Hi Wang,
I modified a FRDM-MKE02 board to allow external programming and used this to test the USBDM_SWD_SER_JS16CWJ I have. I was unable to get the programmer to misbehave. This is with a full connection including RST.
So I'm sorry I can't really suggest any way of finding the problem.
If you found it necessary to remove the RST pin then I would suggest that you check the waveform on the RST driver and make sure that it is as expected. There is some debugging information available here:
