(1)xupv5_bsb_std_ip时出现了问题，其错误描述如下：
[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
解决办法：打开xupv5_bsb_std_ip文件夹里面的xupv5_bsb_system.mhs文件，
在其80行的位置，将PORT xps_iic_0_Gpo_pin = xps_iic_0_Gpo, DIR = O, VEC = [31:31]注释掉(即在前面加上#即可)或删除。
在其551行的位置，将 PORT Gpo = xps_iic_0_Gpo注释掉(即在前面加上#即可)或删除。
保存该文件。
然后打开xupv5_bsb_std_ip文件夹里面的xupv5_bsb_system.ucf文件
在其1110行和1111行的位置，将Net xps_iic_0_Gpo_pin LOC=AK6; # DVI_RESET_B
Net xps_iic_0_Gpo_pin IOSTANDARD=LVCMOS33;两行删除或者注释掉。
保存该文件即可。

看到了这个问题，首先要学会自己找，上面明显提示是lwip出错，我们看一下datasheet就会发现： 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. 我们知道了它的作用，那就找吧，反正，xilinx里面是以mhs和mss文件为主线，那就行动吧
解决办法：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
将其注释掉或者删除。

解决办法：到桌面右键单击我的电脑，选择属性，再选择高级这一栏，单击环境变量，在新弹出的环境变量对话框下，单击系统变量的新建按钮，输入变量名：CYGWIN
在变量值中输入：nontsec，单击OK，重新启动XPS，重新编译即可。

解决办法：This error can be safely ignored as it is being generated incorrectly. The project will implement.
官方给出的答复是忽略这个错误。
