器件型号：PROCESSOR-SDK-AM64X 主题中讨论的其他器件：DP83869HM
我有一个带 AM64X 处理器的定制硬件。
我的软件是 Linux 内核5.10.41。
我有2个 DP83869HM PHY 连接到 ICSSG1-pru1和 ICSSG1-pru0
我正在使用 08.04.00.003中的 am65x-sr2-固件：
am65x-sr2-pru0-prueth-Fw.elf am65x-sr2-rtu1-prueth-Fw.elf
am65x-sr2-pru1-prueth-Fw.elf am65x-sr2-txpru0-prueth-Fw.elf
am65x-sr2-rtu0-prueth-Fw.elf am65x-sr2-txpru1-prueth-Fw.elf
我可以检测 MDIO 总线上2个 PHY 的链路 、但无法通过 MII 总线(RGMII)发送/接收数据。
我想器件树中的某些内容未正确定义、或者我使用了错误的固件。
当我尝试 ping 外部时、TX 计数器会增加、但 RX 计数器保持为0。
在另一台计算机上使用 tcpdump、我验证了硬件中的数据实际上没有发送。
