I am using the frdm-k22f board with IAR.
If connect J-link to J11 header (SWD Debug) and click Debug button in IAR, it will get error that connection is not possible as follows.

InitTarget (): PCode returned with error code -1.
All H/W connections have been verified.

I do not know what is happening.
