一个ARM与WINDOWS网络连接的问题

kevincoxzq 2012-03-25 02:22:30

在做ARM板与PC机通信，PC机是WINDOWS 7 系统，ARM烧的linux2.6核，用串口加超级终端来进行操作。ARM的IP是192.168.1.6，PC机IP设置为192.168.1.7.然后用网线连接起来，网线就是普通家用上网的网线。连接起来之后用ping命令总是无法ping通，PC机上pingARM的IP显示无法访问目标主机，ARM上pingPC机的IP则一直没有反应。

请问设置ARM于PC的网络连接是不是只要设置IP在同一网段就可以了？还需要做一些其他的工作么？或者说是要用交叉网线才可以么？请教各位高手

要用交叉网线才行吧
