我的工程里面，错误都是这样的。
.\ethercat.axf: Error: L6218E: Undefined symbol TimingDelay_Decrement (referred from stm32f4xx_it.o).
.\ethercat.axf: Error: L6218E: Undefined symbol FSMC_NORSRAMInit (referred from fsmccfg.o).
.\ethercat.axf: Error: L6218E: Undefined symbol HW_EscReadMbxMem (referred from mailbox.o).
.\ethercat.axf: Error: L6218E: Undefined symbol HW_EscWriteByte (referred from mailbox.o).
.\ethercat.axf: Error: L6218E: Undefined symbol HW_EscWriteMbxMem (referred from mailbox.o).
.\ethercat.axf: Error: L6218E: Undefined symbol bBootMode (referred from mailbox.o).
.\ethercat.axf: Error: L6218E: Undefined symbol bsp_read_byte (referred from mailbox.o).
.\ethercat.axf: Error: L6218E: Undefined symbol bsp_read_word (referred from mailbox.o).
.\ethercat.axf: Error: L6218E: Undefined symbol nAlStatus (referred from mailbox.o).
.\ethercat.axf: Error: L6218E: Undefined symbol u8dummy (referred from mailbox.o).
.\ethercat.axf: Error: L6218E: Undefined symbol HW_EscWriteDWord (referred from stm32eschw.o).
.\ethercat.axf: Error: L6218E: Undefined symbol HW_EscWriteWord (referred from stm32eschw.o).
.\ethercat.axf: Error: L6218E: Undefined symbol bsp_read_dword (referred from stm32eschw.o).
另外，每个文件编译都通过，但是整个工程run的时候就有问题。。。

编译器在链接是出错，你查找是不是没有包含对应的h文件，或c文件，或者静态库，或者动态库。
