ARM汇编程序调试

一、keil环境搭建

参考下面这个链接：
keil环境搭建

二.stm32程序

1.新建工程

双击打开keil，点击菜单栏Project–>New μVision Project，新建项目，在弹窗中设置工程项目的名称和路径，在这里，我新建名为TEST的工程文件。

2.配置环境

选择设备点击菜单中的Project，找到Options for Target ‘Target 1’并点击，在弹窗中选择相应的目标环境，此处我选的是STM32F103ZE

选择运行环境

添加源文件

右键单击Source Group 1，选择Add New Item to Group,添加Asm File (.s)文件，命名为TEST并保存。

为其添加如下代码

 AREA MYDATA, DATAAREA MYCODE, CODEENTRYEXPORT __main__mainMOV R0, #10MOV R1, #11MOV R2, #12MOV R3, #13;LDR R0, =func01BL	func01;LDR R1, =func02BL	func02BL 	func03LDR LR, =func01LDR PC, =func03B .func01MOV R5, #05BX LRfunc02MOV R6, #06BX LRfunc03MOV R7, #07MOV R8, #08	BX LR

设置仿真器模式

点击菜单中的Project，找到Options for Target ‘Target 1’并点击，选择Debug–>Use Simulator,将Dialog DLL以及Parameter处修改为自己选择的设备，OK

3.编译调试

可以看见寄存器R5,R6,R7,R8的值和程序设置一样。

三.分析HEX文件

该文件为16进制的一串字符。hex文件的第一排字符称之为扩展线性地址记录，也称为32位地址记录或HEX386记录。
在第一行数据020000040800F2中，其实际表达为0x02 0x00 0x00 0x04 0x08 0x00 0xf2。具体含义为

第一个字节 0x02表示本行数据的长度；

第二、三字节 0x00 0x00表示本行数据的起始地址；

第四字节 0x04表示数据类型，数据类型有：0x00、0x01、0x02、0x03、0x04、0x05

‘00’ Data Rrecord：用来记录数据，HEX文件的大部分记录都是数据记录
‘01’ End of File Record: 用来标识文件结束，放在文件的最后，标识HEX文件的结尾

‘02’ Extended Segment Address Record: 用来标识扩展段地址的记录

‘03’ Start Segment Address Record:开始段地址记录

‘04’ Extended Linear Address Record: 用来标识扩展线性地址的记录

‘05’ Start Linear Address Record:开始线性地址记录

然后是数据，0x08 0x00

最后一个字节 0xf2为校验和。

四、总结

通过这次实验知道了如何搭建并配置Keil嵌入式开发环境，完成一个基于STM32汇编程序的编写。了解了Hex文件格式及其前8个字节内容含义。
