Sir

We are not able to program the stm32h725vgt6 board.We got some issues and in order to rectify the issue  we have connected  VDDSMPS and VFBSMPS to the GND and voltage on the VCAP ia about 1V for supply 3.3V V. But still unable to program the board.

Failed to execute MI command:
target remote localhost:61234

Error message from debugger back end:
localhost:61234: Connection timed out.

Is this a custom board? Has the board ever worked?
