Posted on November 18, 2017 at 13:32 Good day.
I want to communicate the good news.
After spending a couple of sleepless nights and analyzing the work of the library HAL for working with SDIO + FATFS found to date the only option.
To restore the library functionality, three functions of recording, reading, and CTL must be replaced.
You can take them from the example from the ST in the file cd_diskio.c.
Well, fix the function SD_initialize
DSTATUS SD_initialize(BYTE lun)
{
// return SD_CheckStatus(lun);
Stat = STA_NOINIT;
if(BSP_SD_Init() == MSD_OK)
{
return SD_CheckStatus(lun);
}
return Stat;
}
/**
* @brief Reads Sector(s)
* @param lun : not used
* @param *buff: Data buffer to store read data
* @param sector: Sector address (LBA)
* @param count: Number of sectors to read (1..128)
* @retval DRESULT: Operation result
*/
DRESULT SD_read(BYTE lun, BYTE *buff, DWORD sector, UINT count)
{
DRESULT res = RES_ERROR;
if(BSP_SD_ReadBlocks((uint32_t*)buff,
(uint32_t) (sector),
count, SDMMC_DATATIMEOUT) == MSD_OK)
{
/* wait until the read operation is finished */
while(BSP_SD_GetCardState()!= MSD_OK)
{
}
res = RES_OK;
}
return res;
}
/**
* @brief Writes Sector(s)
* @param lun : not used
* @param *buff: Data to be written
* @param sector: Sector address (LBA)
* @param count: Number of sectors to write (1..128)
* @retval DRESULT: Operation result
*/
#if _USE_WRITE == 1
DRESULT SD_write(BYTE lun, const BYTE *buff, DWORD sector, UINT count)
{
DRESULT res = RES_ERROR;
if(BSP_SD_WriteBlocks((uint32_t*)buff,
(uint32_t)(sector),
count, SDMMC_DATATIMEOUT) == MSD_OK)
{
/* wait until the Write operation is finished */
while(BSP_SD_GetCardState() != MSD_OK)
{
}
res = RES_OK;
}
return res;
}
#endif /* _USE_WRITE == 1 */
/**
* @brief I/O control operation
* @param lun : not used
* @param cmd: Control code
* @param *buff: Buffer to send/receive control data
* @retval DRESULT: Operation result
*/
#if _USE_IOCTL == 1
DRESULT SD_ioctl(BYTE lun, BYTE cmd, void *buff)
{
DRESULT res = RES_ERROR;
BSP_SD_CardInfo CardInfo;
if (Stat & STA_NOINIT) return RES_NOTRDY;
switch (cmd)
{
/* Make sure that no pending write process */
case CTRL_SYNC :
res = RES_OK;
break;
/* Get number of sectors on the disk (DWORD) */
case GET_SECTOR_COUNT :
BSP_SD_GetCardInfo(&CardInfo);
*(DWORD*)buff = CardInfo.LogBlockNbr;
res = RES_OK;
break;
/* Get R/W sector size (WORD) */
case GET_SECTOR_SIZE :
BSP_SD_GetCardInfo(&CardInfo);
*(WORD*)buff = CardInfo.LogBlockSize;
res = RES_OK;
break;
/* Get erase block size in unit of sector (DWORD) */
case GET_BLOCK_SIZE :
BSP_SD_GetCardInfo(&CardInfo);
*(DWORD*)buff = CardInfo.LogBlockSize;
res = RES_OK;
break;
default:
res = RES_PARERR;
}
return res;
}
#endif /* _USE_IOCTL == 1 */
You can fix the file, save it and rewrite it after generation.
And you can make changes to the template and the file will be generated when the project is created.
Dear engineers.
Please correct this problem of the library.
I add a fixed tamplet for the F7 series.
Replacing this file along the way Disk:\Program Files\STMicroelectronics\STM32Cube\STM32CubeMX\db\templates, you will not need to make manual changes after the project is generated in CubeMX 4.1.
Best regards,
George.
