添加API的Lib后报错

用的是ccs3.3在做Ti2808的在线烧录，添加API的lib后，系统编译报错，我在工程的Libraries中已经添加了lFlash2808_API_V302.lib

   /* Allocate program areas: */
   Flash28_API:
   {
        -lFlash2808_API_V302.lib(.econst) 
        -lFlash2808_API_V302.lib(.text)
   }                   LOAD = FLASHD, 
                       RUN = RAML0, 
                       LOAD_START(_Flash28_API_LoadStart),
                       LOAD_END(_Flash28_API_LoadEnd),
                       RUN_START(_Flash28_API_RunStart),
                       PAGE = 0

编译后，Flash2808_API_V302.lib(.econst) not found为什么啊
