1 Purpose The linker script describes how the sections in the input files should be mapped into the output file, and  control the memory layout of the output file. 2 Simple example The simplest linker script has just one command: `SECTIONS'. Assume p…

1.MEMORY关键字用于描述一个MCU ROM和RAM的内存地址分布(Memory Map),MEMORY中所做的内存描述主要用于SECTIONS中LMA和VMA的定义. 2.SECTIONS关键字用于定义output section(输出段)的相应input section(输入段).LMA和VMA,是整个连接脚本中最为重要的部分.注:output section是实际存储在内存中的“段”,而input section是其构成成员,如.data为数据段,由所有全局变量构成(默认情况下):.t…

1.前言 链接器的默认配置允许所有有效内存的分配,你可以使用MEMORY命令来重新定义它 2.MEMORY命令 MEMORY命令描述了一个内存块的位置和大小.你可以用它来描述哪块内存区域可以被链接器使用,哪块内存区域一定要避开. 你可以将段分配到特定的内存区域内,链接器会基于此内存区域设置段地址,如果满了就会有警告,链接器是不会压缩段使之适合放到区域中 一个链接脚本最多只能拥有一个MEMORY命令,然而,你可以定义很多内存块,语法如下: MEMORY { name [(attr)] : ORIG…

1 Intro Every link is controlled by a linker script. The main purpose of the linker script is to describe how the sections in the input files should be mapped into the output file, and to control the memory layout of the output file. The linker alway…

[Debugging Information in Separate Files] gdb allows you to put a program's debugging information in a file separate from the executable itself, in a way that allows gdb to find and load the debugging information automatically. Since debugging inform…

嵌入式Linux-linux连接脚本 介绍 每一个链接过程都由链接脚本(linker script, 一般以lds作为文件的后缀名)控制. 链接脚本主要用于规定如何把输入文件内的section放入输出文件内, 并控制输出文件内各部分在程序地址空间内的布局. 链接器在进行链接时,会根据链接脚本从输入的.o文件中挑选出感兴趣的section,把它们合并生成新的section,这些新产生的section归属于目标文件的某个segment(段),并出现在目标文件中.例如file1.o和file2.o分别…

3.5.1 Simple Assignments symbol = expression ; symbol += expression ; The first case will define symbol to the value of expression. In the other cases, symbol must already be defined. The special symbol name ‘.’ indicates the location counter. You ma…

1 OverView ld combines a number of object and archive files, relocates their data and ties up symbol references. This version of ld uses the general purpose BFD libraries to operate on object files. This allows ld to read, combine, and write object f…
