并在/mnt/mem 目录下创建 test.img 文件作为 U 盘存储
dd if/dev/zero oftest.img bs1M count2048 这里注意一点img文件并不能被格式化则上述U盘脚本中的 如下格式化的部分需要注释掉否则有问题。

}创建后在windows下访问时先要将其格式为NTFS等。 以U盘SATA盘等为存储介质 首先格式化为NTFS然后运行上述脚本进行usb 设备创建。 将开发板插入到windows下可以直接作为U盘使用不需要格式化等额外操作。 可以实现linux 下面写而windows读的满足类似移动硬盘的应用场景。 性能测试 在windows下用 CD 工具压测环境采用USB3.0的接口特别要注意线缆的选择用2.0的线缆是。
