I have been experimenting with adding the USB DFU to firmware using the Stm32CubeMX. On both a "black pill" STM32F411 and a home made STM32F405 board, pulling boot0 high during reset, the device will show up as DFU and I can flash new firmware using...

I2C pins are generally - as you point out yourself - configured as open drain, so they don't normally pull the pin high actively. It _is_ possible to use the internal pull up resistor, but those are in the 50 k range, which would be considered a "we...

Ok that does make sense - but I am somewhat baffled why the option is available in stm32cubemx.

I experience exactly the same and also have been unable to find a workaround.
