2808编译成功，无法运行程序

只看该作者 · 2009-11-3 13:16

我使用的是CCS3.3+补丁，仿真2808simulation形式，不连接仿真器。编译一个很简单的cputimer0中断导致GPIO端口反转的例子。使用的是2808头文件里面自带的“2808_RAM_lnk”这个cmd但是发现编译之后会有很多warning。但是我对比map检查了cmd没有问题，然后我就运行这个程序但是在加载out文件的时候出现了“Trouble Writing Memory Block at 0x3fb000 on Page 1 of Length 0x100: Cannot access memory address 0x3FB000”这个错误。希望大家帮忙分依稀下是哪里出现了问题？
对应的cmd上传到附件里面了。
下面是编译提示：

你使用了TI的外设寄存器文件库，但是cmd文件里面没有定义这些寄存器文件所在的section，你需要自己把这些寄存器文件对应的section定义加入到cmd中。

问题和之前的一样还是0X3FB000这个地址没有办法下载内容，但是这个地址明明就是我定义好的数据段呀，而且我检查了v2808的map，其中0x3fa000~0x3fc000都是sram，我将前一半放到了程序段，后一般放到了数据段，这样应该没有问题吧？

或者是.ebss .econst这两段的内容加起来超过了DRAMH0的大小。
如果是单独一段超过的话会有错误，两段的和超过大小不知道会不会提示。
你看一下map文件，各段大小和使用情况

我都没有使用仿真器仅仅是电脑的sim仿真，因此不存在芯片的问题。只能单独看看是不是超过了这个范围。不过应该不会，我的程序非常简单。几乎和例程里面的cpu_timer0一样小，因此不可能会出现不够的情况呀？

我在打开软件的时候就提示错误了。可能我配置不对，以前没用过软件仿真。是不是你的也有这个问题？
都要设置什么啊

Trouble Writing Memory Block at 0x3fa442 on Page 0 of Length 0x442: Cannot access memory address 0x3FA000
我的是这样的提示
于是我把有关H0的部分都改到L0 和L1就没问题了

软仿真的存储器地址分配不同，具体有什么区别我还没找到，
需要重新定义cmd,虽然编译没错，但是不能运行。
在软件仿真下，程序代码存储区好像必须设置在1000h以后。
而程序复位必须设置为：VECS:origin =0h
有待证实

之前也没有做过单纯的软件仿真，都是在开发板上跑程序，我上面的设置在开发板上没有问题。估计就是地址分配的问题。唉还得查查资料。

刚才尝试着修改了一下，可以运行，load也没有问题。不过程序会停在关闭看门狗那句上，有一个while循环，等待标志位置一，因此我怀疑还是编译CCS设置的问题吧？又或者CCS本身只能最编译的检查而不能真正的仿真出结果？？这个太奇怪了吧？估计还是设置有问题，希望有哪位用过2808的simulator模式的朋友能指导一下。

只看该作者 · 2009-11-8 09:55

我两种simulator都用过了，我觉得还是跟地址分配有关，程序会停留在初始化阶段，就是某个地址不对，没法初始化。

2808编译成功，无法运行程序
