2812程序编写长了出现报错-TI中文支持网

我在一个c文件里的代码如果超过450行就会报错，报错后删除几行（并不一定是IQMATH语句）就没错了。错误信息、cmd代码和map文件如下，请帮我看看怎么出现这样的问题？

错误信息：#10099-D</a> program will not fit into available memory. run placement with alignment/blocking fails for section "IQmath" size 0x210 page 0. Available memory ranges: F2812_IQmath2.cmd

Notes:
Memory blocks on F2812 are uniform (ie same
physical memory) in both PAGE 0 and PAGE 1.
That is the same memory region should not be
defined for both PAGE 0 and PAGE 1.
Doing so will result in corruption of program
