board: FRDM-K64F
IDE: MCUXpresso
when I press the debug button, it comes an error:
Error in final launch sequence
Error: Unable to configure core for probe index 1.
Wire not connected
LinkServer has been terminated and will be restarted.
Please restart your debug session.
If the problem recurs, please power cycle your debug probe and restart MCUXpresso IDE.

I've updated the bootloader: 0244_k20dx_bootloader_update_0x5000.bin
and the firmware: 0246_k20dx_frdmk64f_0x5000.bin
can't resolve this problem.
please help!
thank you.
