在 μC/OS-II 上的移植，主要是针对与 CPU 或编译器相关的文件和操作系统模拟层来

进行移植，并简要描述了 LwIP 对下层的网络接口和上层的应用程序接口的编程模

型。针对以太网控制器和网络物理层芯片的硬件特征，实现了以太网驱动程序，主

要完成以太网的初始化、中断处理以及数据的接收和发送等功能，为 LwIP 提供驱动

支持。根据嵌入式应用开发的需要，在 LwIP 协议栈的基础上实现了 TFTP 协议以及

网络烧写服务器，为 Bootloader 提供有实用性的网络下载功能-In μC/OS-II on the transplant, mainly for the CPU or the compiler and associated files and operating system emulation layer to transplant, and a brief descr iption of the LwIP network interface on the lower and upper application program interface of the programming model. For the Ethernet controller and the network physical layer chip hardware features to achieve the Ethernet driver, mainly to complete the initialization of the Ethernet, interrupt handling and data receive and transmit functions, to provide driver support for the LwIP. According to embedded application development needs, LwIP stack on the basis of the TFTP protocol and the programming server network for the provision of practical network Bootloader download
