我在tornado中移植tffs时一直遇到如下错误，请高人指教：

sysTffs.o(.data+0x0): multiple definition of `mtdTable'

make.exe: *** [bootrom_uncmp] Error 0x1

我的移植步骤如下：1.confi.c中加了#define INCLUDE_TFFS和#define INCLUDE_MTD_LV160（片子是sst39vf160，片子的驱动函数没有问题）2.tffsConfig.c的开头加了FLStatus lv160MTDIdentify(FLFlash vol); 在MTDidentifyRoutine mtdTable[] = {#ifdef INCLUDE_MTD_LV160 lv160MTDIdentify,#endif ...}中加了这一条

3.在sysTffs.c中按照班子的falsh地址和大小修改了相关的宏定义，并在Makefile中添加了MACH_EXTRA = sst39vf160.o sysTffs.o。

然后做bootRom时就遇到以上的问题，我不知道怎么解决希望那位高人可以帮助在下。

不胜感激！！！
