I purchased a new FRDM-K64F but MCUxpresso is unable to find it when plugged in via USB. I've updated the bootloader in which now it says "MAINTENANCE" when in bootloader mode. I then updated the additional file (I don't understand what this "additional" file is but the website said to update it) in which it now mounts as DAPLINK. MCUxpresso is still unable to find this board.
Any suggestions as to what I'm doing wrong?
FYI - I trying to get to a point in which I program the MCUxpresso examples via the OpenSDA.
