pipe 4 自动以太网是否需要进行任何额外配置? Re: TJA1120A 1000BASET1 Linux side configuration 你好@vikyhre ,
根据新的日志,1000BASE-T1 端似乎工作正常。检测到 TJA1120 PHY,链路速度为 1 Gbit/s,主/从状态正确,SQI 报告为 7/7。
然而,以太网接口统计信息仍然显示 RX 数据包为零,而 TX 数据包却在增加。这表明接收到的帧没有到达 Linux MAC/网络协议栈。
请重新检查 Linux 设备树中的 RGMII 时序配置。日志显示接口配置为“phy/rgmii”。如果您的电路板设计要求 PHY 提供内部 RGMII 延迟,则设备树通常应使用“rgmii-id”而不是普通的“rgmii”实例。RGMII 延迟配置不匹配会导致出现以下情况:PHY 链路已建立且 SQI 良好,但 Linux 无法成功接收数据包。
您能否在电脑端使用 Wireshark 检查一下,看看是否能看到 ECU 发送的任何帧?例如,在 ECU 上启动 eth0 后,请检查 PC 上是否捕获到来自 ECU MAC 地址的 ARP、IPv6 邻居发现或任何其他以太网帧。
同时,请在 ECU 端运行 tcpdump,并从 PC 端进行 ping 操作:
tcpdump -ni eth0 -e arp 或 icmp
如果没有捕获到 ARP/ICMP 数据包,并且 RX 计数器保持为零,则问题很可能仍然出在 MAC 到 PHY 的 RGMII 路径或其设备树定时配置中,而不是出在 1000BASE-T1 链路本身中。
顺祝商祺!
帕维尔 Re: TJA1120A 1000BASET1 Linux side configuration Pavel,正如你所说,我已将 CONFIG3,4 引脚连接到 RGMII-ID(根据 TJA1120A 数据手册 6.7.2,我尝试了 RGMII-ID 和 RGMII-ID (TX/RX))。同时将 phy-mode 设置为“rgmii-id”。 &cpsw_port1 {
status = "okay";
phy-mode = "rgmii-id";
phy-handle = <&cpsw3g_phy0>;
}; 这反映在 dmesg 中 [ 6.817790] am65-cpsw-nuss 8000000.ethernet eth0: configuring for phy/rgmii-id link mode 但是 ping 命令仍然不起作用。 acs@a-tract-10:~$ ping 192.168.1.100

谢谢你的更新。这项新成果非常有用。
我们现在可以假设 RGMII-ID 有效。
一个重要的观察结果是,来自 PC 的 ARP 请求是 VLAN 0 优先级标记帧:
以太网类型 802.1Q,VLAN 0,以太网类型 ARP
而 ECU ARP 回复是未标记的 ARP 帧。请检查 PC 接口、桥接、VLAN、QoS 或驱动程序/卸载配置是否需要带标签的流量,或者未带标签的 ARP 回复是否被过滤或未与 ARP 请求关联。
注意:以下 Linux 命令仅供参考,可能需要根据您的具体 Linux 发行版、网络接口名称和系统配置进行调整。
请捕获PC端的流量:
sudo tcpdump -eni -vvv '(arp or icmp or vlan)'
然后再次开始 ping 命令。
如果 PC 捕获未显示来自 ECU MAC 地址 `64:1c:10:1c:06:e2` 的 ARP 回复,则问题仍然出在 ECU 到 PC 的传输路径或媒体转换器路径中。
如果 PC 捕获显示 ARP 回复,但 PC 仍然报告“目标主机不可达”,则问题很可能出在 PC 端的 Linux 网络/VLAN/过滤配置中。
作为额外的隔离测试,请尝试在电脑上添加静态 ARP 条目:
sudo ip neigh replace 192.168.1.100lladdr 64:1c:10:1c:06:e2 dev nud permanent
然后重复 ping 命令,同时捕获两端的流量。
顺祝商祺!
