How to flash firmware from an sd card to the board without a bootloader or stm32IDE

[Rlakos]

Hello I am trying to currently flash and install a firmware file that is stored in a SD card in a STM32F746- Discovery board onto the board. I am new at working in this type the project the board its working as a mass storage device using the SD card as the storage and I want to be able to install any firmware files that is stored in the SD card tough an exe app I develop to be able and install it. I heard that using jumper it can be done, does anyone have any idea of how to do it or if anyone know any other way around.

You have to actually write the code to make the magic happen. The ROM based System Loader doesn't provide for this mode of operation. It provides for Serial connectivity, and for USB-DFU mode

See Application Note AN2606
