My MKR1000 connects and disconnects whenever I try to upload or turn on the serial monitor. Usually, I cannot load a program to it. If it successfully load the program, and try to open the serial monitor, that will fail.
Picture below shows the 'blink led' program failing to load, even thought the COM port is found and the board is properly selected. Any ideas? I had this problem right out of the box. Never got it to work.
