I'm going to develop stm32f4 board for my application but i have no more space so i'm thinking the use of ST-Link V2 utility for program the processor and upgrade the firmware. so is it possible with ST-link v2 utility thru JTAG interface?

On the other hand, consider that anyone with a ST-Link will be able to connect to your product and hack it, load their own firmware and so on.

But that applies to anything that uses an STM32!

You can set the protection to disable SWD/JTAG access, and/or prevent code readout ...
