I have dumped flash with openocd and compared different parts (vector table / firmware / main code). And all of them look fine - vector tables and main code kept intact and only firmware part differs after DFU update. So, everything as expected. But still controlled doesn't boot with updated firmware.
main code is pretty simple and just turns the LED if it starts, but it doesn't...

int main(void)
