I dug up one of my Netduinos again after several months of absense (we've been moving, and therefore quite busy). I wanted to measure "weatness", so I started by writing a very simple app, just reading input 0, debug.print it, sleep(100) and repeat.
However, it didn't run. The last time I used Netduino I upgraded the firmware on the other one, so I figured I had forgotten to flash this one. A quick check using MFdeploy confirmed that (this one was using RC3).
So I followed the description, and touched the erase-plate and power cycled the netduino. But now the blue light stays on, and my computer does not recognize it anymore. I feel like I've tried everything, but it still won't happen.
What can I do?
