Briefly,Boot loader Is the firstSoftware program that runs when a computer starts. It is responsible for loadingAnd transferring control to the operating systemKernel Software (suchAs the Linux). The kernel, in turn, initializes the rest of the operating system(E.g. GNU ). I want to select bootloader for my embedded operating system and boot my most basic linux system.According to the o'reilly book I am reading, I started to select U-boot. However, during the actual operation, I found thatDon't

Ubuntu installation record for Bay Trail-T X86 Tablet I tried to install Ubuntu on two atom tablets one after another. I encountered some problems and made a simple record here, so that I could give a reference to a friend who made similar attempts. For the first time, install ubuntu 15.04x64 on Cobi cube iwork7. Iwork7 configuration: Z3735F + 2g ram + 32G eMMC; The uefi of iwork7 is 32-bit. Therefore, the bootia32.efi file is required to create an in

[] Basic knowledge of Linux: TP-Link WN823N wireless network card (RTL8192EU chip) X86-64 and AARCH64 driver installation, Purpose: Enable embedded devices similar to Raspberry Pi's AARCH-64 architecture to connect to Ethernet over a USB wireless Nic; The device has LAN interfaces. However, after the previous system firmware upgrade, the three internal network interfaces can ping each other, but none of the interfaces can ping the external network int

Stack Overflow Attack series: shellcode in linux x86 64-bit attacks get root permissions (1) how to execute functions, shellcoderoot There are already many examples of stack overflow on the Internet, but it rarely involves 64-bit linux related to the operating system. Recently, I have been researching this, so I wrote a series of blog posts, one is to help you remember, and the other is to help more people explore each other.Register The

Time passed so fast that the integrated SP1 version of Vista was released. Many of my friends are still using the XP system, and XP is about to be SP3. Windows Server 2008 is also released. It is Microsoft's last 32-bit system and will be a 64-bit system in the future. Windows Vista SP1 x86/x64 Chinese official retail edition I don't need to talk much about it. It's a good news for anyone who needs to use the Vista operating system. ==========

1. the load address is arbitrary, but was standardized back with sysv for x86. it's different for every architecture. what goes above and below is also arbitrary, and is often taken up by linked in libraries and MMAP () regions. 2. the answer is really: a bunch of things. there is no magical meaning to the load address of the executable and pretty much anything can be mapped to the lower addresses. common examples including: C library (such as the C

From: http://kerneltrap.org/mailarchive/linux-kernel/2008/4/29/1657814 AMIDS some heavy flaming, it's clear that there is a lot of confusion on how Cachability and ioremap cooperate on x86 on a hardware level, and how this Interacts with Linux (both before 2.6.24 and in current trees ). This email tries to describe the various aspects and constraints involved, In the hope to take away the confusion and to make clear how Linux works, Both in the past a

Although I am familiar with assembly language is still 108,000 miles, but at least it is used. I feel that if I want to keep my
