LS1021 TWR CMSIS-DAP / USB-JTAG Getting Started

I'd like to use the USB port as the JTAG on the LS1021A TWR board. It's my understanding that the K20 chip can act as a USB-Serial-to-JTAG bridge. I can't seem to find any documentation on how to do this. Can someone please give me some guidance on:

Getting started?

Jumper settings?

OpenOCD?

GDB setup?

Thank you

Please configure SW2[8] = 0 to enable CMSIS-DAP.

In CodeWarrior, when creating a project, please configure the Connection type as CMSIS-DAP.
