[F4]Using FSMC and FMC together

Hello,

is it possible to use the FSMC (LCD 8080) and the FMC (SDRAM) together on an STM32F4?

I want to drive an SDRAM and an LCD on the same address and data lines. Will there be any problems with this setup?

Review example code for 439 EVAL board, pretty sure that mixes SDRAM, SRAM, NOR, etc

Yes, you re right. The eval board mixes SDRAM and SRAM. I also found an example in the SPL how to use both (SDRAM must be put into idle to use SRAM).
