Erase memory STM32F415 with STlink/V2

[MDupu]

Can I erase memory of STM32F415 using STlink/V2 - but- without the need to connect all 20 Pins required for full development. If yes what Pins are required - can we use Swim (4 pins) only ?

Understand SWD connections. Minimal connections are GND, SWDIO and SWDCLK. Maybe you can use wire jumpers from the STLINK to your target.

That's what I thought - but was not sure if this would be supported from the STLink with STM32

yes, these 3 signals should be enough to reflash. unless the code running on the MCU has low power clock stop mode or other things which might make activating the debug mode trickier.
