最近在用51单片机SD卡+VS1003来做MP3
可是在调试的时候遇到一个很郁闷的问题，我在main函数里只是调用了一个简短的函数，还有好多函数只是定义了调试过了，还没使用到，但是我这些都放在一个工程里编译就会报错，说是
ADDRESS SPACE OVERFLOW
SPACE: DATA
...
郁闷了，我的main函数里只调用了一个简单的函数啊为什么没调用的函数KEIL也把它给塞进HEX文件里去。。。
请大虾们解决一下小弟这个问题...

（我试过把Memory Model设置为Large （我的STC12C5A60S2内部有1280的XDATA）， 可以用，但是考虑到队友那里这样设置的时候不能使用红外的功能了，不知道是为什么。。。，所以不想改Memory Model。更不想手动注释这些没调用的函数，那样太麻烦了。。。）
