按照第4讲，建立MDK STM32的工程模板，报错，

万水千山

..\OBJ\Template.axf: Error: L6218E: Undefined symbol main (referred from rtentry2.o).

按照第4讲，基于MDK的  STM32的工程模板，报错，怎样解决

万水千山

 在代码最后加回车符号，怎样加

万水千山

 我用的是Mini型的板，用开发板例程，放到工程里还是报错

我按照 基于STM32固件库V3.5建立keil工程详细步骤.pdf，

main.c文件里输入

        #include "stm32f10x.h"

       int main(void)
  {
       while(1)
      {
           ;
      }
   }
 编译报错：
显示Build target 'Template'
compiling main.c...
*** Error: Referred Memory Range 'ROM1' is undefined.
