前一段時(shí)間在玩xilinx送我在跑XUPV5-LX110T，首先跑xilinx給出的XUPV5-LX110T的demo設(shè)計(jì)，結(jié)果發(fā)現(xiàn)遇到了一些錯(cuò)誤但是自己在網(wǎng)上發(fā)現(xiàn)很少有答案，就把自己的一些總結(jié)貼出來：

(1)xupv5_bsb_std_ip時(shí)出現(xiàn)了問題，其錯(cuò)誤描述如下：

[xupv5_bsb_system.ucf(1110)]: NET xps_iic_0_Gpo_pin not found. Please

verify that:

1. The specified design element actually exists in the original design.

2. The specified object is spelled correctly in the constraint source file.

IOSTANDARD=LVCMOS33;> [xupv5_bsb_system.ucf(1111)]: NET xps_iic_0_Gpo_pin

not found. Please verify that:

1. The specified design element actually exists in the original design.

2. The specified object is spelled correctly in the constraint source file.

make: *** [__xps/xupv5_bsb_system_routed] Error 1

解決辦法：打開xupv5_bsb_std_ip文件夾里面的xupv5_bsb_system.mhs文件，

在其80行的位置，將PORT xps_iic_0_Gpo_pin = xps_iic_0_Gpo, DIR = O, VEC = [31:31]注釋掉(即在前面加上#即可)或刪除。

在其551行的位置，將 PORT Gpo = xps_iic_0_Gpo注釋掉(即在前面加上#即可)或刪除。

保存該文件。

然后打開xupv5_bsb_std_ip文件夾里面的xupv5_bsb_system.ucf文件

在其1110行和1111行的位置，將Net xps_iic_0_Gpo_pin LOC=AK6; # DVI_RESET_B

Net xps_iic_0_Gpo_pin IOSTANDARD=LVCMOS33;兩行刪除或者注釋掉。

保存該文件即可。

Done!

看到了這個(gè)問題，首先要學(xué)會(huì)自己找，上面明顯提示是lwip出錯(cuò)，我們看一下datasheet就會(huì)發(fā)現(xiàn)： lwIP provides an easy way to add TCP/IP-based networking capability to an embedded systemlwip_v3_00_a in EDK provides adapters for the xps_ethernetlite and xps_ll_temac

Xilinx? Ethernet MAC cores, and is based on the lwIP stack version 1.2.0. This document

describes how to use lwip_v3_00_a to add networking capability to embedded software. 我們知道了它的作用，那就找吧，反正，xilinx里面是以mhs和mss文件為主線，那就行動(dòng)吧

解決辦法：在mss文件里找到# BEGIN LIBRARY

PARAMETER LIBRARY_NAME = lwip

PARAMETER LIBRARY_VER = 3.00.a

PARAMETER PROC_INSTANCE = microblaze_0

PARAMETER api_mode = SOCKET_API

END

將其注釋掉或者刪除。

解決辦法：到桌面右鍵單擊我的電腦，選擇屬性，再選擇高級(jí)這一欄，單擊環(huán)境變量，在新彈出的環(huán)境變量對(duì)話框下，單擊系統(tǒng)變量的新建按鈕，輸入變量名：CYGWIN

在變量值中輸入：nontsec，單擊OK，重新啟動(dòng)XPS，重新編譯即可。

解決辦法：This error can be safely ignored as it is being generated incorrectly. The project will implement.

官方給出的答復(fù)是忽略這個(gè)錯(cuò)誤。
