该开发包的PCIe例程中配置好编译环境后编译结果呈现如下问题：
unresolved symbol CSL_PCIeSerddesComEnable,first referenced in ./K2_PCIE_Init_drv.obj
unresolved symbol CSL_PCIeSerddesLaneConfig,first referenced in ./K2_PCIE_Init_drv.obj
unresolved symbol CSL_PCIeSerddesSetLaneRate,first referenced in ./K2_PCIE_Init_drv.obj
unresolved symbol CSL_PCIeSerddesSetLoopback,first referenced in ./K2_PCIE_Init_drv.obj
unresolved symbol CSL_PCIeSerddesShutdown,first referenced in ./K2_PCIE_Init_drv.obj
在K2_PCIE_Init_drv.c的文件中缺乏以上几个函数，请问有谁知道这几个函数存在于哪个文件或哪个库呢？
谢谢！
