Cannot connect to via FRDM-KL27using blhost

Hi,

My understanding is that the built in ROM contains an image of KBOOT on the FRDM-KL27Z.

My overall goal is to configure the KL27 on the FRDM-KL27Z to boot and UART/I2C flash on the dev board. I am following and adapting the steps listed in MCUBLHOSTUG (blhost User's Guide) and Getting Started with the MCU Flashloader to the KL27 however all attempts to have the KL27 communicate with blhost is unsuccessful.

My procedure is as follows:

1. FRDM-KL27Z is powered thru the SDA USB port (next to SW1) and running an LED color cycling app from internal flash). FOPT is configured via the FlashConfigBlock to:

2. Press and hold SW2 (NMI), then press SW1 (Reset)

3. Release SW1, then release SW2

4. Attempt to connect to the board via blhost.exe. I downloaded the version included with NXP Kinetis Bootloader 2.0.0

syntax:

blhost.exe -p com19 -- get-property 1

Error: Initial ping failure: No response received for ping command.

Any suggestions on what else I can try to connect, or perhaps an explanation as to what I'm missing from my setup would be greatly appreciated.
