root filesystem 是继工具链,bootloader, kernel之后嵌入式linux最重要的4个元素里面最后的一个。然后本章作者介绍的制作root filesystem的方法叫做RYO roll your own。但是这个方法只是教育目的的。作者在下一个章节里面会介绍更多工具,那些工具是工作中更常用的。 root filesystem里面有啥 kernel需要获取的root filesy...
把CONFIG_INITRAMFS_SOURCE 设置成cpio的full地址。如果用了menuconfig 的话,在general setup-》initramfs source files里面设置。然后就不需要特意去用fatload 一下ramdisk了。 device table device table是一个文本文件,然后列出了文件,directory,device nodes还有links。它能够根据你的配置在boot的时候创建一堆文件和...

A partition is a logically independent section of a hard disk drive (HDD). A filesystem is a hierarchy of directories (also referred to as a directory tree) that is used to organize files on a computer system. On Linux and and other Unix-like...
This is why we use initramfs, a minimal file system, where all the drivers and firmware are stored and load this file system into the RAM and ask linux to mount this file system during the booting process. Using kernel boot arguments, you can specify that the file system resides in RAM....
Linux系统中的根文件系统,Root FileSystem,简称为rootfs; 关于rootfs,之前一直很迷惑,不知道所要表达的真正的含义; 即便是通过buildroot自己建立了相关的rootfs之后,还是没能很明白的理解,到底rootfs是啥。 现在,突然,有那么一点明白了。 rootfs,其实就是,针对特定的操作系统的架构,一种实现的形式; ...
NVIDIA provides a tool to generate a root file system. To use the tool, navigate to the tools/samplefs directory in the extracted NVIDIA driver package:$ cd <your_L4T_root>/Linux_for_Tegra/tools/samplefs Note The tool downloads the base image, extracts the root file system, downloads ...
The Linux kernel has a built-in option to build a file system for inclusion into the kernel. The option is known as “Initial RAM File system and RAM disk.” The option takes a configuration file that describes the file system as shown in Figure 8.5. Sign in to download full-size image...
nfs:是由sun开发的一种在不同机器之间通过网络共享文件的技术。在嵌入式linux系统的开发调试阶段,可以利用该技术在主机上建立基于nfs的根文件系统,挂载到嵌入式设备,可以很方便的修改根文件系统的内容。 启动流程 内核通过一系列初始化之后,挂载根文件系统来执行应用程序. 所谓根文件系统,需要提前按照一定的文件系统的...
In fact, I have done this, and this is what you would see within this directory. So this goes to show you how to create a root file system for an embedded linux using buildroot. You can also create many other files such as u-boot files, the linux kernel, the second stage bootloader...
