Can I use LTDC peripheral for LCD interface and FMC interface to access external Flash at the same time?

Can I use both LTDC peripheral for LCD interface and FMC interface to access external Flash at the same time?

when I'm trying to configure the peripheral "FMC" for NOR flash, LTDC peripheral is disabled.

This may be a pin conflict on a particular STM32 model/package.

If the information given by CubeMX does not make clear what's the conflict, review the pins needed by both peripherals in the given model's datasheet - perhaps print out the Alternative Functions table and use the good old pencil method.

You may need to use a model with more pins, and/or there may be no solution for the given STM32 model.

Lack of pins, or a conflict?

Consider QSPI, uses very few pins, works well.​
