程序写入FLASH后不运行怎么办？

除了.cmd文件配置问题，也可能是你的程序本身存在问题，导致运行到某一段代码无法往下执行。
建议可以使用2分法，通过加入GPIO翻转测试的方法检查问题出在哪段代码。

由于工程文件比较大，在RAM里仿真调试程序时，多次修改过RAM.CMD文件。现已经在RAM里仿真调试完毕，程序正常运行，各部分功能都实现了。现在需要把程序烧入FLASH里，但是在烧入FLASH后，程序就不运行了（编译都是好的，也没有报错）。
疑惑：1、程序写入RAM后，仿真都是好的（说明程序语法，逻辑都没有问题）；

            2、新建了几个LED、按键等的工程，烧入FLASH后，程序正常运行（烧入FLASH时，用的是同一个   FLASH.CMD文件）。（说明FLASH.CMD、芯片本身
             是好的）；

            3、把出BUG的那个工程中的主函数注释掉，写了一个点亮LED的主函数。在RAM里仿真是好的，正常点 亮LED。同样的问题出现了，在烧入FLASH后，就
不运行了。（说明该工程中确实有问题）；
分析后，觉得最有可能的就是问题出在CMD文件中：
        但是，既然编译器没有报错，那就应该说明FLASH.CMD文件没有问题呀；
        比较了程序正常在RAM里仿真时用的RAM.CMD文件和烧入FLASH时用的FLASH.CMD文件，各段的内存都大于RAM.CMD文件中的，也不会有问题呀。
难道是我忽略了什么吗？
求助？？？？？

可能是没有初始化FLASH，或者其它外设初始化错误，或者中断没有使能等。这个方面你可以自己检查下。
另外，是否可以将你编译生成的.map文件和代码里的codestartbranch.asm文件发出来看下？同时，请告知烧录FLASH后0x3F 7FF6和0x3F 7FF7这两个地址里的内容是什么？

用的HELLO DSP 的开发板，编程素材里没有codestartbranch.asm文件，但之前的程序写入FLASH后，是可以的，就这次出了问题。

烧录FLASH后0x3F 7FF6和0x3F 7FF7这两个地址里的内容是0x007f 、0x69cf

感谢你们无私的帮助！终于调好了，是上电引导的问题，用了TI官方的F2812.CMD和codestartbranch.asm文件，并对CMD文件稍作修改就好了。现在有一个疑惑，FLASH有那么多的区段（J， I ，H ，G 等）为什么大部分都没有用到，在官方CMD文件中未用到的，用户都可以自己定义使用吗？还有为什么没有区段B？

烧录FLASH后0x3F 7FF6和0x3F 7FF7这两个地址里的内容是0x007f 、0x69cf
--> 应该是0x003f 、0x69cf 吧？
如果是上电引导的问题，那你之前另外一个基于FLASH的测试程序为什么可以运行呢？你确定说的是GPIOF4, GPIOF12, GPIOF3和GPIOF2的电平状态吗？
各个FLASH段只是人为的区分，用户当然可以定义使用，例程只是说明如何使用，并不是实际情况。
SectorB是存在的，你可以查看数据手册的Table 3-1. Addresses of Flash Sectors in F2812 and F2811，在TI提供的cmd例子文件里，它只是把sector B放在另外一个page而已，用于存放数据，而大部分都是用于存放程序的。

对呀，我也觉得应该是0x003F，高两位本来应该是0x3F，可是从FLASH读出的数据总是是0x7F。这几天看了好多资料，可找不到问题呀，不管是用TI的例程还是自己的代码，结果都一样呀，奇怪的是，拔掉仿真器 程序依旧能上电启动运行，郁闷的不行

如果你确认这两个地址的内容存在问题，可以考虑在带仿真器的情况下，从复位开始单步运行对比看看程序是如何运行的。
