Auto boot cannot be fixed

[kyawkyawlin]

Dear Friends,

My FRDM-K64F cannot boot automatically but with reset button. I followed the following instruction, nothing better.

OpenSDA Serial and Debug Adapter|NXP 

Whenever the OpenSDA Application binary file is pasted into the BOOTLOADER drive, the BOOTLOADER drive disappears after few seconds and LED next to the reset button starts to blink. 

Please help me out. Thank you in advance.

Hi Lin,

You say that the BOOTLOADER disk disappears and the LED start to blink. It's OK. It won't reset by itself. You should unplug USB cable and plug it again without push the reset button. The new debug interface will work.
