Hello Gerhard

I would recommend updating FRDM-K22F board OpenSDA firmware to J-Link.

Customer could find and download Segger J-Link firmware from:

https://www.segger.com/opensda.html

Please let us know if there still with issues after update with J-Link firmware.

The problem occurs with Debug_OpenOCD. With Debug_Segger it works.
