Use ST_Link Programmer from Nucleo 64 F411RE Board to program a Stand Alone STM32F411RE Chips

Hi, I have a ST_Link Programmer that was cut off from STM32F411RE Nucleo 64 Board (zero ohms resistors SB12, 13, 14, and 15 have been also removed). I have been use it to program other STM series Board with no problem.
Currently I am doing a project that is using STM32F411RE Nucleo 64 Board and I have a custom made PCB with STM32F411RE chips on it. I tried to use the same ST_Link Programmer to program the chips by connect the 8 pins from the programmer to the chips, but it does not work. The pins are connected the same as how I connect my programmer to the nucleo board.

I tried to load images here but failed to do it. so I just describe how I connect the pins:

When I connect the programmer to STM32F411RE Nucleo 64 Board:
Programmer- - - - - - - - - - - - - - - - - - - - - - - - - - - - -Board
Left Pin from JP1 (next to USB Power)- - - - - - -VDD (CN7-5)
SWCLK (CN4-2)- - - - - - - - - - - - - - - - - - - - - - - - -PA14 (CN7-15)
GND (CN4-3)- - - - - - - - - - - - - - - - - - - - - - - - - - -GND (CN7-8)
SWDIO (CN4-4)- - - - - - - - - - - - - - - - - - - - - - - - -PA13 (CN7-13)
NRST (CN4-5)- - - - - - - - - - - - - - - - - - - - - - - - - -NRST (CN7-14)
SWO (CN4-6)- - - - - - - - - - - - - - - - - - - - - - - - - - -PB3 (CN10-31)
TX (CN3-1)- - - - - - - - - - - - - - - - - - - - - - - - - - - - -PA3 - RX (CN10-37)
RX (CN3-2)- - - - - - - - - - - - - - - - - - - - - - - - - - - - -PA2 - TX (CN10-35)
With the connection above, I can program my Nucleo board with external ST-Link programmer that I cut off before. Everything works fine.

And then I connected the same programmer to my STM32F411RE Chips with the same pins as following:
Programmer- - - - - - - - - - - - - - - - - - - - - - - - - - - -STM32F411RE MCU
Left Pin from JP1 (next to USB Power)- - - - - - - - - - - -VDD (Pin 19)
SWCLK (CN4-2)- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -PA14 (Pin 49)
GND (CN4-3)- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -VSS (Pin 18)
SWDIO (CN4-4)- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -PA13 (Pin 46)
NRST (CN4-5)- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -NRST (Pin 7)
SWO (CN4-6)- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -PB3 (Pin 55)
TX (CN3-1)- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -PA3 - RX (Pin 17)
RX (CN3-2)- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -PA2 - TX (Pin 16)
This time, when I connect the program to my computer, same storage disk (NODE_F411RE (D:)) has jumped out, however, in stead of usual two files ( DETAILS.TXT and MBED.HTM), there is one additional file called FAIL.TXT, and when I opened it out, it shows: The interface firmware FAILED to reset/halt the target MCU.

I am not sure how to fixed this, if anyone can help, that would be appreciated.
Thank you
