    Welcome @kishor, to the community!

    There are a myriad of possible scenarios why the STM8 won't work for you without a debugger connected. Without more details on the environmental conditions (schematics, parameters, etc), probably nobody is able to help you.

    For example, pin NRST on the STM8S207 is a bidirectional pin, as you can see from RM0016, section 8. You should therefore look at this pin with an oscilloscope and not just measure a DC voltage with a multimeter.

    Furthermore, for proper work, cleanly created software is necessary - it is certainly not exactly the same as in the other, working boards, is it?
