T113 usb 转以太网烧脑的问题

[efancier]

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？

8125我记得是有内置delay的，delay配置删了试试看

[efancier]

@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。

[YuzukiTsuru]

@efancier 软件相同硬件也相同吗？估计问题不在delay上

[efancier]

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

@efancier 你的usb1口读取U盘成功啦？我的调试好久都不行

[efancier]

@jacky502 ，我U盘读写都是可以的，你出错的时候是什么提示？
