Missing SDRAM option in STM32CubeIDE for STM32H750VB

Hi, I'm developing a STM32H750VBT6 board that need SDRAM, the datasheet said that only LQFP144 package does not support SDRAM, but I cannot find SDRAM option in FMC configuration. Can someone please help me.Screenshot 2024-07-28 141009.png

Hi,

(i never tried before...but) here on H750V , 

seems little bit "hidden" , only bank2 can be sdram :

I'd be surprised that the 100 pin part exports all the pins needed for SDRAM and the 144 pin doesn't. 

Go through the pin table in the Data Sheet and check manually.

I tried following your configuration but mine donot have Bank Mapping configuration. Can you please a little bit more detail ?

 

No detail - i just have it there. 🙂

Maybe - different H7 packs, i have:

- using still V1.10.0 with MX 6.9.1   -- maybe there something different in version you use.

 

btw

Why you choose sdram on FMC , using up many pins on this 100pin package - and not a quad-spi psram ?

SDRAM is not available on the LQFP100 due to the missing A0, A1 pins (among others).

Contrary to the datasheet, SDRAM is available on the LQFP144 according to CubeMX and my own brief analysis.

@Amel NASRI Can you please look into this?
