Use QSPI Nor Flash in MemoryMappedMode and FMC SDRAM at the same time

LHuaf.1 · ‎2020-10-12

When i used a bootloader to make user program run from QSPI Nor Flash in MemoryMappedMode, it worked well.

But now i want to run user program from FMC SDRAM.

So firstly i plan to initialized both QSPI Nor Flash(MemoryMappedMode) and FMC SDRAM,

then copy program from QSPI Nor Flash to SDRAM with pointer.

But only a little part of data copied.

Does anybody know why?

Hi,

There is no FMC SDRAM on STM32 MPUs (STM32MP15x). I guess you are working with an STM32 MCU.

Please provide your part number reference, then your post could be moved in the right place.
