Kinetis K22: IAR Workbench with P&E Multilink fails to download code

Hi guys,


I'm trying now for hours to get the P&E Multilink Universal FX to work within IAR for ARM 7.40.

If I use JTAG mode, I always get the message 'Failed to initialize PEMicro interface dll. Session aborted!'. Same same with the onboard OpenSDA-Debugger of the FRDM-K22F board.

Using SWD mode the debugging mode starts, but I have no control. The devices runs automatically and if setting breakpoints I get 'Failed to set breakpoint: Target busy.'



But within Kinetis Design Studio both of the debuggers are working... Has anyone of you a hint, how to get the combination IAR/PEMicro to work?
