No Elf file associated with target - Vivado 2016.4 如何解决

1.在使用vivado 2016.4和SDK 2016.4遇到这样的问题：

调试如果选择GDB遇到这样的问题：

error while running ps7 init method. No Elf file associated with target

这是vivado2016.4的bug



Description 问题描述

GDB/XMD debug will not work for the Zynq designs created using Vivado 2016.4. 
GDB/XMD debug 在使用 Vivado 2016.4 创建 Zynq 设计时不工作。

This is due to the “-force” option added to the mwr command in the ps7_init.tcl file for new 2016.4 Vivado based designs. 
这是因为，在 ps7_init.tcl 文件中 mwr 指令的 “-force” 参数。

This “-force” option is not supported for the mwr command in XMD. As a result, the GDB Debug flow is not working for Zynq designs. 
mwr 指令的 “-force” 参数在 XMD 中不支持。因此，GDB Debug 不能在创建 Zynq 设计时工作

How can I resolve this issue? 
如何解决？

解决方案：

方案1.替换xmdterm.tcl 文件：

复制下面代码改名为xmdterm.tcl 资源，然后到你的SDK的安装目录下替换原来的xmdterm.tcl

    其实最先朋友让我就这个题目写篇文章的时候，我是拒绝的，因为觉得苹果就是在炒冷饭， 把已经流行了数十年的OOP中的“面向接口编程”还拿来讲，看完整个Session之后呢，虽然还是觉得在炒冷饭，但是毕竟还是加了蛋的，有些东西还是值得说说的。 通常谈到面向接口编程，其主要作用是把系统设计和具体实现分离开，让系统的每个部分都可以在不影响别的部分的情况下，改变自身的具体实现。接口的设计就反映了系统

  • Spring MVC 方法注解拦截器 xp9802 spring mvc
    应用场景，在方法级别对本次调用进行鉴权，如api接口中有个用户唯一标示accessToken,对于有accessToken的每次请求可以在方法加一个拦截器，获得本次请求的用户，存放到request或者session域。 python中，之前在python flask中可以使用装饰器来对方法进行预处理，进行权限处理 先看一个实例,使用@access_required拦截： ?
