There are two kinds of KitProg.
It is KitProg and KitProg2.
These are different things, which are you using?
I'm using the CY*CKIT-042-BLE Pioneer baseboard to flash my custom PCB.
I am using CY8CKIT-042-BLE pioneer kit to flash my board. I'm using jumper wires to connect the SWD pins to my board.

Programming with kitprog requires the Reset pin.
Is the Reset pin connected?
No. It is not. But on the same board I soldered CYBLE-212019 module and it got programmed. Anyways I'll give a try by connecting the reset pin also.
Thanks you were correct. One board just flashed without the reset pin connected and the other dint. I connected the reset pin to kitprog, still it dint work. I removed the pull up resistor connected to the reset pin and it then worked.
