I'm confused about wether STM32L471RG has a USB bootloader or not. AN2606 describes an STM32L47xxx DFU bootloader and that USB DM and USB DP lines should be connected to PA11 and PA12 respectively.
But what confuses me is that no USB FS DM/DP line is described on PA11/12 nor USB capabilities in
STM32L471RG
datasheet.
Solved! Go to Solution.

Hi
gscaglioni
,The STM32L471xx device part numbers are not embedding the USB
, so DFU isn't supported.
The AN2606 application note is generic, with no mention of any details about part numbers.
So user has first to check related product datasheet then check AN26
