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

I did NOT hold or press RESET when I disconnect and reconnect USB cable after S19 is copied. My suspicious is SW1 is broken so that it is always down, does it sound a reasonable guess?

Is the OpenSDA CMSIS-DAP available in the Configuration Dialog as shown here:
