign of the PilotAware hotspot appearing, the only sign of life was the flashing power LED (7 short flashes, then 1 long, then repeats).
Next I tried a clean install with a freshly partitioned and formatted card, installation files copied on to it as usual, put it in the Pi Zero, applied power and left it to do its thing, partition the card, and install the operating system. After 90 minutes there's still no sign of the PilotAware hotspot appearing (usually takes 15 mins or so with the cards I'm using), still getting the same flashing power LED (7 short 1 long, then repeats). When I power down and remove the MicroSD card it still shows 1 big FAT32 partition in GParted, rather than the numerous partitions of a successful PilotAware installation.
A bit of googling seems to indicate that folk using Raspbian have similar issues using old installations, the official Pi Raspbian NOOBS was updated a couple of days ago (to support the new hardware?) so I'm guessing this must be a similar situation. Until my Mini HDMI adapter arrives it's difficult to progress any further, I know the Pi Zero is not on the list of supported hardware, but given its very small form factor, low price, Pi1 architecture and low power consumption (160mA quoted) I'd be interested in anyones suggestions on anything else to try to get it working.
