STM32 H743 轮询SD模式
注意SD不擦除也可以写，如果SD擦除 需要查询SD卡状态，等待其擦除完毕才可以继续读写
PS:H7的DMA不需要单独配置DMA通道
datasheet中有介绍
The SDMMC host interface embeds a dedicated DMA controller allowing high-speed
transfers between the interface and the SRAM.
f_mkfs(“0:”,FM_ANY,512,work,512);
参数：path
当给定0时，
首先在驱动器上的第一个扇区创建一个分区表，
然后文件系统被创建在分区上。
这被称为FDISK格式化，用于硬盘和存储卡。
当给定1时，文件系统从第一个扇区开始创建，
而没有分区表。这被称为超级软盘(SFD)格式化，
用于软盘和可移动磁盘。
参数：au
指定每簇中以字节为单位的分配单元大小。
数值必须是0或从512到32K之间2的幂。
当指定0时，簇大小取决于卷大小。
