编译没有问题，但是链接有好几个如下的问题：
.Objectucos_lwip.axf: Error: L6406E: No space in execution regions with .ANY selector matching rit128x96x4.o(.data).
.Objectucos_lwip.axf: Error: L6406E: No space in execution regions with .ANY selector matching udp.o(.data).
盼高手指点，不知道这个问题怎么解决？
还有LWIP移植的时候，出现了好多这个警告，不知道怎么避免？
lwIPsrccorememp.c(313): warning: #177-D: variable "old_level" was declared but never referenced
lwIPsrccoremem.c(382): warning: #177-D: variable "lev" was declared but never referenced
谢谢

old_level是出于协议栈内部的东西，难道你修改了协议栈或者用的不是Stellaris？
