I cannot seem to program my FRDM-K64F board
I am new to this FRDM-K64F board and mbed. I am trying to program the helloworld example bin to the board. Most of the time I got "SWD ERROR" in fail.txt file. Sometimes the program seems to be running (I see the red LED blinks and no fail.txt file) but the red LED blinks 2 seconds then stops. If I power cycle the board or push the reset button, nothing happens (the red LED doesn't blink.).
Also, I noticed that my board constantly resets by itself (the fail.txt has "TIMEOUT" in it).
Anybody knows anything about this issue?
Thanks in advance,

I had the same issue, got it resolved with update to the latest mbed Interface firmware as described here https://developer.mbed.org/handbook/Firmware-FRDM-K64F. Original FW on the board was from 2014 and probably caused some issues with newer mbed code.
