编译出现错误，求助

错误提示如下：

 undefined                                 first referenced  

   symbol                                            in file    

  ———                                       —————-

 codestart                

error: unresolved symbols remain

 warning: entry-point symbol "codestart" undefined

error: errors encountered during linking; "./Debug/bldc_2833x.out" not built

>> Compilation failure

请问该怎么修改呢

Young Hu：

找到codestart的定义，改为code_start
