that by adding:

If CONFIG_STM32_DFU is defined, the code will not be positioned at the beginning
of FLASH (0x08000000) but will be offset to 0x08003000. This offset is needed
to make space for the DFU loader and 0x08003000 is where the DFU loader expects
to find new applications at boot time. If you need to change that origin for some
other bootloader, you will need to edit the file(s) ld.script.dfu for each
