将脉冲信号通过GPIO输入，利用Input x-bar路由到output x-bar 后,可以在GPIO输出得到相同的脉冲信号,但是中间经过CLB，将Input x-bar输入给clb x-bar 后送入CLB模块input0,然后直连通过CLB1OUT4输出到output x-bar 后，在GPIO输出得到的信号一直是低电平，两种方式都是烧录到Flash中运行，请问有什么地方有问题？相关配置如下，感觉没有发现什么问题
Susan Yang：
您是否有参考过下面文档的 9 输入 X-BAR、输出 X-BAR 和 CLB X-BAR？

,
Jerry Xu：
对参考这个配置的，配置也是按着这个来的，直接将INPUT X-BAR给到output-xbar输出没问题，用FLASH运行CLB，CMD文件用不用特别的配置？
,
Susan Yang：
您现在使用的是哪个cmd呢？在RAM下是否可以成功运行？目前好像没有在flash下运行的cmd文件以及例程。我之后会和同事确认一下
在E2E上有相关的讨论，您可以看一下

Jerry Xu：
用的SCI烧录到Flash方式，没有用RAM运行,仿真没有问题，配置也检查了，已经发到问题中，我也没有发现问题，就是一个直连信号没有逻辑处理，担心哪里配置错了导致输出不对，应该是CLB这个环节的问题，但是没有查到哪里的问题，所以请教您帮我查找下
,
Susan Yang：
Jerry Xu 说：仿真没有问题
是指连接烧写器在CCS内调试时可以正常输出？我已经就cmd咨询了国外的BU，应该明天会有回复
,
Jerry Xu：
利用C2prog直接用SCI烧录的,您看我的配置有没有什么错误？我直接不用CLB这个模块就没有问题
,
Susan Yang：
CLB配置的话，我并没有发现有问题

,
Jerry Xu：
烧写的HEX文件
,
Jerry Xu：
可以确定是CLB环节出了问题，对于CCS编译CLB需要特别的设置码
,
Jerry Xu：
非常感谢您的帮助，问题找到了，CLB部分的函数需要手动添加到主函数中，我没有加入，导致没有编译
,
Susan Yang：
很高兴您能解决问题。关于CLB使用时cmd的问题，我也请教了同事，之后也会贴上相关的回复
