STM32F446 FatFS Adafruit BSP drivers

Hi! 

I am trying to use an SD card with the STM32F446RE (using Attolic TrueSTUDIO) but I cannot seem to figure out what I am doing wrong. 

I get this error:

FatFS\sd_diskio.h:57:14: error: unknown type name 'Diskio_drvTypeDef'

But in sd_diskio.h file I have already included 'ff_gen_drv.h'. Here is how my sd_diskio.h file looks like:

/* Define to prevent recursive inclusion -------------------------------------*/

#ifndef __SD_DISKIO_H

#define __SD_DISKIO_H

/* Includes ------------------------------------------------------------------*/

#include 'stm32_adafruit_sd.h'

#include 'ff_gen_drv.h'

/* Exported types ------------------------------------------------------------*/

/* Exported constants --------------------------------------------------------*/

/* Exported functions ------------------------------------------------------- */

extern const Diskio_drvTypeDef SD_Driver;

#endif /* __SD_DISKIO_H */

And ff_gen_drv.h file:

/* Define to prevent recursive inclusion -------------------------------------*/

#ifndef __FF_GEN_DRV_H

#define __FF_GEN_DRV_H

#ifdef __cplusplus

extern 'C' {

#endif

/* Includes ------------------------------------------------------------------*/

#include 'sd_diskio.h'

#include 'ff.h'

#include 'stdint.h'

#include 'diskio.h'

/* Exported types ------------------------------------------------------------*/

/**

* @brief Disk IO Driver structure definition

*/

typedef struct

{

DSTATUS (*disk_initialize) (BYTE); /*!< Initialize Disk Drive */

DSTATUS (*disk_status) (BYTE); /*!< Get Disk Status */

DRESULT (*disk_read) (BYTE, BYTE*, DWORD, UINT); /*!< Read Sector(s) */

#if _USE_WRITE == 1

DRESULT (*disk_write) (BYTE, const BYTE*, DWORD, UINT); /*!< Write Sector(s) when _USE_WRITE = 0 */

#endif /* _USE_WRITE == 1 */

#if _USE_IOCTL == 1

DRESULT (*disk_ioctl) (BYTE, BYTE, void*); /*!< I/O control operation when _USE_IOCTL = 1 */

#endif /* _USE_IOCTL == 1 */

}Diskio_drvTypeDef;

/**

*

* @brief Global Disk IO Drivers structure definition

*/

typedef struct

{

uint8_t is_initialized[_VOLUMES];

const Diskio_drvTypeDef *drv[_VOLUMES];

uint8_t lun[_VOLUMES];

volatile uint8_t nbr;

}Disk_drvTypeDef;

/* Exported constants --------------------------------------------------------*/

/* Exported macro ------------------------------------------------------------*/

/* Exported functions ------------------------------------------------------- */

uint8_t FATFS_LinkDriver(const Diskio_drvTypeDef *drv, char *path);

uint8_t FATFS_UnLinkDriver(char *path);

uint8_t FATFS_LinkDriverEx(const Diskio_drvTypeDef *drv, char *path, BYTE lun);

uint8_t FATFS_UnLinkDriverEx(char *path, BYTE lun);

uint8_t FATFS_GetAttachedDriversNbr(void);

#ifdef __cplusplus

}

#endif

#endif /* __FF_GEN_DRV_H */

Anyone has any idea what is going on?

Whoopsie, I think the problem was this line in ff_gen_drv.h:

#include 'sd_diskio.h'

I do however now get in main errors regarding all file functions such as

'undefined reference to `FATFS_LinkDriver''

That sounds like a Linker error - not compiler error?

So that usually means that you haven't included the source or precompiled library which contains the definitions

For FatFs documentation & support, see:

 - in particular, note the 'Resources' section at the end of the page.

Review how this project builds/functions and then port that into the F446 trees

STM32Cube_FW_F4_V1.19.0\Projects\STM32F413ZH-Nucleo\Applications\FatFs\FatFs_uSD

I don't use Atollic, but Keil, I've built and fixed implementations based on the Adafruit SD for the F4, F7 and L4 Nucleos

I have managed to get it working. I used the example told by @Clive One and the FatFs driver provided in the STM32Cube directory. The problem was that I instantiated the FatFS module using CubeMX and for some reason, something wasn't adding up.
