你好，
调整了F28035.cmd文件的FLASH空间分配后单步运行OK，直接运行异常，
修改如下：

直接运行后暂停显示如下：
Green Deng：
你好，编译器说明文档中对这个函数的定义解释是这样的：
_system_post_cinit(): This function is invoked during C/C++ environment setup, after C/C++ global data is initialized but before any C++ constructors are called. This function should not return a value.
找了几个同样的问题，看看是否有所帮助：
