我新装的ADS1.2,

操作步骤如下：File->New->roject->Arm Executable Image  然后添上工程名字，确定，

              右键->Add Files   添加  Init.s,Main.c

Init.s :

IMPORT Main
AREA init,CODE,READONLY
ENTRY
LDR R0, =0x3FF0000;
LDR R1, =0xE7FFFF80;//配置SYSCFG，片内4K Cache，4K SRAM
STR R1 [R0]
LDR SP,0x3FE1000;  // SP指向4K SRAM的尾地址，堆栈向下生成
BL Main
B .
END

Main.c :

#define IOPMOD  (*(volatile unsigned *)0x03FF5000)
//register
#define IOPDATA (*(volatile unsigned *)0x03FF5008)
//register

void Delay(unsigned int);
int Main()
{
    unsigned long LED;
    IOPMOD = 0xFFFFFFFF;
    IOPDATA = 0x01;
    for(;;)
    {
        LED = IOPDATA;
        LED = (LED << 1);
        IOPDATA = LED;
        Delay(10);
        if(!(IOPDATA & 0x0F))
          IOPDATA = 0x01;
         
    }
    return(0);
}

void Delay(unsigned int x)
{
    unsigned int i,j,k;
    for(i = 0; i <= x; i++)
      for(j = 0; j < 0xff; j++)
        for(k = 0; k < 0xff ;k++);
}

编译并MAKE后，却显示  IMPORT Main  为 Unknown opcode
          AREA init,CODE,READONLY  为 Unknown opcode
                            ENTRY  为 A Label was found which was in no AREA

请了解的朋友帮助一下！谢谢！
