Hello @VP.4rabhu​ 

Bootloader version can be retrieved using the bootloader Get Version command.

Please have a look to this AN2606 "Application note STM32 microcontroller system memory boot mode", which  describes the supported peripherals and hardware requirements to be considered when using the bootloader of STM32 devices

The factory delivered boot loader is in ROM/OTP, you don't get to change it.

The interface document describes the protocol it uses along with methods to query the version and supported commands.
