I am trying to upgrade the firmware on a STM32F407G (Discovery board).
I am already able to run the bootloader on the board (as checked with the st utility to upgrade the firmware using the dfu mode).
Now, I want to create my own app to upgrade the firmware of the device, how can I replicate the functionality of the ST's SW? Any recommendation?
I want to be able to do so, if possible, by connecting the device with the micro-usb port.
Thanks in advance!!
