I'm still trying to figure this out and, based on documents like Sensor board demo with FRDM-K64 I've tried disconnecting everything except the freedom board and clicking on the "Blue Bug" to find the debug port but get:
I'm guessing I'm not setting something correctly or haven't installed something, but for the life, of me, I have no idea what it is.
Anybody have any ideas?

Success!
The problem was that I wasn't updating the Freedom boards with the correct firmware.
After quite a bit of searching and trying, I found Getting Started with MCUXpresso SDK (which I had previous dismissed because there wasn't "IDE" in the title) and on Page 73 (Appendix C - Updating Device Firmware) there are links on where to go (for SEGGER J-Link, PEmicro OpenSDA and CMSIS-DAP).
Don't bother with PEmicro or CMSIS-DAP, go straight to SEGGER J-Link. I had tried and retried PEmicro because in the "Debug Configuarions" Window of MCUXpresso IDE, if you select PEmicro, there is an OpenSDA option - after trying to download the PEmicro firmware into the Freedom Board (which seems to work normally), I saw that the "MAINTENANCE" folder kept coming up when I plugged in the Freedom board.
The SEGGER pages are somewhat confusing. May I suggest that you go directly to:
- Look for "Compatible Evaluation Boards" to find the OpenSDA that is correct for your Freedom board. Once you have figured out which one you want, go to:
- Look for "J-Link OpenSDA - Generic Firmwares" and click on "Click for Downloads" to get the menu of different versions of OpenSDA which should match what's required by your Freedom board.
Once you have the firmware, then press the reset button on your Freedom board and plug it into a (Windows or Linux) PC's USB port, where it comes up as "MAINTENANCE" and drag in the downloaded firmware.
Then, when you want to debug a board, you get:
If this is explained anywhere (and I just couldn't find it), please "Reply" with the link.
