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！
