I was one of the lucky winners of a MKR1000.
I plugged it in the other day and uploaded a simple web server sketch. It worked great. I left it plugged into my PC via USB (for a power supply) and I was checking the status of the web server to see if it was still online.
After around 30 minutes I couldn't connect to the web server and went to investigate. I found that the pc (& laptop) no longer see the Genuino and it no longer runs it's sketch (only proof is I can't connect to it and it's not connecting to my router). Also, the charge light flickers which I don't remember happening when I first plugged it in and uploaded the sketch. I have not plugged a lipo or any other batteries into it, it has only been powered up via usb from my pc.
Any thoughts? I haven't connected any I/O devices and it went from literally working one minute, to seemingly dead the next while sitting there running a sketch. It also only has maybe 1 hour of time being powered up.
For the few moments I got to use it, I have to say, this board really seems amazing.
