Info : only one transport option; autoselect 'cmsis-dap'
Error: unable to open CMSIS-DAP device
Error: unable to init CMSIS-DAP driver

The problem occurs with Debug_OpenOCD. With Debug_Segger it works.

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.
