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.
This link should be also helpful:

The problem occurs with Debug_OpenOCD. With Debug_Segger it works.
