IAR因版本不兼容打不开工程解决.doc

本文给出IAR因版本不兼容打不开IAR工作区遇到的各种问题及解决方法，包括依据提示修改版本，删除未知名称(ewp文件)若还没解决，则创建新工作区、工程，并拷贝相关文件，我想这是一种通用化的解决方法(很诡异)PS：本文以IAR工程项目ContikiCC2530Port为例，IAR for MCS-51版本是7.51A本文记录了整个调试过程，实际场景，不妨先跳到第三部分，看行不行，不行的话，再按第二部分修改一、IAR错误提示    昨天，在GitHub下载了一个IAR工程项目ContikiCC2530Port，打开*.eww文件出现一系列错误，如下：1.1 Broken options were detected in the project file.A backup copy will be made.图1 IAR警告Broken options1.2 The project file * was created by a newer version of project and cannot be opened图2 IAR警告created by a newer version1.3 The project * could not be open图3 IAR警告could not be openBuild区域显示如下信息：LOAD: Configuration 'ContikiBankedRelease' in the project 'ContikiCC253xProj' contains broken options for tool 'General': The format of this file is not supported by this version of the workbench. It appears to have been written by a newer version of the workbench. Diagnostics: 'Settings 'General': unsupported version - '. Options for 'General' will be set to default.

It appears to have been written by a newer version of the workbench.  Diagnostics: 'Settings 'XLINK': unsupported version - '. Options for 'XLINK' will be set to default.如下图所示：图4 IAR log windows信息    初步断定，这些警告是因为IAR版本不兼容引起的，但事实上没那么简单，之前也遇见用新版本IAR打开旧版本IAR工程文件，可以直接打开(给出提示信息)，在这里还涉及到工程项目配置。

解决方法是修改相关的IAR工程文件，描述IAR工程主要有.dep、.eww(Embedded Workbench Workspace)、.ewd(Embedded Workbench Debug)、.ewp(Embedded Workbench Project)文件dep --(我也不知道)eww --工作区文件，描述工作区包含哪些project ewd --C-SPY调试器项目设置文件 ewp --IA项目的配置信息二、Broken options    Broken options是由于项目文件配置不对引起的，按提示信息修改版本不对的，修改版本；unknown name的，则删去这些配置选项2.1 General2.1.1 'Settings 'General': unsupported version(1)错误提示LOAD: Configuration 'ContikiBankedRelease' in the project 'ContikiCC253xProj' contains broken options for tool 'General': The format of this file is not supported by this version of the workbench. It appears to have been written by a newer version of the workbench. Diagnostics: 'Settings 'General': unsupported version - '. Options for 'General' will be set to default. Creating backup of original project file.(2)解决    找一个IAR现版本可以找开的工程文件，查看General的版本，并将工程文件的版本改成可支持的版本，如下图所示：2.1.2 unknown name: PDATA 8-15 register address(1)错误提示LOAD: Configuration 'ContikiBankedRelease' in the project 'ContikiCC253xProj' contains broken options for tool 'General': (Registry: unknown name: PDATA 8-15 register address) Options for 'General' will be set to default. Creating backup of original project file. (2)解决在.ewp文件找到PDATA 8-15 register address，删去...，如下： PDATA 8-15 register address  0xA0 2.1.3 unknown name: PDATA 16-31 register address(1)错误提示LOAD: Configuration 'ContikiBankedRelease' in the project 'ContikiCC253xProj' contains broken options for tool 'General': (Registry: unknown name: PDATA 16-31 register address) Options for 'General' will be set to default. Creating backup of original project file. (2)解决    同2.1.2，在.ewp文件找到PDATA 16-31 register address，删去...2.1.4 unknown name: General Far22 Heap Size(1)错误提示LOAD: Configuration 'ContikiBankedRelease' in the project 'ContikiCC253xProj' contains broken options for tool 'General': (Registry: unknown name: General Far22 Heap Size) Options for 'General' will be set to default.
