之前一直用的是0.3.3版本，操作flash都没问题。现在换了1.0.0版本，初始化也没问题，贴上初始化程序.

v```oid rt_hw_spi_flash_init(void)
{	
	GPIO_Configuration();
	
	#if SPI_FLASH_USE_DMA
	/* Enable the DMA1 Clock */
	RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE);
	#endif
	
	/* register spi_flash device */
 	spi_flash_device.type    = RT_Device_Class_Block;
	spi_flash_device.init    = rt_spi_flash_init;
	spi_flash_device.open    = rt_spi_flash_open;
	spi_flash_device.close   = rt_spi_flash_close;
	spi_flash_device.read 	 = rt_spi_flash_read;
	spi_flash_device.write   = rt_spi_flash_write;
	spi_flash_device.control = rt_spi_flash_control;
	
	/* no private */
	spi_flash_device.user_data = RT_NULL; 
	
	rt_device_register(&spi_flash_device, "spi0",
	                   RT_DEVICE_FLAG_RDWR | RT_DEVICE_FLAG_STANDALONE | RT_DEVICE_FLAG_REMOVABLE);

spiflash = rt_device_find("spi0");
	if (spiflash != RT_NULL){
		//rt_device_set_rx_indicate(device, uart_input);
		rt_device_open(spiflash, RT_DEVICE_OFLAG_RDWR);
	}
}```
下面的程序是线程里的，应该没问题 
```#ifdef RT_USING_DFS
	{
        /* init the device filesystem */
        dfs_init();
#ifdef RT_USING_DFS_ELMFAT
        /* init the elm FAT filesystam*/
        elm_init();
		/* mount spiflash fat partition 1 as root directory */
		if (dfs_mount("spi0", "/", "elm", 0, 0) == 0){
	        rt_kprintf("SPI File System initialized!
");
		}
		else{
			rt_kprintf("SPI File System init failed!
");
		}
#endif```
