Trouble with security flash on KL46Z

Hello Freescale Community! I'm using a FRDM-KL46Z and enabling the security flash option on the "Component Inspector - CPU". Which is the way to download the program on the board?


If I download the program with "Run", CW asks me "Device is secure. Erase to unsecure?" then I click yes and the console say:



INF: Initializing.

INF: Device is Secure.

INF: Device is secured. Erasing ...

INF: Target has been RESET and is active.


But the program never starts running on the board. Somebody knows why?


If I download the program with "Flash File To Target" choosing:


* The correct connection

* Flash configuration file: KL46Z256M4.xml

* The .elf of the program on file to flash


Clicking on "Erase and Program" the program downloads to the board and runs well after pressing the reset button... but when I try the attach option in debug mode, it allows me to debug as if the security flash option is disabled.
