imx6q ar8031 网络ping不通

[小辉哥]

版主 你好，

 参考MCIMX6Q-SDB 设计一个板子，ar8031 现在ping不通，可以识别到，也可以ping通自己的IP，会出现错误帧；

这是什么原因导致的呢？请帮忙回复一下 。谢谢！

which BSP are you using?

You can try to connect your board to a router. Then ping the board's IP address from other PC which is connected to the same router.

If ping failed, please check the PHY is working properly. Check the supply voltage of your PHY chip, the reset pin of your PHY and so on.

Hi jim，

原因找到了是ar8031的1.1V不稳定导致的，外接一个1.1V到DVDDL，AVDDL就可以ping通了，这个是AR8031，LX脚走线不当吗？
