STM32 DFU Multiple Memory IC

Hello,

I have my custom board and it has 3 different memory area (pyhsically) and they are, Internal 64K flash which has 2x32KB sectors, Parallel NOR Flash 64 MBit which has 128KB sector size, 128MBit QSPI Flash which has 64KB sector size.

If i use only internal flash memory, i can easly write and run dfu software referencing st's example.

But i want to write it for all 3 different memory.

What i am looking for is that, when i open ST's DFU PC Software, i need to see all three different memory areas and can upload/download binary to them.

In this document, it is mentioned but i dont understand how to do it. Can anyone guide me with this? What will be the "USBD_DFU_MEDIA Interface" for example?
