Information about the possibility to upgrade Firmware on STM32

[JDirk.1]

I have heard the ST25DV can be used to upgrade the Firmware of any STM32 Microcontroller. I would like to understand how this is done. Also how the PINs needs to be connected to the STM32. Or is the code transfered via I2C? If so, how does the STM32 know where to place the code? I need general information about this topic. Maybe someone could let me know where to find information (best practices etc.)

many thanks in advance

Baris Yilmaz is talking about, see 1:12 (i cant understand the name, he is talking too fast ...)

Hi,

I think @Baris YILMAZ​ is talking about the fast transfer mode (mailbox) of ST25DV together with SBSFU (acronyms are always hard to understand) of the STM32. I guess you can checkout details in the X-CUBE-SBSFU package.
