How to connect ARM Dev Studio to NXP FRDM-K22F board?

Hi David, I don't have this board to hand, but have used similar. From a quick search, I believe this supports CMSIS-DAP interface.

Go to File > New > Hardware Connection, and search for the MK22FN512VLH12 device on the board (select uninstalled CMSIS-Packs if necessary - pack will be automatically installed in next step)

In the Edit configuration pane, select CMSIS-DAP as the Connection Type pull-down.

Note - I found the below articles whilst searching, which I think you should read before attempting to connect. I recommend you first update your board to ensure latest firmware:
