I have a brand new FRDM-K64F just out of the box, but it keeps resetting every 30 seconds or so.
When I plugged it in, it shows up in Device Manager (Windows 10) as "Portable Devices" -> "MBED" and I can see it as a mass storage device until it resets.
I've gone through the Getting Started steps, but the Out-of-Box "bubble level" demo isn't working.
I've installed the SDK, KDS, and serial drivers. The COM port does appear until it resets.
If I try to load the hello_world example, KDS can't find the device.
Is this a hardware problem or can I do something to recover the board?
