I have the same problem with Arduino due, Windows Seven Pro. After I have loaded the "Blink" code, it works fine. I power off the DUE and, then, I power on it. It seems the "Blink" code has not been deleted. The led continues to flash with 1 second period. So I selcted the reset button on the DUE. The led on the DUE stops blinking. But, when I power of and, then, power on the DUE, the led remains on. If I push the reset button nothing happens. If I power of and, then, power on the DUE, nothing happens, the led remain on.
Thread split. Original thread was not about a Due.
The Due has an erase button and a reset button. Which one are you pressing?
