In the target voltage I can see not detected.
I have removed the ribbon cable and have connected using jumpers now, pins in the following manner:
1 - VDD
7 - SWDIO
9 - SWCLK
3, 6 - GND
I don't know what is going wrong with the ISOL version of the STLINK v2.
Request some assistance on this.
Thanks in advance!

Hello @Makarand !
What tool do you use to connect the STM32?
Try :
1 -> VDD
4 or 6 -> GND
7 -> SWDIO
9 -> SWCLK
To have more information on the ST-Link you can also check the UM1075

Hello @Makarand ,
Please install stm32 cube programmer. For me it's better to try a connection between STM32 and ST-LINK.
Moreover, STM32 Cube programmer allow to program the option byte.

STM32 Cube Programmer not used to debug the product as IAR (Break point etc) but to have an access to the flash memory and cpu with more advanced function, and give some useful information about the ST-link and the MCU target.
Anyway, we will try without it. Did you already program the MCU? If yes did you use low power mode ?
