stm32 SDIO 操作的寄存器版本，是根据库函数版本改的，不支持多块写入，貌似是库函数原有的bug，暂时没法解决。使用时依次调用SD_Init()，SD_GetCardInfo(&SDCardInfo)，SD_SelectDeselect((u32) (SDCardInfo.RCA << 16))，SD_EnableWideBusOperation(SDIO_BusWide_4b)，然后就可以调用扇区读写操作了。-the stm32 SDIO operation of the register version, is changed depending on the version of library functions, does not support multi-block write, looks like the original bug in the library function is temporarily unable to solve. Turn to call SD_Init (), SD_GetCardInfo (&　SDCardInfo) SD_SelectDeselect ((u32 Bases the) (SDCardInfo.RCA < <　16)), SD_EnableWideBusOperation (SDIO_BusWide_4b), then you can call the sector read and write operations use.
