      自己做的T113板子,Buildroot编译的系统,在芒果派 MQ dual 上面运行,使用USB转以太网,RTL8152, RTL8153 或者 ax1189 都可以正常运行,同样软件,同样的USB转以太网 dongle, 连接到自己的板子上就有问题,获取不到IP地址,提示tx timeout
      已经排查过的:
      1:电源,使用同样的电源,芒果派 MQ dual 可以运行没问题
      2:USB转以太网 dongle,同一个连接到芒果派 MQ dual 可以运行没问题
      3:USB口,USB0和USB1是一样的现象
      4:USB布线,做了阻抗匹配,U盘读写没有问题
      5:USB接口电源,添加滤波电容没有作用

      以下是打印的消息,tx timeoute 设置加大10倍都没有帮助,大神们过来围观一下?

          @yuzukitsuru , 谢谢回复, 软件用的是同一张 TF卡,所以配置参数应该是一样的,硬件测试用的也是同一个USB转网络的Dongle, 自己做的板子跟对比的板子区别在USB 主机这一端,按说不会涉及到 8125里面的delay, 回头还是试试看有没有影响。

            @efancier 软件相同硬件也相同吗?估计问题不在delay上

              @yuzukitsuru , 软件和USB 转以太网Dongle 是完全一样的。
