MEM-to-MEM transfer using DMA (SRAM to FSMC/FMC)

[Zaher]

Hi,

As far as I remember, I've read something about that a while back. I was wondering if I can send data to a memory-mapped device (FSMC/FMC) in a continuous loop a byte per iteration using the DMA peripheral.

Thanks

It should be possible, even when reading from QSPI memory back to internal SRAM.

For graphical displays/frame memory, DMA2D is advised.

Well, it's not for a display. If this is possible, I'd like to see an example.
