fix bootloader

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. 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

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

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

Introduction There are a lot of articles on Linux bootloader on the Internet, but most of them are relatively large programs such as Vivi and blob, which are not easy to read and the compiled files are also relatively large, in addition, it is more development-oriented guiding code that needs to be reduced when made into a product, which affects the development speed to a certain extent, and has a relatively high learning overhead for beginners, here

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. The Uart

Recently has been due to the four-axis school application, has been doing this thing, hey, helpless this goods is not as simple as imagined, their own write n long flight control, also did not fly up the plane, can only use open source APM fly control Practice practiced hand Bai, backup APM burning Bootloader method, for future use!Original address: http://bbs.diywrj.com/thread-21628-1-1.htmlRequired tool Material: 1, a avrusbasp programmer and the c

Preliminary design of STM32 IAP bootloader based on TCP daniel_ustb 2015-8-22 Night Long time no write things, a lot of things happened in the previous period, now finally can calm down to the heart. Stop to look at the past self, all the way, the insistence on technology is how valuable. People's time is limited, as an embedded engineer, the love and curiosity of new technologies will produce the driving force ahead. As to what heights can be achi

Design and Implementation of secondary bootloader of the TMS320C6000 series: microprocessor and DSP | Source: electronic engineer | Author: Xie Shiyi Li yongchao Introduction With the extensive application of DSP (Digital Signal Processor) systems, the program scale is also expanding. the boot-loader of the chip itself is used to guide the DSP program through flash memory, it is often restricted by the program size and structure. For example, the pro

Bootloader is a small program that starts to run when the system is powered on. The main function is to initialize the hardware device, prepare the software environment, and finally call the operating system kernel. There are many types of Bootloader. The most common X86 systems include LILO, GRUB, and ARM architectures, such as U-boot, VIVI, and other RedBoot/Etherboot. Start the

Many articles about Linux bootloader, but most of them are about Vivi, blob and other large programs. It is not easy to read and the compiled files are large, in addition, it is more development-oriented guiding code that needs to be reduced when made into a product, which affects the development speed to a certain extent, and has a relatively high learning overhead for beginners, here we analyze a simple bootload
