I noticed that the STM32L471x family was omitted from AN2606 describing the STM32 parts with integrated bootloader. The STM32L471 datasheet mentions that there is a bootloader present so I assume this is simply an omission from AN2606? If so is BOOT0=1 the only pin required to enter bootloader mode on reset for this family? The specific part we are using is the STM32L471QEI6. I'm having some trouble getting the bootloader to respond to the initial baud rate initialization 0x7F command.
