同一块ok6410核心板，分别接两块底板启动输出结果不一样。

两块底板一块有问题不能启动CE6（称为“问题板”） 一块可正常启动CE6（称为“正常板”）

现用同一块装有linux2.6.28的核心板先后与“问题板”和“正常板”相配看启动信息。“问题板”表现为有usb相关的错误信息输出
而“正常板”却没有。
请斑竹，大虾们分析下“问题板”的问题到底出在哪里 ？？？？“问题板”和“正常板” 是同时在3月份从飞凌买的。

拔掉开发板usb和pc的连接线就没有了。
不是问题。
至于wince的问题。也可以跟帖发出来。

我没有插usb的链接线啊。host  和otg 都没连    如何解释 同一个核心板一块底板能启动CE 一块底板不能启动
