How to swap two memory regions from different banks in FLASH Memory for STM32L475?

Hi,I am working on B-L475E-IOT01A2 which is a STM32L475 series Discovery IoT kit and has an ARM M4 cortex. It has two banks of FLASH Memory of size 512 KB each. I am implementing two applications along with a bootloader and all of them are stored in ...

i work on a project with stm32l010f4 how can i get a regulated stable voltage from one of its output pins?? how can i get VREF as an output for adc?? is there any code for this??

hi every one, i have a question about MDIOS pins in stm32f765zi chip, PA6 and PA10, in the case which we use these pins, Micro is master or slave? because "S" in the name refer to slave, thank u
