ccs5编译问题

Other Parts Discussed in Thread: CONTROLSUITE

我在调试controlsuite的一个项目时出现以下问题：

当我申请一个全局变量时就出现

error: placement fails for object

  "IQmath", size 0x11a (page 0).  Available ranges:

  progRAM      size: 0x1900       unused: 0x68         max hole: 0x68      

error: errors encountered during linking;

好像是程序放不下，可我根本没有增加程序，这是什么原因？怎么解决？

我不申请变量但增加程序时反倒没有这个错误。

    这是因为您增加的变量的存储空间和IQmath的存储空间都放在同一个内存空间，就是ProgRAM，你可以看一下你的CMD文件，.ebss或者.stack应该也放在Prog. 但你的.text放在另外的区域。

    这就是之前的Prog的空间已经很满了，只要增加一个变量，那Prog就会溢出。而你增加的程序是放在另外的Ram空间的，那个空间有足够的剩余空间，因此没有错误。

    IQmath : > progRAM, PAGE = 0

    progRAM : origin = 0x008000, length = 0x001900/*x001800*/

    dataRAM : origin = 0x009900, length = 0x000800 /*x000800*/

    请问：

    0x9900+0x800=? 是否已经超过了0xA000？ 已经越界了！

    另外，可以将IQmath放到别的区域去。
