    Why it CANNOT acquire device in SWD mode when programming ?


      I design my own PCB board with Psoc 4 BLE chip. And my board is connected with KitProg through five wires,i.e., SWDIO,SWDCLK,RST,GND,VDD. However it happens "There was an error running port acquire: Can not acquire device in SWD mode!",when I plan to program my board. I have checked my board .There seem to be no short circuit and circuit breaker. I don't how to solve this problem. Is there anything wrong with my passive crystal or the Psoc 4 BLE chip. Any help and suggestions will be appreciated.Thanks!
