你的代码 入口点 指定了吗》？在启动文件里！startUp.s 文件里，如果没有的话，程序只能从0x0开始执行啊！而在0x0都是NOP！
你的 ORG 30H 说明第一条指令在 0x30处，但是你执行是从0x0开始的，故执行不到你的程序那里去！
你把你的代码 改成
ORG0H
试试

首先打开Keil软件，打开一个工程，点击keil的编译图标，编译软件。
2.确保已经连接了仿真器，而且已经给MCU上电，然后下载程序，等待下载完成。
3.软件程序下载完成，现在就完成了程序下载，可以开始仿真了。
4.单击软件的调试图标，进入软件调试模式。
5.现在就已经打开运行模式。
6.单击全速运行，运行软件仿真。
7.程序正在全速运行。
8.仿真完成以后单击调试图标，就可以退出调试模式。
keil
Keil C51是美国Keil Software公司出品的51系列兼容单片机C语言软件开发系统，与汇编相比，C语言在功能上、结构性、可读性、可维护性上有明显的优势，因而易学易用。Keil提供了包括C编译器、宏汇编、链接器、库管理和一个功能强大的仿真调试器等在内的完整开发方案，通过一个集成开发环境（μVision）将这些部分组合在一起。运行Keil软件需要WIN98、NT、WIN2000、WINXP等操作系统。如果你使用C语言编程，那么Keil几乎就是你的不二之选，即使不使用C语言而仅用汇编语言编程，其方便易用的集成环境、强大的软件仿真调试工具也会令你事半功倍。

在void main()函数中先加一个大循环while(1){}，然后把你的程序放到大循环里，就正常了，我遇到同一问题，就是这么解决的。

……楼主是否知道单片机复位后的PC值是多少？？？？？？
回复 gan451001su：
既然知道复位后PC指向0，为何0000H没有程序？
