I have a working example of the SDMMC FATFS demo firmware using HAL version 1.3.2. I want to convert the firmware to use HAL version 1.7.0. However, when I perform the conversion to 1.7.0 the SDMMC no longer works. Any access to the SD card results in a failure. Does anyone have any idea what the problem may be?

They keep reengineering the driver code, watch for new callback methods, and the use of the transceiver.
Make sure you're using memory the core can access directly, for DMA on the SDMMC1 I'm pretty sure you're limited to AXI RAM

@Community member​ Thanks for your reply. I have resolved this problem by porting the SDMMC app from the V170 examples. It appears to be working properly.
