IAR中程序make出错

Kyle wang

你好，我刚安装了IAR编译器，然后新建工作区->工程->c main函数

#include "io430.h"
#include "io430G2231.h"

int main( void )
{
unsigned int i;
// Stop watchdog timer to prevent time out reset`
WDTCTL = WDTPW + WDTHOLD;
P1DIR |= BIT0; //设置端口方向
while(1)
{
P1OUT ^= BIT0; //端口输出翻转
for(i = 0; i < 5000; i++);
}

}

编译出错
Building configuration: myTest - Debug

Error[e46]: Undefined external "__program_start" referred in ?ABS_ENTRY_MOD ( )

请问这是为什么啊？我该怎么改呢？谢谢！

程序本身没有问题。

该问题应该是IAR设置问题，具体设置如下：

Project->Option->Linker->Config 勾选"Override default program"

再选择"Defined by application"

谢谢您，Peter，编译这样通过了。但是点击“download and debug”出现 Stack Warning：

The stack plug-in failed to set a breakpoint on "main". The Stack window will not be able to

display stack contents.(You can change this setting in the Tools->Options dialog box.)

我假设这没有问题，点击继续，在Disassembly界面：

继续执行，出现User error: Illegal opcode found on address 0x0

请问这是我哪里设置错误了...
