Stm32h7 sdmmc example. This application note provides a comprehensive guide for developers looking to leverage the Secure Digital Multimedia Card (SDMMC) host interface integrated within STMicroelectronics' STM32H7 series microcontrollers. The keys to make it work are: Enable SDMMC in device tree Configure the clock source for SDMMC Format the SD card with MBR partition table and FAT32 file system The SDMMC controller provides a communication interface for the microcontroller to communicate with Multi-Media-Cards, SD memory cards and SDIO devices.

This document describes the SDMMC interaction with other internal peripherals, and presents typical examples that highlight the SDMMC host interface features that facilitate its configuration. This application note describes as an example the SDMMC host interface specific to STM32H743/753 microcontrollers, and explains how to use the module to transfer data from/to SD, MMC and e-MMC memory cards in multiple configurations. I must say that without MDMA, everything works good (I'm aware of cache problems).
