Connecting JTAG debugger to EzSBC2

I have one of these:


... and I plan to use it with Keil MDK and the EzSBC2. The EzSBC2 has SWD (single wire debug) interface, so I need to figure out the connection between the 20-pin JTAG and the EzSBC.

Keil has information on their page about connectors. This info is from there.

I also combined the EzSBC2 schematic and a picture of the board.

UPDATE: Checked and works fine. Pull-up / pull-down resistors were not needed. SWO pin is optional.
