Serial Debug link not working

MCUXpresso IDE, TWRK81F150M board.

I'm new to this IDE and board, and though I've set it up according to the quick start, the IDE can't connect to it for debug or console access.


When it is initialized, there's a sample demo app that runs, so I know the serial->usb link is working, but I can't seem to get the demo to quit so I can download, run and debug any new code. I've tried resetting the board for a firmware update, ctrl-c and sending breaks. If there's a jumper that needs to be moved, it's not documented (or not apparent) and though I've read all the startup documentation I can find, they just presume the serial debug link works and that the debugger can talk to the board over the serial link, but I show "device not present".


Anyone familiar with board above or its like who can assist me in getting past the demo?
