stm32L072 using bootloader and usb dfu when boot0 is connected to ground

[Kprac.1]

Hi,

I am trying to load the bootloader (on a STM32L072) when my main program is running but after reading a lot of posts talking about this subject it seems that it is not possible to start up the bootloader from the main program due to the dual bank boot management( category 5 devices), after multiples tries, I can't get rid of the bank1 booting.

I can't change my design and boot0 is connected to ground.

Does someone have an idea ?

Thanks,

@Kprac.1​   Were you ever able to get this to work? I'm trying to do the same.

I suppose one would need to identify a suitable entry point to the code, or the ​places the tests are done.
