TI中文支持网我在调试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。

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。
