Just received my Netduino mini. I snapped it in a Parallax BOE/usb, installed the latest 4.2 of the .netmf & netduino sdk and tried a small test app, no luck.
The board appears as COM 4 on my laptop. I tried MFDeploy, but no luck. When I'm trying to deploy my test app or trying to ping using MFDeploy, I can see the leds on the BOE flashing but I'm not communicating with the mini.
