How to use external J-Link Plus with TWRK64F?

I've plugged in the J-Link ARM Cortex-M cable into J5 - K64 JTAG, but the JLink's LED stays Orange, which indicates RESET is asserted, and it cannot access it.


The Getting Started Guide does not indicate any additional steps to configure the board for this.


How can I use an external JTAG with the TWRK64F?


(I've used the J-Link OpenSDA for a while which worked fine, but now it seems to got 'locked' while I was playing with blinky example and I figured I'd try the unlock with the real J-Link).
