Note that the ST-Link utility is long obsolete - STM32CubeProgrammer is the current tool.

Is this with the original board, or the "custom" board?

What CubeProgrammer version?

What ST-Link are you using? Is it a genuine ST-Link?

See: How to recognize a genuine ST-LINK/V2 versus a cloned one.

Please show the full log from CubeProgrammer; also a screenshot.

It worked after erasing full chip. But i have a question In my stm32cube programmer whenever i connect my target board its showing the only message like "Ur connection mode is defined with HWrst reset mode .Iam using 2.20.0 stm32cube programmmer version

I put mode: under reset

Please show the actual message.

And a screenshot showing your settings.

You still haven't given any details of the boards you're using.

Show picture of board and ST-LINK.

Show picture of STM32103ZET6 IC that's problematic, large, clear and in-focus if you can manage that.

Details so far suggest you are working with fake/counterfeit parts.
