给28027F添加dlog出现问题

qiang zhang

我是做28027F无感控制PMSM，用的是motor ware里面的lab1b程序，想给里面添加一个dlog，但是添加完以后，编译出现如下警告

Description Resource Path Location Type
#10247-D creating output section "DLOG" without a SECTIONS proj_lab01b C/C++ Problem

然后我在28027.cmd文件里面为dlog创建了一个sections，此时警告消失，编译没有问题，但是下载到板子上以后，程序就直接到一个中断里面死循环，

interrupt void PIE_illegalIsr(void)
{

// The next two lines are placeholders
asm(" ESTOP0");

// endless hold loop
for(;;);

} // end of PIE_illegalIsr() function

是我sections创建不对吗，应该改成什么样，我对照datasheet上面的。实在找不到地方了，请大神帮帮忙解解惑，万分感谢。

下面是我的.cmd文件，我试着给dlog添加过好多次sections，但都会死在中断里面，dlog的长度是400。
