keil编译启动文件报错问题

njy

工程使用keil5编译。其中startup_stm32f2xx.s文件总报错。
当下面代码不顶格编译时：
    MODULE  ?cstartup

        ;; Forward declaration of sections.
    SECTION CSTACKATA:NOROOT(3)

    SECTION .intvec:CODE:NOROOT(2)

    EXTERN  __iar_program_start
    EXTERN  SystemInit
    PUBLIC  __vector_table

    DATA
__vector_table
报错：
EWARM\startup_stm32f2xx.s(39): error: A1163E: Unknown opcode MODULE , expecting opcode or Macro
EWARM\startup_stm32f2xx.s(42): error: A1163E: Unknown opcode SECTION , expecting opcode or Macro
EWARM\startup_stm32f2xx.s(44): error: A1163E: Unknown opcode SECTION , expecting opcode or Macro
EWARM\startup_stm32f2xx.s(48): error: A1163E: Unknown opcode PUBLIC , expecting opcode or Macro
EWARM\startup_stm32f2xx.s(50): error: A1159E: Label missing from line start
EWARM\startup_stm32f2xx.s(51): error: A1355U: A Label was found which was in no AREA

如果将上述代码顶格编译，代码如下：
MODULE  ?cstartup

        ;; Forward declaration of sections.
SECTION CSTACKATA:NOROOT(3)

SECTION .intvec:CODE:NOROOT(2)

        EXTERN  __iar_program_start
        EXTERN  SystemInit
PUBLIC  __vector_table

DATA
__vector_table
这样，报错只有一条：
EWARM\startup_stm32f2xx.s(51): error: A1355U: A Label was found which was in no AREA

网上有些说不能顶格编写，现在是否顶格都有错误，请大神指导下，如何解决这个问题，谢谢！！
