reboot to bootloader

Reprinted from: http://blogs.msdn.com/yunxu/archive/2007/10/09/bootloader.aspx Embedded operating systems are becoming more and more important in embedded software development. When it comes to embedded operating systems, boot loader is an indispensable topic, whether it is Windows CE, embedded Linux, or other embedded operating systems. Most of them require boot loader to load the operating system. When we get a new board and want to run an embedded operating system on it, the first thing we ne

1. Linux kernel Startup Process OverviewAn embedded Linux system can be divided into four parts: Boot Loader, Linux kernel, file system, and application. Bootloader is the first code executed after the system is started or reset. It is mainly used to initialize the processor and peripherals and then call the Linux kernel. After completing system initialization, the Linux kernel needs to mount a file system as the root file system ). The root file syst

The installation of crux in the evening is always not installed. The main reason is that no bootloader is installed successfully or the configuration of bootloader is not successful. Refer to other articles on the Internet, I think it takes so much time to start crux installation and configuration by using Lilo. 1, because the use of the crux 2-2 version, refer to the official manual http://crux.nu/Main/Han

Reproduced, the source is unknown, the article is very good. One. bootloader Introduction Bootloader is the hardware in the power-on, in addition to the BIOS curing program to run the first software, responsible for loading the real operating system, can be understood as a very small OS. Currently in the Linux platform mainly has LILO, grub and so on, in the Windows platform mainly has NTLDR, bootmgr, GRLDR

Space LPC2200 Series Bootloader implementation process: There are similar implementations on the Internet, with NXP's official offer, this easy to obtain, on the Lpcware website can download the latest version, relatively speaking, this is a relatively complete project. And Zlg, AN070701, I looked at it, as if it was boot, and application in a project, this for me, not quite suitable, I want to do is two independent project, a boot, an app, but the ab

A new BootLoader boot guide method [Date:] Source: single-chip microcomputer and Embedded System Application Author: Xi'an University of Electronic Science and Technology Li Bo [Font:Large Medium Small] 　 IntroductionBootLoader is usually referred to as "System Boot Loader", which is the first program code executed after the system is powered on or reset. The main task of this program is to implement hardware device initialization

Parameter transfer of BootLoader and Linux kernel-general Linux technology-Linux programming and kernel information. For details, see the following. In an embedded system, BootLoader is used to initialize hardware, load the kernel, and pass parameters. Because the hardware environment of the embedded system is different, the BootLoader of the embedded system is a

Http://www.elecfans.com/article/87/107/2009/2009032939161.html During large-scale embedded system development, bootloader is often required to load and boot the system kernel. Most of the existing boot and boot modes require the line between the target machine and the host machine.Connection, which is inconvenient to use and inefficient. Based on the analysis of the existing loading and boot guide methods, this paper proposes an improved method, that

Software Architecture for LinuxIn the Linux system software architecture can be divided into 4 levels (from low to High respectively):1. Boot loader2. System kernel3. File system4. User ProgramBoot loader:The boot loader (BootLoader) is a boot code that is cured in hardware flash and is used to complete some basic configuration of the hardware and boot the kernel.System kernel:The system kernel (Kernel) is the lowest level of the entire operating syst

I had nothing to do in the company yesterday, so I had a rare opportunity to add value to myself. I watched two video tutorials on WindowsCE and recorded the bootloader. At the beginning, I was not very clear about the usage of bootloader. I only knew that it was called a system boot program. It was responsible for OS startup, but how was it started? What other functions does it have? How is it implemented

1. What is bootloader? In short, bootloader is a small program that runs before the operating system kernel runs. Through this small program, we can initialize hardware devices and build a map of memory space to bring the system's hardware and software environment to a suitable state, in order to prepare the correct environment for the final call to the operating system kernel. The Android system is based

on the New Technology of Embedded Software Remote self-updating mainly focuses on the design of the update method, and there is no in-depth research on how to ensure the reliability of the update process. The reliability of updates is mainly affected by two factors: first, the reliability of remote data transmission Update and the reliability of startup after system update. Embedded Linux and WindowsFor more complex operating systems such as Ce, an independent

self-test (POST), the connection operating system , and the interface that connects the operating system to the hardware. --Excerpt from Wikipedia In short, (U) EFI is an alternative to the traditional BIOS specification, OS startup phase we can no longer deal with the troublesome BIOS. And because Uefi completely uses the C-style programming interface, it means that we can only use C, C + + to guide our OS. Development Uefi can use EDK, however, in comparison, Intel's EFI Toolkit is n

Running GNU/Linux systems on dedicated embedded boards has become increasingly popular. An embedded Linux system can be divided into four levels from the software perspective: 1. Boot LoadingProgram. Includes the firmware (firmware) bootCode(Optional), and bootloader. 2. Linux kernel. Customized kernel and kernel startup parameters specific to embedded boards. 3. file system. Including the root file system and the file system built on t

Transferred from: http://www.veryarm.com/1491.htmlThe ARM Linux startup process is roughly:bootloader ---->kernel---->root filesystem. Bootloader is a power-up to get control of the CPU, and bootloader implements the initialization of the hardware. Bootloader has become the "first to eat crab" code after power on.When it comes to this, you have to think about how

1. text//specifies that subsequent compiled content is placed in the code snippet "executable" 2.Global //tells the compiler to follow a globally visible name "either a variable or a function name" 3_start/*the real address of the function is also the starting address of the program that compiles and links enough. Since the program is loaded by the loader, the function of the _start name must be found, so the _start must be defined as global so that it exists in the compiled global compliance t

Since December 15, my spare time has been tossing the PIC32MZ EC Starter Kit purchased at the end of 15. and successively wrote more than 10 essays documenting the course of my toss. Recently completed by the C language to achieve the PIC32 UART bootloader, the use of serial communication, suitable for Microchip PIC32MZ EC, the corresponding modification can also be applied to PIC32MX, PIC32MZ EF and so on.
