1、Linux 虚拟文件系统介绍 在Linux系统中一切皆文件,除了通常所说的狭义的文件以外,目录、设备、套接字和管道等都是文件。 文件系统在不同的上下文中有不同的含义: 在存储设备上组织文件的方法,包括数据结构和访问方法,到存储设备。 按照某种文件系统类型格式化的一块存储介质。我们常说在某个目录下挂载或卸载文件...

查看前面的代码,我们看到KERNEL_DIR变量必须在命令行上提供,指向 ESPRESSObin 之前编译的内核源代码的路径,而ARCH和CROSS_COMPILE变量不是强制性的,因为Makefile指定了它们(但是,在命令行上提供它们将优先)。 此外,我们应该验证insmod和rmmod命令是否在我们的 ESPRESSObin 中可用,如下所示: # insmod -h Usage: insmod...
