TI中文支持网我是一个初学者，
1、我的工程基于tm4c123gh6pmI芯片的ek-tm4c123gxl开发板中usb_dev_bulk例程，完全复制，就是调不通，应该是环境配置问题，如何解决？错误如下，工程详见附件。

2、tm4c123gh6pm与tm4c123gh6pmI究竟有什么区别？还是一回事？末尾的字母“I”是什么意思？
3、官方有没有一个详细讲解CCS5或CCS6的环境配置的用户手册？
yongsuo ma：
例程编译通过，我是采用新建工程再添加文件、配置环境的方法创建我的工程的，可我的就是编译不过去，不知何故。

回复 yongsuo ma:
自己配置的环境没有配置好，所以出现了这个问题。你去21ic找找，我在那里发表了两个帖子，就是这个CCS和MDK工程配置的帖子。
yongsuo ma：
回复 xyz549040622:
我用笨办法，仔细比较，终于找到原因了，在工程上右键Properties~Build~ARM Compiler~Advanced Options~ Language Options~中选中Enable support for gcc extensions (–gcc)复选框，我的开发环境是CCS5.4。谢谢各位热心网友！但是我仍不知其所以然。

解决方案：Build~ARM Compiler~Advanced Options~ Language Options~中选中Enable support for gcc extensions (–gcc)复选框
工程设置几个问题：
1.Build~ARM Compiler~Advanced Options~ Predefined Symbols~添加：
ccs="ccs"PART_TM4C1230C3PMTARGET_IS_BLIZZARD_RB1
上面的器件型号和芯片版本修改为你现在用的。由于很多头文件里面需要这些预定义，例如rom.h pin_map.h。型号一定不能写错否则管脚分配就错了，因为不同型号封装不同。
2.你的工程里加入了2个启动文件，把startup.ccs移除。
3.Build~ARM Linker~ Basic Options~ Set C system stack 填写堆栈大小，默认可以512，但是根据你的代码来。堆栈太小而代码局部变量太大可能会溢出，
4.Build~ARM Linker~ File search Path~ 把driverlib.b文件路径写到“Include Library or command file as input”
5. Clean Project 之后再重新编译就好了。
针对这类问题，实际上有很多办法可以解决。我们建议先从TivaWare中建好的工程入手，先熟悉源码、启动文件、Linker文件、头文件等路径关系，然后再创建自己的工程。

我昨天还看到你给这个帖子的回复，说是解决了。怎么上来就看不到回复了？奇怪

我也觉得很奇怪，为什么我的回复没有了呢？再回复一次：
我用笨办法，仔细比较两个工程的配置，终于找到原因了，在工程上右键Properties~Build~ARM Compiler~Advanced Options~ Language Options~中选中Enable support for gcc extensions (–gcc)复选框，我的开发环境是CCS5.4。谢谢各位热心网友！但是我仍不知其所以然。
顺便总结一下基于TI德仪TM4C123GH6PMI芯片的EK-TM4C123GXL评估套件的CCS5开发环境的常见环境配置，也欢迎各位网友修正补充优化总结：

解决方案：Build~ARM Compiler~Advanced Options~ Language Options~中选中Enable support for gcc extensions (–gcc)复选框
以上部分内容参考如下资料：
http://www.deyisupport.com/question_answer/microcontrollers/tiva_arm_cortex/f/96/t/61865.aspx
工程设置几个问题：
1.Build~ARM Compiler~Advanced Options~ Predefined Symbols~添加：
ccs="ccs"PART_TM4C1230C3PMTARGET_IS_BLIZZARD_RB1
上面的器件型号和芯片版本修改为你现在用的。由于很多头文件里面需要这些预定义，例如rom.h pin_map.h。型号一定不能写错否则管脚分配就错了，因为不同型号封装不同。
2.你的工程里加入了2个启动文件，把startup.ccs移除。
3.Build~ARM Linker~ Basic Options~ Set C system stack 填写堆栈大小，默认可以512，但是根据你的代码来。堆栈太小而代码局部变量太大可能会溢出，
4.Build~ARM Linker~ File search Path~ 把driverlib.b文件路径写到“Include Library or command file as input”
5. Clean Project 之后再重新编译就好了。
针对这类问题，实际上有很多办法可以解决。我们建议先从TivaWare中建好的工程入手，先熟悉源码、启动文件、Linker文件、头文件等路径关系，然后再创建自己的工程。
