    Do they?

    I think the bootloaders provided by the chip manufacturers are usually in ROM - not in the user Flash space.

    In the STM32, this bootloader is controlled by the BOOT pins; it loads the code, and then jumps to the reset vector address. This is invisible to the user project.

    I think you are getting confused with writing your own bootloader - which, obviously, does have to start from the reset vector and does have to load the "application" to a different address, and make the jump to the application...?

    For the STM32, ST provide an application note & example of how to do this - search the ST resources for "In-Application Programming" (IAP).
