Error mounting SD Card in 4-bit mode in stm32f756zg

[dharanik_1399]

Hi,

 

I am encountering an issue with mounting the SD card in 4-bit mode on my STM32F756ZG microcontroller. Despite using the BSP driver (bsp_driver_sd), the SD card fails to initialize and mount correctly, resulting in an initialization error and the FR_NOT_READY_ERROR status.

Thanks&Regards

Hi @dharanik_1399 , I ran into the same problem very recently (on STM32H755). There could be several reasons for the problem you report but I suggest that you check this: https://community.st.com/t5/stm32-mcus-embedded-software/sdcard-with-sdmmc-on-stm32h755zi-nucleo/td-p/770582 .
