SDMMC doesn't work in STM32H7A3

Postby mallikarjun_se » Mon Mar 10, 2025 5:16 pm

Hello guys,
I'm trying to use SDMMC on STM32H7A3 but it doesn't seem to work. Anyone else have similar issues with STM32H7A3?
Looking for suggestions.

Regards,

Hi,

What is the malfunction? could it be cache-related? SDMMC is a bus master and the Cortex-M7 cache is not coherent. Other possible issues are clock settings and GPIO settings.
