修改方案：
|
||
|
|
|
||
|
|
### SD 初始化
|
||
|
|
***创建文件失败错误***
|
||
|
|
SDIO.c文件
|
||
|
|
hsd.Init.BusWide = SDIO_BUS_WIDE_1B;
|
||
|
|
hsd.Init.ClockDiv = SDIO_INIT_CLK_DIV; //SDIO_TRANSFER_CLK_DIV;
|
||
|
|
|
||
|
|
### DMA
|
||
|
|
|
||
|
|
FIFO WORD
|
||
|
|
|
||
|
|
|
||
|
|
### 中断
|
||
|
|
|
||
|
|
SDIO 优于 DMA 优于 USB
|
||
|
|
值正好相反
|
||
|
|
|
||
|
|
|
||
|
|
### heap stack
|
||
|
|
0x1000
|
||
|
|
ox1500
|
||
|
|
|
||
|
|
f_mount等要放任务中，增加了堆栈大小
|
||
|
|
StartDefaultTask 堆栈要调大 1024
|
||
|
|
|
||
|
|
|
||
|
|
### 最大最小扇区大小
|
||
|
|
|
||
|
|
512 -> 4096
|
||
|
|
FATFS 两处地方
|
||
|
|
USB_Device 两处地方
|
||
|
|
|
||
|
|
### USB 的调整
|
||
|
|
|
||
|
|
***CubeMX 自动将 MX_USB_DEVICE_Init() 函数放到 StartDefaultTask 中 ***
|
||
|
|
|
||
|
|
优于定义了 StartDefaultTask 虚函数， 不执行
|
||
|
|
需要手动移植到实际函数中
|
||
|
|
|
||
|
|
USB_Device初始化函数在默认任务中，所以要增加默认任务 StartDefaultTask 的堆栈，
|
||
|
|
|
||
|
|
MX_USB_DEVICE_Init();
|
||
|
|
|
||
|
|
### 重写usbd_storage_if.c
|
||
|
|
USB_DEVICE\App\usbd_storage_if.c
|
||
|
|
*** 不写的话 读取不到Upan信息， 显示upan大小都不对 ***
|
||
|
|
|
||
|
|
#define STORAGE_LUN_NBR 1 // 逻辑单元号,只有一个外部flash,设置为1
|
||
|
|
#define STORAGE_BLK_NBR 2048 //扇区的数量,外部flash的大小是8Mbyte，有128块，每块16个扇区，故128*16=2048个扇区
|
||
|
|
#define STORAGE_BLK_SIZ 4096 // 每个扇区的大小,外部flash扇区的大小为4096byte/
|
||
|
|
以上通过输出SD信息改写
|
||
|
|
|
||
|
|
因为加入了FreeRTOS，fatfs对sd卡读写用的是发送消息机制，
|
||
|
|
所以usbd_storage_if.c里的读写不能再去调用bsp_driver_sd.c里的读写方法了，
|
||
|
|
大家有兴趣的可以对比一下有无FreeRTOS，bsp_driver_sd.c源码的内容
|
||
|
|
|
||
|
|
读写方法等
|
||
|
|
|
||
|
|
STM32F407 开发板没有用到 VUSB 电压检测，所以要在 usb_conf.h 里面
|
||
|
|
将宏定义：#define VBUS_SENSING_ENABLED，屏蔽掉。
|
||
|
|
3，通过修改 usbd_conf.h 里面的 MSC_MEDIA_PACKET 定义值大小，可以一定程度提高
|
||
|
|
USB 读写速度（越大越快），本例程我们设置 12*1024，也就是 12K 大小。
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
***官方例程不支持大于 4G 的 SD 卡***
|
||
|
|
Middlewares\ST\STM32_USB_Device_Library\Class\MSC\Src
|
||
|
|
官方例程不支持大于 4G 的 SD 卡，得修改 usbd_msc_scsi.c 里面的 或 usbd_msc.h( Cubemx HAl)
|
||
|
|
SCSI_blk_addr 类型为 uint64_t，才可以支持大于 4G 的卡，官方默认是 uint32_t，最大只能支持 4G 卡。
|
||
|
|
注意： usbd_msc.h
|
||
|
|
uint64_t scsi_blk_addr;
|
||
|
|
uint64_t scsi_blk_len;
|
||
|
|
usbd_msc_scsi.c 文件，是只读的，得先修改属性，去掉只读属性，才可以更改。
