c - STM32f207ZG NUCLEO 板，ld.exe : section . RxDescripSection VMA [2000e000,2000e09f] 与 .bss VMA 部分重叠 [20000118,2001431b]

Question

我正在开发一个基于 NUCLEO-F207ZG 板和 stm32f207ZGT 的继承项目，作为 IDE，我使用 SW4STM32(Eclipse、AC6)。

该项目在其他电脑上编译正常，但由于距离原因我无法使用它来比较配置。

导入没有错误后，我尝试编译它并获取控制台输出:

Building target: STM32F207ZG_NUCLEO_144.elf

15:59:47 Build Finished (took 23s.436ms)

在网上搜索了一下，这似乎是由链接器引起的:

我没有主意了，我尝试过手动修改链接器和 makefile，但效果最差。

感谢您的帮助!!

编辑:

如果我删除(注释)链接器的最后几行，那么它就可以工作，但我不会这样做，因为它是一个自动生成的文件。

链接器中的修改:

我首先对这行进行了评论编辑，来自ethernetif.c，并且最确定我需要主题。

我不知道为什么，但现在我有了要测试的硬件，该项目可以在没有我在编辑中评论的行的情况下运行

编辑:问题出在cubemx 为LWIP 生成的代码中。
