STM32F4 Bootloader - DFU USB and not DfuSe

Question asked by dev on Feb 17, 2015

the STM32F4 Library has an example for DFU over USB (usbd_dfu.c). However, it is implemented the DfuSe way, so it does not follow the DFU standard and can't be used with software which follows the standard. Does anyone know a source where I can find an standard DFU implementation on-top of the STM32 USB implementation?

It should be part of an bootloader implementation for an actual product which will be shipped to customer. If someone has information about that aswell I would appreciate to hear some experienced words. (How to protect the firmware, how to make the bootloader more failsafe, avoiding device bricking etc.)

Thank you guys.
