周五在某小徐處借到了一塊Zedboard開(kāi)發(fā)板，平時(shí)在公司沒(méi)有機(jī)會(huì)做SDK開(kāi)發(fā)的筆記，今天就趁著這塊開(kāi)發(fā)板簡(jiǎn)要記錄一些SDK的基本操作。一、功能簡(jiǎn)介

? ? 通過(guò)第三方庫(kù)創(chuàng)建SDK工程

????在ZYNQ-UCOS中實(shí)現(xiàn)TCP echo通訊

二、配置需求

操作系統(tǒng)	Windows 10(64位)
開(kāi)發(fā)環(huán)境	SDK 2018.3

三、操作流程

1、添加資源庫(kù)。啟動(dòng)SDK軟件，選擇Xilinx->Repositories彈出Perferences視圖，在Local Repositories中添加ucos資源庫(kù)(ucos資源庫(kù)下載鏈接見(jiàn)附件部分)。

2、創(chuàng)建新工程。選擇File->New->Application Project彈出New Project視圖，輸入工程名稱ucos_tcp，選擇操作系統(tǒng)平臺(tái)ucos，點(diǎn)擊Next>,在彈出的Templates選項(xiàng)中選擇Micrium uc/OS-Ⅱ?Hello World，點(diǎn)擊Finish完成基礎(chǔ)示例工程的創(chuàng)建。

3、配置emac。在ucos_tcp_bsp文件夾上單擊鼠標(biāo)右鍵，選擇Board Support Pcakage Settings，在彈出的Board Support Pcakage Settings視圖中選擇drivers，修改ucos_emacps為emacps，單擊OK完成emac的配置。

4、移植Lwip。將lwip212文件夾及內(nèi)容拷貝到工程源文件目錄下(Lwip資源庫(kù)下載鏈接見(jiàn)附件部分)。

5、設(shè)置頭文件路徑，在src文件夾上單擊鼠標(biāo)右鍵，選擇Properties，在彈出的Properties for src視圖中選擇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三個(gè)文件夾。單擊Apply應(yīng)用配置變更，單擊OK退出Properties for src視圖。

6、刪除報(bào)錯(cuò)的頭文件。

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

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

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

7、修改入口函數(shù)文件。將app.c文件進(jìn)行如下修改。/*********************************************************************************************************** uCOS XSDK BSP** (c) Copyright 2014-2020; Silicon Laboratories Inc.,* 400 W.

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. Commercial development requires* a valid license from Micrium.**********************************************************************************************************//*********************************************************************************************************** INCLUDE FILES**********************************************************************************************************/#include #include #include #include "ucos_ii.h"#include "LwipEnter.h"/*********************************************************************************************************** LOCAL FUNCTION PROTOTYPES**********************************************************************************************************/OS_STK Polling_thread_Stk[256u];OS_STK LwipEnter_thread_Stk[512u];void MainTask (void *p_arg);void PollingTask (void *p_arg);/*********************************************************************************************************** main()** Description : Entry point for C code.***********************************************************************************************************/int main(){ UCOSStartup(MainTask); return 0;}/*********************************************************************************************************** MainTask()** Description : Startup task example code.** Returns : none.** Created by : main().**********************************************************************************************************/void MainTask (void *p_arg){ OS_CPU_SR cpu_sr; OS_ENTER_CRITICAL(); // Create Task OSTaskCreate(PollingTask, (void*)0, (OS_STK*)&Polling_thread_Stk[255u], 20u); OSTaskCreate(LwipEnter_thread, (void*)0, (OS_STK*)&LwipEnter_thread_Stk[511u], 50); OS_EXIT_CRITICAL(); // Suspend this Start Task after initialization OSTaskSuspend(OS_PRIO_SELF);}/*********************************************************************************************************** PollingTask()** Description : Polling task example code.** Returns : none.** Created by : MainTask().**********************************************************************************************************/void PollingTask (void *p_arg){ UCOS_Print ("Hello world from the main task\r\n"); while (DEF_TRUE) { OSTimeDlyHMSM(0, 0, 3, 0); UCOS_Print("Periodic output every 3 seconds from the main task\r\n"); }}

8、調(diào)試配置。調(diào)試配置如下圖所示。

9、啟動(dòng)調(diào)試。將測(cè)試PC機(jī)IP設(shè)置為192.168.1.99(與Zedboard處于同一網(wǎng)段)，子網(wǎng)掩碼為255.255.255.0。此時(shí)即可通過(guò)網(wǎng)口調(diào)試助手測(cè)試TCP的通訊功能。

四、資源鏈接
