我正在使用基于NUCLEO-F207ZG板和stm32f207ZGT的继承项目，作为IDE我使用SW4STM32（Eclipse，AC6）。
这个项目在其他电脑上编译正常，但由于距离原因，我不能用它来比较配置。
导入后没有错误我尝试编译它得到控制台输出：

在互联网上进行一些搜索之后，这似乎是由链接器引起的：

我没有想法，我尝试过手动修改链接器和makefile，但它最糟糕。
感谢您的帮助!!
修改
如果我删除（注释）链接的最后几行，那么它可以工作，但我不能这样做是因为这是一个自动生成的文件。
链接器中的修改：

我不知道为什么，但现在我有硬件进行测试，该项目没有我在编辑
中评论的行编辑： 问题在于为LWIP生成的cubemx代码。
