这个是PHY没有找到，PHY的供电、地址是配置正确吗，确保RMII几个时钟要有的，用是的哪个SDK，是否需要在驱动里配置PHY ID ?

SDK 可以先下载吗？

感谢博主的分享，已在T113下把CAN调通，谢谢

有大佬在mangopi t113-s3上运行成功吗，之前用mangopi提供的SDK可以生成image，也可以烧录成功并运行，但是，今年再次生成的image就运行不了，console未没有任何提示，板卡上的一个状态LED灯也不亮（uboot运行后，该LED灯会亮），搞不清楚是什么原因，头疼……

请问，这个问题解决了吗？
有大神解决了该问题吗？

@jinxiangwzh 在 全志芯片Tina Linux 修改 UART 引脚、UART端口 中说：

学习了，感谢您的高质量输出

dmesg 有什么信息？驱动正常吗？

谢谢，在H6上，用上面的命令配置后，可以正确的输出波形。

向大神学习
