FRDM-KL25Z - Cant load precompiled examples

The title might be completely wrong, but I'm going to explain what I can and cant do and hopefully it will make sense.


I plug the board in using the SDA usb port. A virtual com port enumerates as a "OpenSDA - CDC Serial Port" (v1.1.2600.1). I also have v11.1.0.0 of Jungo installed. I dont have the PEMicro OpenSDA Debug Driver installed. A flash drive ("FRDM-KL25Z") appears with a couple of HTML files, some driver info, and a LASTSTAT.txt.

No software seems to be running on the Freescale ARM - no LEDs are flashing.


If I cycle the power holding the reset button, then the green LED flashes, and a flash drive "BOOTLOADER" appears. I copy "DEBUG-APP_Pemicro_v102" into the drive and cycle the power again. I dont get any prompts for the PEMicro OpenSDA Debug Driver.

Going back into BOOTLOADER, I load the "MSD-FRDM-KL25Z_Pemicro_v105" back into the device. Next I go into BOOTLOADER and try copying the *.srec files.


But nothing I do gets the tricoloured LED back up and flashing, or installs the OpenSDA debug drivers.

Am I doing something drastically wrong, and how can I get it back to the world of the living?


I've installed CodeWarrior 10.3 Beta and would desperately like to start some development.
