Is the QSPI in Memory Mapped mode usable like the FSMC?

Hi there,

I am trying to get my head around the "new" QSPI Interface, because I never used it before. We are trying to figure out if we can use this interface like a FSMC interface in terms of memory mapping.

We are using a third party library which will operate with an external flash memory. The requirement of this library is to just have a "memory address" to work with, the address for the memory is passed to the library and it accesses the memory space like internal space (and has no capabilities to call extra functions or qspi registers).

My question is, is that possible with the QSPI in memory mapped mode, and if so, to what limitations (speed etc.)?

I tried to figure it out with the examples given in the cube package but wasn't able to get a sufficient answer.

Any help is appreciated!

Thank you in advance,

Patrick
