我正在開發基於NUCLEO-F207ZG板的stm32f207ZGT繼承項目，作爲IDE I使用SW4STM32（Eclipse，AC6）。STM32f207ZG NUCLEO板，ld.exe：節.RxDescripSection VMA [2000e000,2000e09f]重疊節.bss VMA [20000118,2001431b]
該項目編譯好在其他電腦，但由於距離的原因，我不能用它來比較配置。
沒有錯誤導入後，我嘗試編譯它得到的控制檯輸出：

在互聯網一些搜索後，這似乎是由連接器造成的：

我出出主意，我已經試過手動modficate連接和Makefile b這是最糟糕的。
感謝您的幫助！
編輯：
如果我刪除（評論）連接的最後幾行，然後它的工作原理，但我souldn't做這becuse是一個自動生成的文件。

只是錯誤的提供者腳本/這些額外部分的任何特殊原因？我沒有看到任何。 –
我正在開發一個使用以太網，LWIP，IBM Bluemix和MQTT的項目，但是我的第一個聯繫人，所以我懷疑這些IP中的某一個將這些行添加到鏈接描述文件 – taquionbcn
儘管我從來沒有爲Cortex寫過鏈接器文件我自己，看起來上面的文件是矛盾的。 RAM的最後一個範圍是_user_heap_stack，看起來這個文件假設_Min_Stack_Size之後的所有內容都被用作堆棧，直到_estack，這似乎是堆棧指針的初始值。額外的緩衝區和描述符完全不關心分配方案，將它們放在RAM的中間。也許把_est__ack_stack放在'_estack =。;'後面並將有問題的部分移動到0x2001E000將有所幫助。 – Vroomfondel
