TI中文支持网28335 使用FPU时，总是报这个错误，该怎么解决
Description Resource Path Location Type
unresolved symbol __SYSMEM_SIZE, first referenced in ../lib/rts2800_fpu32.lib<memory.obj> Example_2833x_Sci_All_Echoback C/C++ Problem
Seven Han：
是说"__SYSMEM_SIZE”未被定义，可参考下：https://e2e.ti.com/support/development_tools/compiler/f/343/p/553449/2026951
还有看下工程引用的库是否被添加，检查一下其路径是否正确。

应该是缺少库 找的添加一下

现在具体情况是这样的
1.仅仅跑我的程序不使用FPU，能正常编译完成，且正常运行
2使用FPU，，使用简单的程序，能正常编译完成，且FPU正常运行
3使用我的程序，使用FPU，就会报l __SYSMEM_SIZE这个问题，且编译不通过.开始出问题了，
下面是cmd代码，以及内存使用情况
