USBDM FRDM-K22 "BDM has no connection to target"

Has anyone used USBDM w/ the FRDM-K22 dev board? I am having issues programming the onboard K22 processor.

I loaded USBDM "OpenSDAv2_1.bin" onto the bootloader. With the default jumper positions I get "BDM has no connection to target" when attempting to do a "detect chip". I can however program the onboard K22 processor by using my FRDM-KL25Z dev board w/ USBDM + a programming cable. Anyone else have a similar issue? Is there some hardware modifications required for programming the onboard processor w/ USBDM SDA?
