(1)Both axf and elf are executable files generated by the compiler. The difference is: The axf file is compiled by ads.The ELF file is compiled by GCC. Although the two are similar, they are still different. This is a file format difference and does not involve debugging formats. (2)Axf/elf is a Formatted ImageBin is the representation of a direct memory image. T

SectionSimilarly, we first give the section structure:Typedef struct{Elf32_word sh_name;/* index in section string table */Elf32_word sh_type;/* section type */Elf32_word sh_flags;/* Section flags */Elf32_addr sh_addr;/* Section virtual ADDR at execution */Elf32_off sh_offset;/* section File offset */Elf32_word sh_size;/* section size in bytes */Elf32_word sh

The structure of the elf file is as follows:The elf file consists of 4 parts, namely the Elf header (elf header), the Program Header table, the section (Sections), and the section Header table.In fact, a file does not necessarily contain all of this content, and their location may not be as shown in this arrangement, o

Simply put, the entire process is divided into three steps: 1) create an independent virtual address space; 2) read

The elf file (target file) format is mainly three kinds:1) can redirect files : The file holds the code and the appropriate data, which is used to create an executable file or a shared target file together with other target files. (The target file or the static library file, which is usually a file with a. A and. o suffix of Linux)2) executable file : The file holds a program to execute. (e.g. BASH,GCC, etc.)3) share the destination file : Shared libr

In the development of ARM-based embedded systems, there are usually two types of GCC tool chains that use cross-Compilation: Arm-Linux-* andArm-elf-*, the main difference between the two lies in the use of different C library files. Arm-Linux-* uses GNU glibc, while arm-elf-* generally usesUclibc/UC-libc or newlib. glibc, a C Library specially developed for embedded systems, using RedHat. Uclibc/UC-libc and

The generic Elf file consists of three index tables: Elf Header,program header table,section Header table.1 ELF Header: At the beginning of the file, a roadmap was saved, describing the organization of the file.2 Program Header table: Tells the system how to create a process image. The target file used to construct the process image must have the Program Header t

In the uClinux kernel of the arm board, BOA is sometimes used as a web server,Unlike the Linux Kernel on the arm board, uClinux uses the arm-elf-GCC compilation tool, There are two methods to compile BOA in the uClinux kernel,First, when porting the uClinux kernel, use the BOA provided by uClinux to compile it with the kernel,There are a lot of introductions about this method on the Internet. I will not describe it hereSecond, compile the uClinux kern

What is the difference between arm-elf and arm-linux-general Linux technology-Linux programming and kernel information? For more information, see the following. The following are the differences between the two cross-compilation environments: These two cross environments have been used In the development of ARM-based embedded systems, there are often two types of GCC tool chains that use cross-Compilation: arm-linux-* and arm-

In ARM-based embedded system development, there are two GCC tool chains that often use cross-Compilation:The main difference between ARM-Linux-* and arm-elf-* is that they use different C-library files.

The basic file formats of the arm system are commonly used in ARM-based embedded system development.There are three basic file formats for the arm system:1) bin, flat-board binary format, which is generally used for Directly Writing to flash and loading to the monitor program.2) Elf, executable and linkable format, a common object file format, generally generated by GNU Compiler Collection (GCC.3) axf, an extended version in Bin format. The main part

Android OS added support for 64-bit programs after 5.0, compatible with running 32-bit processesThe majority of the Android process is zygote the parent process fork out of the child processThe process that the zygote process is fork out is a 32-bit processThe process that the zygote64 process is fork out is a 64-bit processBut there are some processes before zygote start, that is, the init process fork, all belong to the 64bit processZygote process changes the name of the process after it has b

Elf is a Unix-like system and of course includes executable file formats on Android (also including. So and. O class files). Can be understood as an EXE or DLL file format on an Android system. Understanding the Elf file specification is a prerequisite for understanding process loading and execution on an Android system. Let's take a closer look at what this elf

1. OBJ fileProgrammers write programs by writing a binary file. If we declare a variable char C, that is, the Declaration requires an 8-bit space, then we need to declare to the system that the 8-bit space is reserved. How can we do this? It is to compile a special binary file-OBJ file. The execution file obtained by using the C language compiled by GCC contains not only CPU commands, but also a lot of other information, it has many coff, elf ...... I
