程序无法LOAD到外部存储器

Other Parts Discussed in Thread: TMS320F2812

我们现在使用TMS320F2812，外扩两片8位512k的存储器，组成512k 16位的外部存储器，使用ZONE2存储空间，

PAGE 0：

EXROM : origin = 0x080000, length = 0x040000

PAGE 1：

EXRAM : origin = 0x0C0000, length = 0x040000

现在问题是如果吧.text段分配到EXROM，LOAD程序的时候就出错，错误见附件。

但是如果是把大数组分配到EXRAM，则可以正常读写。

请问这个问题怎么解决？

    .text段里面存的是代码，就是Code。其中有一部分code是用来初始化外部的extern memory的。

    所以那部分代码需要放到内部的Ram中，当配置好外部的external memory之后，才能使用。

    因此您把数据区放到external memory是可以的。大数组存在.ebss里面，而code存在.text里面。

    谢谢你的回答。我把.text段分配到了RAMH0，可以运行。

    但是我的目的是想把程序代码分配到外部RAM中去，例如我现在试了，

    #pragma CODE_SECTION(func,"dlFile")

    void func(void);

    在CMD文件中

    PAGE 0：

    EXROM      : origin = 0x080000, length = 0x040000

    dlFile : > EXROM,      PAGE = 0

    load程序的时候还是LOAD不进去，错误如下：请问这是什么问题啊？

    建议将.text段放到RAMH0中，将代码放到内部RAM是最佳的选择，将数据放到外部RAM。

    原因我上面的回答已经讲了。

    至于将某个函数放到其他的空间，可以参考InitFlash这个函数的用法，在TI的Flash历程里面有。
