CMSIS-DAP on KL25Z

I'm following instructions on http://www.keil.com/appnotes/files/apnt_232.pdf to update firmware on KL25Z to enable CMSIS-DAP, but failed.

The first 6 steps were exactly the same as described. My in step 7, after connected to PC, the green LED just keeps flashig each second, rather than blink once and then stay on. Checking content on the flash the CMSIS-DAP.S19 was just gone.

Did anyone encountered same problem as me? What happenned and how to make it work?

Thanks - Joey

    Hello

    I tried this today.  I had no problem programming  CMSIS-DAP.S19 into the Freedom board as described.  I used the file from here:  from C:\Keil\ARM\Boards\Freescale\FRDM-KL25Z.
    I used MDK 4.70.

    The only difference from before is:  after cycling the power to the board the green led blinked once for about 1/4 second and went out.

    When I entered Debug mode in uVision (with CMSIS-DAP selected) this led came on until I left Debug mode.
    I will modify the lab with this new information when the DSP fix is confirmed. (will be soon)

    Suspecting a defective Freedom board makes some sense here.

    Thanks
