External NOR Flash access on STM32F407

Hi

I am having trouble in accessing the external NOR flash on STM32F407 device.

As per the user's manual, the FSMCs have been set up but the I doubt whether it's correct or not.

Has anyone tried it before or do ST have some pre configured examples or the initialization files to access this external memory ?

Well I'm not sure there are ''general'' examples, the settings tend to be very board and part specific by their nature.

ST has several ''EVAL'' series board with NOR memories on them, as do Keil, you might want to review those, even ones not explicitly F4, as the function/concept is not inherently that different.

If you want source, I'd suggest you Google specific structures and settings related to FSMC and it's configuration in this context.

ie FSMC_Bank1_NORSRAM2, FSMC_NORSRAMTimingInitTypeDef, FSMC_NORSRAMInit, FSMC_NORSRAMCmd

And, yes I've used and programmed NOR devices.
