am3359 rtl8211cl 只能收包不能发包,波形正常.

Other Parts Discussed in Thread: AM3359

TI工程师您好:

    环境: ti_sdk_7.00.00.  am3359 自定义板子 rtl8211cl网卡 u-boot

    问题, u-boot 和 linux下,都只能收包,却发不出去包,环回测试也收不到自己发的东西.示波器观察波形正常.

        u-boot和linux下,ping请求发不出去,但debug或tcpdump能够捕获网络中的数据.网络中的PC捕获不到板子的数据包.

    请帮忙判断是哪个寄存器配置的不正确或其他问题?

    万分感谢!
