I don't know the ride7 toolchain, but the simple internal bootloader can do that.

1) set BOOT0=VCC, BOOT1=GND

2) connect PA9==USART1_TX, PA10==USART1_RX

3) reset the stm32

4) send 0x7F from PC

5) receive ACK from BOOTLOADER

Rest can be read in AN2606.

I guess you needed a little bit different answer:

create such C function in separate file and configure the linker to place the code content of this file into RAM (maybe in RIDE project explorer, maybe by hand-editing the linker file - I don't remember exactly now).

Other compilers use something like __ramfunc or #pragma((__section__ = ''.RAM'')) etc. Please look in the GCC documentation for placing code into RAM, it's there, but well hidden 😉
