i have a frdm k64f board and it looks nice, but it does not work.
i cant see the device on an ubuntu 14.04 and also i cant see the device on a windows 10.
when i plug in the device a red and a green led are on. when i press a the button int1 the red led goes off. when is press the button reset the redd red is brighter while i press the button. when i do the instruction to flash (reset button before power up) the green led is blinking. but i cant see the drive on the computer. neither on the ubuntu nor on the windows 10.
so what is wrong?
