On OSX by using the same FRDM-K22F board and Onboard OpenSDA/J-Link, with KDS 3.2 I can debug w/o problem, but with MCUXpresso 10 I can't. It seems MCUX doesn't provide proper commands to arm-none-eabi-gdb.
I tried the suggestion to delete existing debug configuration and recreate one from Quickstart panel as the following discussion, but it didn't help:
Cannot debug FDRM-K64F via J-link.
See the attachment jlink_setting.png for the debugger setup.
J-Link GDB server connected successfully to the board, and started listening to localhost port 2331.
But arm-none-eabi-gdb didn't send the following command (existed in KDS):
target remote localhost:2331
and as a result MCUX aborts the debugging, shows a misleading message of "Cannot get Jtag device".
Here's the gdb trace:

If I do everything from the command line, by providing "target remote localhost:2331", etc to arm-none-eabi-gdb, debugging is fine.
Also KDS's GDB Client Setup is more flexible than MCUX GDB Client Settings.
KDS has Other options, plus commands, while in MCUX there is no place to enter commands and options.
See kds.png.
Any suggestions how to address this?
Thanks
