SD Card Not Working (FR_NOT_READY) on Cube IDE Version 1.12.0

[AA.27]

Hi, I have STM32F413VHT6 board and trying to use FATFS and SDIO card slot, but f_mount returns FR_NOT_READY. i worked in 1 bit mode is working perfectly but SDIO in 4 bit mode f_mount return FR_NOT_READY.i am using below code for both 1 bit and 4 bit mode i am changing the clock divider value 4 to 10 and check clock divider in 96 also 4 bit is not working.

Any ideas what is the issue and how to solve this problem?

You describe a chip not a board.

Check wiring and trace length for socket.

You have pullups on data and command lines?

Debug at DISKIO/SDIO level.​

i received this error

#define HAL_SD_ERROR_REQUEST_NOT_APPLICABLE  SDMMC_ERROR_REQUEST_NOT_APPLICABLE /*!< Error when command request is not applicable         */  

i checked both pullup and no pullup and trace length of the socket also correct.

i am using NUCLEO-F413ZH board. In my SDIO card reader pullup resister available.

i am using 32GB micro SDHC card class 1.This is my SD card reader

Hello @AA.27​ ,

Is your project generated with STM32CubeMX?

If yes, could you please check that the workaround provided in this thread: SDCARD does not work (FR_NOT_READY) when migrating from FW_F4 V1.27.0 to newer FW_F4 V1.27.1.
