STM32H755 FMC SRAM initialization code example needed

[HAL_Allen]

ST moderator: Thread moved from "STM32CubeIDE" forum to "STM32 MCUs Embedded software" forum.

Hello,

I am currently working on STM32H755 (dual-core M7/M4) and trying to use the FMC interface to connect to an external SRAM.

I have checked the STM32CubeH7 firmware package, but I could not find any ready-made FMC SRAM example for STM32H755 (most examples for STM32H745).

I have checked the STM32CubeH7 firmware package,
and it seems that for STM32H745 (and STM32H755) there is only an FMC SDRAM example available,
located under: STM32CubeH7\Projects\STM32H745I-DISCO\Examples\FMC\FMC_SDRAM_DataMemory

Could you please provide:

• An official or working example project for STM32H755 FMC SRAM

• Clarification about which core (M7 or M4) should configure the FMC?

Best regards,
Allen

Hello @HAL_Allen and welcome to the community,

1- You can refer to that example from github: https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Projects/STM32H743I-EVAL/Examples/FMC/FMC_SRAM No official example

Unfortunately, no official example with with STM32H755

2- Both cores can initilize/use FMC.
