High-speed data transfer to memory mapped peripheral using FMC via DMA?

[SBenn.2]

Is it possible to burst transfer a block of data from STM32 internal Flash/SRAM to an external memory mapped peripheral device with an SRAM style interface i.e. Address, Data, CS and R/W using the FMC fed via DMA?

Yes, you can transfer between internal memory and external memory using DMA. Configure FMC so that the external memory is mapped to an address and then set up a memory-to-memory transfer to or from that address.
