最近通过原子的视频在学习STM32，今天移植FATFS，去官网下载的最新的FATFS版本为R0.13a，移植过程中发现了与原子视频很多的不同之处，请问各位大大，以及原子大大有没有移植过最新的FATFS？能否给点指导
附件上传一下FATFS-r0.13a吧

这就直接导致了之前的fattester.C中的函数无法使用了。。。。。。

下一个HAL库版本的带FATFS的程序,然后把你下的0.13A的ff.h,ff.c等文件粘贴过去,直接覆盖,然后再拷贝回来就解决了
原子标准库用的是0.10,hal库是0.12,基本上和0.13差不多了,只是ff.h里面的define定义的头都改成FF_了之前是_

呢，我去试试

顶帖，我用0.9的f_mount(0, &fs);能成功。想着升级到最新版，结果
res = f_mount(&fs,"",1);
printf("%d ",res);
错误码13，挂载都是个事儿。
求支援。

IdeaMing · 发表于 2018-2-28 09:33:00

求助分析一下
res = f_mount(&fs,"",1);
printf("%d ",res);
返回值13

经过跟踪代码，发现，[mw_shl_code=c,true]DRESULT disk_read (
BYTE pdrv, /* Physical drive nmuber to identify the drive */
BYTE *buff, /* Data buffer to store read data */
DWORD sector, /* Start sector in LBA */
UINT count /* Number of sectors to read */
)
{
DRESULT res;
int result;

switch (pdrv) {
case DEV_RAM :
// translate the arguments here

result = RAM_disk_read(buff, sector, count);

// translate the reslut code here

return res;

case DEV_MMC :
// translate the arguments here

result = MMC_disk_read(buff, sector, count);

// translate the reslut code here

return res;

case DEV_USB :
// translate the arguments here

result = USB_disk_read(buff, sector, count);

// translate the reslut code here

return res;
}

return RES_PARERR;
}[/mw_shl_code]
上面是原本的，改成下面
[mw_shl_code=applescript,true]DRESULT disk_read (
BYTE pdrv, /* Physical drive nmuber to identify the drive */
BYTE *buff, /* Data buffer to store read data */
DWORD sector, /* Start sector in LBA */
UINT count /* Number of sectors to read */
)
{
DRESULT res;
int result;

switch (pdrv) {
case DEV_RAM :
// translate the arguments here

// result = RAM_disk_read(buff, sector, count);

// translate the reslut code here

return res;

case DEV_MMC :
// translate the arguments here

if(count==1)
      {
            SD_ReadBlock(sector << 9 ,buff2,SECTOR_SIZE);
            memcpy(buff,buff2,SECTOR_SIZE);
      }
      else
      {
            SD_ReadMultiBlocks(sector << 9 ,buff2,SECTOR_SIZE,count);
            memcpy(buff,buff2,SECTOR_SIZE * count);
      }

// translate the reslut code here

return RES_OK;

case DEV_USB :
// translate the arguments here

// result = USB_disk_read(buff, sector, count);

// translate the reslut code here

return res;
}

return RES_PARERR;
}[/mw_shl_code]
并不可行，发现传入的参数是0。
然后索性改成
[mw_shl_code=applescript,true]
DRESULT disk_read (
BYTE pdrv, /* Physical drive nmuber to identify the drive */
BYTE *buff, /* Data buffer to store read data */
DWORD sector, /* Start sector in LBA */
UINT count /* Number of sectors to read */
)
{

      if(count==1)
      {
            SD_ReadBlock(sector << 9 ,buff2,SECTOR_SIZE);
            memcpy(buff,buff2,SECTOR_SIZE);
      }
      else
      {
            SD_ReadMultiBlocks(sector << 9 ,buff2,SECTOR_SIZE,count);
            memcpy(buff,buff2,SECTOR_SIZE * count);
      }
// translate the reslut code here

return RES_OK;
}[/mw_shl_code]
就可以了。现在比较疑惑的是，怎么改这个传入参数。没有看到你说的lun;
