器件型号：DP83TC812EVM-MC
主题中讨论的其他器件：DP83TC812R-Q1

您好！

我们使用 DP83TC812R-Q1芯片开发具有100Base-T1接口的电路板。
我们已使用载板检查此情况、如以下连接。

我们已经隔离了 DP83867ERGZR 芯片连接。

检测到链路。通过 MDIO、MDC 线路通信正常。
但我们无法执行 Ping 操作。
它显示*网络无法访问*
我已在下面附上了此问题的日志。

尊敬的 Santhoshwaran：

我注意到驱动程序无法读取 MDIO 地址。您能否改为尝试附加的驱动程序文件？

尊敬的 Melissa：

实际上我们加载了驱动程序、MDIO 地址为0。

DP83TC812_CS2_0_PHY_ID 0x2000a271 是 PHY ID 读取。
