I have an application where it is necessary to read data from external flash to perform operations on data stored in external SRAM by using the same fmc connections. In this case the parallel interface is important as the operations are time sensitive, internal flash and SRAM is not sufficient as i require about 2MB of each.
In a previous application I have, with great success, used the FMC to access multiplexed asynchronous SRAM, I am therefore aware that one has to specify the external memory type in during the FMC setup procedure.
In short, would it be possible to read/write from external flash memory by using the FSMC set-up in SRAM mode or would the configuration have to change each time the memory type changes?
