startup_stm32f10x_hd.s是一个启动文件里面，是使用语言写的基本程序，当STM32上电启动的时候，会看这里的语言把这个程序，运行起来建立起来C，所以我们使用文件的原因启动文件。改文件使用的原因是Cortex-M3内核支持的指令，参考《Cortex-M3权威指南中文》内指令集章节
startup_stm32f10x_hd.s文件是ST官方提供的，该文件可以从KEIL5安装目录中找到，也可以从ST库里面找到，找到该文件后吧启动文件添加到工程里面。不同型号的芯片以及不同编译环境使用的汇编文件是不一样的，但功能相同。 对于启动文件部分，我们主要总结功能，主要功能如下：
; Reset handler ; 汇编里面注释用的是";"，相当于 C 语言的 “//” 注释符 2 Reset_Handler PROC ;PROC 是子程序定义伪指令。这里相当于 C 语言定义了一个函数为 Reset_Handler 3 EXPORT Reset_Handler [WEAK] ;EXPORT 表示 Reset_Handler 这个子程序可供其他模块调用，相当于C的函数声明;[WEAK]表示弱定义 4 IMPORT __main ;IMPORT 说明 __main 这个标号在其他文件，在链接时候需去其他文件中寻找。相当于c中引入函数声明 5 IMPORT SystemInit 6 LDR R0, =SystemInit ;把 SystemInit 的地址加载到寄存器 R0 中 7 BLX R0 ;程序跳转到 R0 中地址执行程序，即执行 SystemInit 函数内容 8 LDR R0, =__main ;把 __main 的地址加载到寄存器 R0 9 BX R0 ;程序跳转到 R0 中地址执行程序，即执行 __main 函数，执行完毕后即可进入 main 函数10 ENDP 下面是startup_stm32f10x_hd.s源代码 ;******************** (C) COPYRIGHT 2011 STMicroelectronics ******************** 2 ;* File Name : startup_stm32f10x_hd.s 3 ;* Author : MCD Application Team 4 ;* Version : V3.5.0 5 ;* Date : 11-March-2011 6 ;* Description : STM32F10x High Density Devices vector table for MDK-ARM 7 ;* toolchain. 8 ;* This module performs: 9 ;* - Set the initial SP 10 ;* - Set the initial PC == Reset_Handler 11 ;* - Set the vector table entries with the exceptions ISR address 12 ;* - Configure the clock system and also configure the external 13 ;* SRAM mounted on STM3210E-EVAL board to be used as data 14 ;* memory (optional, to be enabled by user) 15 ;* - Branches to __main in the C library (which eventually 16 ;* calls main()). 17 ;* After Reset the CortexM3 processor is in Thread mode, 18 ;* priority is Privileged, and the Stack is set to Main. 19 ;* <<< Use Configuration Wizard in Context Menu >>> 20 ;******************************************************************************* 21 ; THE PRESENT FIRMWARE WHICH IS FOR GUIDANCE ONLY AIMS AT PROVIDING CUSTOMERS 22 ; WITH CODING INFORMATION REGARDING THEIR PRODUCTS IN ORDER FOR THEM TO SAVE TIME. 23 ; AS A RESULT, STMICROELECTRONICS SHALL NOT BE HELD LIABLE FOR ANY DIRECT, 24 ; INDIRECT OR CONSEQUENTIAL DAMAGES WITH RESPECT TO ANY CLAIMS ARISING FROM THE 25 ; CONTENT OF SUCH FIRMWARE AND/OR THE USE MADE BY CUSTOMERS OF THE CODING 26 ; INFORMATION CONTAINED HEREIN IN CONNECTION WITH THEIR PRODUCTS. 27 ;******************************************************************************* 28 29 ; Amount of memory (in bytes) allocated for Stack 30 ; Tailor this value to your application needs 31 ; |
