bootloader update the application saved on the USB memory stick attached to on STM32F429 Discovery board when reset occurs , it detects if USB flash memory pen is attached, if attached read and copy application file (hexfile) from usb and update

[MAlkh.1]

If reset happens or the board is powered up -> boot loader checks if usb flash memory is attached to the usb port , -> if attached-> check if there is firmware stored in the usb flash memory pen ->is so copy and update the application from usb stick-> then jump to the application which has been updated from the flash memory -> end.

Thanks I really appreciate of you can help me with this thanks.

I think this uses .BIN files, but could be adapted to handle .HEX or .DFU files.
