I just made the WIZnet chip on my FEZ Connect shield glow and smoke. :o Unfortunately, I don’t know WHY it decided to do this. Maybe someone has some clues?
I had the FEZ Connect board connected to my Panda II. My Panda II was connected to USB, and I had a 6V power supply connected. I deployed my code, and hit a breakpoint right before calling WIZnet.Enable().
Then I noticed the stream of smoke coming from a nifty little glowing spot on top of the chip.
The only thing that might be weird was that while my Visual Studio was sitting at the breakpoint, I accidentally pressed F5 (run) in a different instance of Visual Studio. So, the 2nd instance of Visual Studio then tried to deploy its code to the Panda II while the 1st instance was already running. Not sure what the implications of that may be.
