Need support to use serial monitor in arduino ide or in putty through SWD pins PA13 and PA15 in STM32 Nucleo L152RE Board

SWDIO and SWCLK would facilitate an SWD update method. They would not facilitate a serial port connection, or Arduino Serial Monitor.

You'd perhaps look at using an ST-LINK/V3 pod with a USART.

Or using USB connection of Target MCU and a loader facilitating a CDC Device that appears as a COM Port on the Host PC.​

Check if break-off ST-LINK/V2-1 on the NUCLEO board provides USART via a two pin TX/RX Header​

Ok!
