Hello,I am using a Riverdi RVT101HVSNWC00 board (with STM32H757) for a product that needs a display, interfaces to devices, and writes data to a microSD card. After communicating with Riverdi, I gathered the correct SDMMC1 configuration to make the p...

Hello,I am currently trying to get an Adafruit Feather STM32F405 board to write to files on an SD card using DMA. I'm using CubeIDE, not STM32duino, and I have tried DMA configurations with both a single stream and two streams (one RX and one TX). No...

Thank you! Switching to PLL2R fixed the problem! M4 can now write to the SD card, albeit only at low speed and without MDMA. I may not even need DMA because the system is not transferring very much data.

Using a single DMA stream and adapting the code from here (https://community.st.com/s/question/0D53W00000rXmp7SAC/how-do-i-change-the-direction-of-a-dma-request-for-the-sdmmc-device) to change the DMA direction in the BSP functions makes reading any ...

So far, I've gotten FatFs with SD DMA to work exactly once. I used two DMA streams, one for SDIO_TX and one for SDIO_RX, selected in the IOC editor. I also started using USB for debugging, and I think configuring the clocks to make that work might ha...
