;*   1) ALLOCATES THE STACK AND INITIALIZES THE STACK POINTER
;*   2) CALLS AUTO-INITIALIZATION ROUTINE

编译出错，请问__TI_TMS470_V7M3__这些定义在那里有？

我也遇到了同样的问题，可是如何重新编译RTS库？

请赐教

在用ccs3.3编译TI的官方UBL例程时出现了与上面同样的错误：

[E0004] Absolute, well-defined integer value expected                  

   .if  __TI_TMS470_V7M3__

E0002] Illegal mnemonic specified

        .symdepend ".cinit", ".bss"

请问是什么问题导致的错误，该如何解决？谢谢！
