Clarify the relationship between bootloader norflash nandflash eboot nboot uboot sdram nk. Bin NK. nb0 I. Use NAND Flash to store data and programs on the handheld computer, but nor flash must be enabled. In addition to the Samsung processor, other mainstream processors used in handheld computers do not support programs directly started by NAND Flash. Therefore, you must first start the machine with a small nor flash, and then load OS and other softwa

original ymodem protocol. The first packet does not contain the total number of bytes. The ymodem under the Super Terminal should be in the ultimate version, so the official dome can only be transmitted under the Super Terminal. Ymodem is described in detail below. You will know the reason. First, we provide a simple bootloader project. Http://pan.baidu.com/share/link? Consumer id = 373630 UK = 118334538 Supported protocols: ymodem and ymodem-

The difference between bootloader and bootstrapIn "Embedded Linux Primer" see, in fact, there are some differences and imprecise places,For example, bootstrap and bootstrap loader seem to be different on PCs, but they don't affect understanding.Http://www.devbone.com/leadbbs/MINI/Default.asp?100-2246-0-0-0-0-0-a-.htmAlso such as Redboot (RedHat Embedded Debug and Bootstrap), the essence is a bootloader but

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

Iv. Commonalities of arm bootloaderFor an arm system, bootloader is essentially a "tool" for guiding and loading kernel images. In terms of implementation, it must provide the following functions. More specifically, it must do the following: (1) initialize RAM (required): bootloader must be able to initialize Ram, because in the future, the system will use it to save some volatile data, but the specific imp

First, it is usually assembly. Code : 0 is triggered by system reset at startup. Take code 2440 as an example to directly enter the FW. s file. In some BSP packages, the name of the assembly code is startup. S. The main operations are to set the CPU frequency (PLL), initialize RTC, set memory parameters, prepare to apply for Ram for the second stage of bootloader, and read the bootloader of the second stage

S3C2410 supports direct start from NAND Flash, so NAND bootloader is used. Most NAND bootloaders are divided into nboot and eboot. Code dependent on the CPU architecture is put in nboot, which is usually implemented in assembly language + C language; while eboot is usually implemented in C language, which can implement complex functions, in addition, the Code has better readability and portability.Nboot: Hardware Device initialization: Block a

Why does xen PV bootloader select bootloader = '/usr/bin/pygrub' Why? Pygrub enables you to start Linux Domus with the kernels that lie in the filesystem of the domu instead of with a kernel that lies in the filesystem of the dom0.this enables easier kernel update from domu or migration of hvm 'ed linuxes. Concept It is used as a Bootloader and provided with

Website Description: http://www.valgrind.org/Valgrind is a instrumentation framework for building dynamic analysis tools. There is Valgrind tools that can automatically detect many memory management and threading bugs, and profile your Pro Grams in detail. You can also use Valgrind to build new tools.The Valgrind distribution currently includes six production-quality TOOLS:A memory error detector, both thread error Detec Tors, a cache and Branch-prediction Profiler, a call-graph generating cache
