Doesn't matter what part you choose. If you have the new image staged in SPI etc all you need is a smaller loader you don't erase to copy and burn the image at boot time. You don't need access to the BOOT pin to do this robustly. You'd want access to the boot pins to give you options in the factory programming scenario
