Regarding the bootloader on F4: Use the systembootloader! Set the SYSMEM_MEMRMP
remap bit when the application gets the bootloader request, reset the
core and you enter the bootloader. dfu-util with the -s 0x08000000:leave
argument then will jump to your application after flashing. As force
bootloader pin, use boot 0. The system bootloader also allows to read back
and write to RAM and option byte, all what has yet to be implemented with
our dfu code.
But this only works fot OTG_FS, OTG_HS still needs a custom bootloader...
Bye
