Dear all,


I am using KDS 3.2 to write code for KL27 micro-controller. I used P&E's USB-SWD interface for debugging.

I had finished the development and would like to test the power-on behavior.


I tried to use "Flash from file" menu option to write the code (debug code) into the chip. After that, I can see the

code starts executing after I pressed the reset button. This is what I expected.


However I tried to power cycle the board. This time I didn't see the code start running. Had any one experienced this before? Any suggestion. My program will light an LED at the beginning so I can know whether the program starts or not.
