STM32f427 SWD reset issue

On the board is STM32F427ZGT6 with SWD connection used alog with ULINK2 and KEIL 5.1 uVision.

The SWD connection is not recognized withot SWJ checked on, since at reset 32F427 switches to JTAG communication. 

The test program was compiled and successfully programmed in FLASH.  When entering debug mode the stop must be issued, since the processor hangs in strange location.

After manually setting R15 (PC) to 0x0800019c and starting , the code is running.

Why reset button in keil uVision 5.1 is not reseting the target, only stops the target? 

The same code works with Discovery evaluation board without issue.

                 NMI_Handler:
0x08000198 1090      DCW           0x1090
0x0800019A 2000      DCW           0x2000
   175:                  LDR     R0, =SystemInit 
0x0800019C 4808      LDR           r0,[pc,#32]  ; @0x080001C0
   176:                  BLX     R0 
0x0800019E 4780      BLX           r0
   177:                  LDR     R0, =__main 
0x080001A0 4808      LDR           r0,[pc,#32]  ; @0x080001C4
   178:                  BX      R0
