未解决的符号仍然存在 Code composer studio

Question

我一直在 MSP4302355 微控制器上尝试我的第一个汇编级程序。我所做的只是将值从一个寄存器移动到另一个寄存器。但是每当我编译代码时，我都会收到错误 “错误 #10234-D：未解析的符号仍然存在

error #10010：链接过程中遇到错误； “Register_Mode_Addr_2355.out”未建成

我已经尽力了，还是没有用。

请大家帮帮我先谢谢了

“未解析的符号仍然存在”意味着链接器失败，因为它无法从您的汇编源中解析一个或多个符号，很可能是 __STACK_END 符号。建议您打开显示构建过程的控制台 window，然后滚动查看未解析符号列表，最有可能在最后。这将确认 __STACK_END 符号，这是我对问题的猜测。有点旧，但 this thread 可能会有帮助。
