frdm k64f in bootloader mode

my frdm k64f is always entering the bootloader mode whether or not i press the reset button , whenever i connect it with my laptop it enters the bootloading mode.

Question relating to:

The Freedom-K64F is an ultra-low-cost development platform for Kinetis K64, K63, and K24 MCUs.

Could it be that the RESET pin high? Perhaps due to a shield that you plug on top of the K64F? Try connecting RESET to GND and see if the problem persists. If so, maybe a problem with the RESET button on the board... Try cutting the trace that goes from the button to the RESET pin.
