I've been deploying repeatedly to my Netduino for weeks without issue. I've been having a ball with it. Suddenly, my program locked up and the the white LED is only on. The blue LED never blinks. No smoke. I was unintentionally sending 3.3v to a pin setup as an output port. Maybe this fried the board? After no luck, I decided to erase the board. I jumpered the 3.3v pin to the gold square, restated my board. Still only the white LED (which I suppose is expected). Unfortunately, Windows 7 64 does not recognize the device now. So, I'm not able to install the new boot loader. I've tried everything I could on this page: http://wiki.netduino...p.ashx?HL=flash but none of the COM drivers are working for me. Could this be a Win 64 issue? Does someone have an alternative solution? Many thanks in advance! -Will

Hi Will, If you erase your mainboard by applying 3V3 to the ERASE pad, this will clear the application off your Netduino. When the board is erase, both the white and blue LEDs will turn on and stay on. It's the .NET MF firmware which turns off the blue LED after booting. Netduinos are designed to take a bit of abuse, but if your board is erased and only the white LED is turning on when the board is plugged in...the board is most likely damaged. How long have you had your Netduino? Chris P.S. injecting current into a pin which is being used as an OutputPort can cause short circuiting. Especially if the power source is external, the fuse and the diodes on the mainboard can't stop the flow of electrons.
