Hello, I just bought the FRDM-K64F board a few days ago. I'm using a Windows 7 PC.
I'm following this startup guide: FRDM-K64F|Freedom Development Platform|Kinetis MCUs|NXP
I plugged the board to my PC using a USB. The green light flashes slowly but the RGB LED doesn't turn on when I tilt the board. Why doesn't it turn on?
I went ahead to Step 2 and installed the mbedSerial driver, but I don't see the Com Port show up in Device Manager. What is going on and why is it not working? I need this COM Port # so I can set up Putty. Below is an image showing my Device Manager. It just says "MBED microcontroller USB Device" under Disk drivers but the COM PORT doesn't show up.
