FatFS on SD card using SDIO in STM32F103

AFink · ‎2023-08-20

Hi,

I'm trying to configure CubeMX to create a FatFS on an SD card using SDIO interface in STM32F103.

I was reading https://community.st.com/t5/stm32-mcus/how-to-create-a-file-system-on-a-sd-card-using-stm32cubeide/ta-p/49830 but it's using SDMMC while I'd like SD card with SDIO.

Is there some tutorial or reading stuff for it?

Thanks for help,

Aviv

The SDMMC peripheral supports both SDIO and MMC (hence the name SDMMC). That tutorial is using SDIO. That's what you want. Specifically, the "SD 4 bits Wide bus" setting selects SDIO, there are other selections for MMC.
