Boot Sequence翻译成中文是引导顺序、启动顺序,是学习linux的一个重要的知识点,也是一个基础的知识点,做下笔记。 Linux Boot Sequence: 1、load bios(hardware information) 加载BIOS(硬件信息),BIOS:Basic Input Output System(基本输入输出系统),是一组固化到计算机内主板上一个ROM芯片上的程序,它保存着计算机最重...
so most of data are used at runtime or hard-coded in kernel asplatform data. But each board would have to have a kernel tailored for that platform. So the solution isDevice Treeand one kernel fits them all. since 2013 linux 3.8

ARM Linux Boot Sequence The following traces the Linux boot sequence for ARM-based systems in the 2.6.18 kernel. It looks at just the earliest stages of the boot process, until the generic non-processor-specific start_kernel function is called. The line numbers of each statement are in paren...
Boot sequence (in order) Boot ROM X-loader U-boot Linux At power-up an OMAP3 device begins booting from internal Boot ROM. This code is fixed during the manufacturing process and cannot be altered. The Boot ROM reads boot configuration pins (SW4 on the OMAP3 EVM) which tell the B...
Linux Booting Process: A step by step tutorial for understanding Linux boot sequence One of the most remarkable achievement in the history of mankind is computers. Another amazing fact about this remarkable achievement called computers is that its a collection of different electronic components, and ...

Linux开机启动(bootstrap) 计算机开机是一个神秘的过程。我们只是按了开机键,就看到屏幕上的进度条或者一行行的输出,直到我们到达登录界面。然而,计算机开机又是个异常脆弱的过程,我们满心期望的登录界面可能并不会出现,而是一个命令行或者错误信息。了解计算机开机过程有助于我们修复开机可能出现的问题。