帕维尔 Re: TJA1120A 1000BASET1 Linux side configuration 你好@vikyhre ,
所以问题似乎出在ECU到PC的传输方向上:
ECU MAC TX 路径,
RGMII TX MAC 和 TJA1120A 之间的时序/延迟配置,
TJA1120 传输路径,
媒体变流器接收路径,
或者可能是 RGMII 接口上的信号完整性/板级时序问题。
CONFIG 引脚连接定义了 RESET 后的默认配置,但当 NXP TJA11xx Linux 驱动程序处于活动状态时,PHY 可以通过 MDIO 根据 Linux 设备树重新配置。所以,用销钉捆扎实际上没有任何效果。
1.如果只有一个方向受到影响,则测试适用的方向性 RGMII 延迟变体可能很有用,例如:
phy-mode = "rgmii-id"; /* RX 和 TX 内部延迟 */
phy-mode = "rgmii-rxid"; /* 仅接收内部延迟 */
phy-mode = "rgmii-txid"; /* 仅发送内部延迟 */
phy-mode = "rgmii"; /* 无 PHY 内部延迟 */
另外,请确保所选的 Linux phy 模式与您的硬件设计中预期的 MAC/PHY 延迟所有权相匹配。
2. 同时,我还建议从 ECU 向 PC 发送流量,并检查 RGMII TX 引脚上是否有活动。例如,您可以运行:
ping *I eth0 192.168.1.101
并用示波器监测 MAC 和 TJA1120A 之间的 RGMII TX 信号,特别是
TXC、 TX_CTL、 TXD[3:0]。
如果 Linux 尝试发送数据时这些引脚上没有任何活动,则问题可能仍然出在 PHY 之前的 MAC/驱动程序/配置路径中。如果 RGMII TX 引脚上有活动,但在 PC 端未观察到有效帧,则应重点关注 RGMII TX 时序、延迟配置、信号质量或媒体转换器接收路径。
3.请重复静态 ARP 测试,同时强制 PC 使用预期接口:
sudo ip neigh replace *92.168.1.100lladdr 64:1c:10:1c:06*e2 dev eno1 nud permanent
ip 邻居*显示 192.168.1.100开发 eno1
ip rou*e 获取 192.168.1.100
sudo tcpdump -*ni eno1 -vvv '(arp 或 icmp)'
ping *I eno1 192.168.1.100
注意:以上 Linux 命令仅供参考,可能需要根据您的具体 Linux 发行版、网络接口名称和系统配置进行调整。
如果静态 ARP 条目有效,PC 就不再需要发送 ARP 请求。它应该直接向ECU MAC地址发送ICMP回显请求帧。这些帧至少应该在 PC 端的 tcpdump 中可见。如果即使 PC 端的 tcpdump 也未显示出站 ICMP 帧,请检查 PC 的路由、邻居表和接口选择。
如果在 PC 端可以看到传出的 ICMP 帧,但在 ECU 端看不到,则说明 PC 到 ECU 方向的单播流量仍然无法完全正常工作。如果 ECU 接收到 ICMP 帧并生成回复,但 PC 没有接收到回复,则问题仍然存在于 ECU 到 PC 的传输方向上。
顺祝商祺!

谢谢你的更新。这是个好消息。很高兴它现在对你有用。
我从你的日志中没有发现任何可疑之处——没有发现任何明显的缺失。作为最后的健全性检查,您还可以反向运行 iperf3 测试。
关于您提到的 `rgmii-txid`:这是一个 Linux 通用设备树 `phy-mode` 值。它不一定需要在 TJA1120A 数据手册中使用完全相同的 Linux 命名。TJA1120A支持 RGMII TXC 和 RXC 时钟路径中的独立延迟配置——请参考寄存器 RGMII_TXC_DELAY_CONFIG 和 RGMII_RXC_DELAY_CONFIG。此外,引脚绑定本身仅支持有限的配置。
如果我之前的回复帮助您解决了问题,请将其标记为解决方案,以便其他用户更容易参考。
顺祝商祺!
帕维尔 Re: TJA1120A 1000BASET1 Linux side configuration 感谢你的见解,帕维尔。 我们让它运行起来了 我担心的是,TJA1120A 数据手册中没有提到“rgmii-txid”,它只是将延迟时间缩短到 TX_CLK。但是“rgmii-txid”对我们仍然有效。请澄清一下。我已将 DT 中的值更改为“rgmii-txid”,因为您提到 DT 可以覆盖 CONFIG_PIN 绑定。供您参考,PIN 绑定目前为 RGMII-ID(根据数据手册,仅在 RX 上延迟)。 我用 Windows 电脑 ping ECU 时,这是 ECU 端的 TCP 转储。 root@am62axx-evm:~# tcpdump -eni eth0 -vvv '(arp or icmp or vlan)'
