Hi @acassis,
The error in my case was using the micro stm32h7 and i disable the dma, I
don't know if it could be the error he is having.
In the driver of stm32h7/stm32_sdmmc.c there is the following message:
```
* HW Issues when using IDMA
*
* The DMA buffer must be located in a zone accessible via IDMA.
* For SDMMC1, IDMA cannot access SRAM123 or SRAM4. Refer to ST AN5200.
* Buffer validity is checked when CONFIG_ARCH_HAVE_SDIO_PREFLIGHT is set.
*
* MDMA is only available on for SDMMC1 and Not supported at this time.
```
