zynq中mgtx应用_基于ZYNQ的UCOS移植（TCP通讯）

周五在某小徐处借到了一块Zedboard开发板，平时在公司没有机会做SDK开发的笔记，今天就趁着这块开发板简要记录一些SDK的基本操作。一、功能简介

通过第三方库创建SDK工程

在ZYNQ-UCOS中实现TCP echo通讯

二、配置需求

操作系统	Windows 10(64位)
开发环境	SDK 2018.3

三、操作流程

1、添加资源库。启动SDK软件，选择Xilinx->Repositories弹出Perferences视图，在Local Repositories中添加ucos资源库(ucos资源库下载链接见附件部分)。

2、创建新工程。选择File->New->Application Project弹出New Project视图，输入工程名称ucos_tcp，选择操作系统平台ucos，点击Next>,在弹出的Templates选项中选择Micrium uc/OS-Ⅱ Hello World，点击Finish完成基础示例工程的创建。

3、配置emac。在ucos_tcp_bsp文件夹上单击鼠标右键，选择Board Support Pcakage Settings，在弹出的Board Support Pcakage Settings视图中选择drivers，修改ucos_emacps为emacps，单击OK完成emac的配置。

4、移植Lwip。将lwip212文件夹及内容拷贝到工程源文件目录下(Lwip资源库下载链接见附件部分)。

5、设置头文件路径，在src文件夹上单击鼠标右键，选择Properties，在弹出的Properties for src视图中选择C/C++ Build->Settings->Directories，在Include Paths中依次添加lwip212文件下的contrib、contrib/xilinx/include，lwip-2.1.2/include三个文件夹。单击Apply应用配置变更，单击OK退出Properties for src视图。

6、删除报错的头文件。

注释/ucos_tcp/src/lwip212/contrib/xilinx/include/netif/xemacpsif.h中xuartps.h的引用

注释/ucos_tcp/src/lwip212/contrib/xilinx/netif/xemacpsif.c中xuartps.h的引用

注释/ucos_tcp/src/lwip212/contrib/LwipEnter.h中platform_config.h的引用

7、修改入口函数文件。将app.c文件进行如下修改。

Include the require Micrium software components*       In the BSP setting dialog in the "overview" section of the left pane the following libraries*       should be added to the BSP :**           ucos_common*           ucos_osii*           ucos_standalone**   2. Kernel tick source - (Not required on the Zynq-7000 PS)*       If a suitable timer is available in your FPGA design it can be used as the kernel tick source.*       To do so, in the "ucos" section select a timer for the "kernel_tick_src" configuration option.**   3. STDOUT configuration*       Output from the print() and UCOS_Print() functions can be redirected to a supported UART. In*       the "ucos_standalone" section the stdout configuration will list the available UARTs.**   Troubleshooting :*       By default the Xilinx SDK may not have selected the Micrium drivers for the timer and UART.*       If that is the case they must be manually selected in the drivers configuration section.**       Finally make sure the FPGA is programmed before debugging.***   Remember that this example is provided for evaluation purposes only.

8、调试配置。调试配置如下图所示。
