TI中文支持网你好，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 – DebugUpdating build tree…LinkingWarning[w60]: The entry point label "__program_start" was not found in any input file. The
image will not have an entry point.Error[e46]: Undefined external "__program_start" referred in ?ABS_ENTRY_MOD ( )Error while running Linker
Total number of errors: 1Total number of warnings: 1
请问这是为什么啊？我该怎么改呢？谢谢！
Peter_Zheng：
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：

请问这是我哪里设置错误了…
