你好
我正在使用 Linux DSA 通过 SPI 将一个 SJA1110AEL 交换机连接到 Microchip PolarFire SoC 上 sja1105驱动程序，通过 SPI 将 SJA1110AEL 开关连接到 Microchip PolarFire SoC：
https://github.com/linux4microchip/linux/tree/linux-6.12-mchp%2Bfpga/drivers/net/dsa/sja1105
交换机配置为 SPI 启动模式（BOOT_OPTION=11），静态配置上传看起来很成功。

- CPU 端口 (SGMII) 启动正常。
- 我可以从连接到 RJ45 100BASE-TX 端口的笔记本电脑接收 ARP 数据包。
- 板上的 tcpdump 确认来自笔记本电脑的 ARP 请求。
- 当从主板发送（ping/arping）时，笔记本电脑不会收到任何东西。
- 笔记本电脑 tcpdump 未显示来自主板的 RX 数据包。
我的问题是
- 要使 TX 流量在 SJA1110 DSA 端口上正常工作，是否需要任何额外的运行时 MAC 配置/转发/路由表设置？
- 是否可以预期 100BASE-T1 PHY 在此驱动程序树 中仅作为 通用条款 45 PHY 出现 ？ 当前的 Linux 6.12 Microchip 树中是否缺少专用 BASE-T1 PHY 驱动程序？
为了进行测试，我尝试在两个 T1 端口之间进行直接环回 (T1-1<-> T1-2) 之间的直接环回，方法是连接：（TRX_1_P<->TRX_2_P 和 TRX_2_P<->TRX_2_N ）。
SJA1110 BASE-T1 PHY 是否需要为链路训练进行明确的主/从配置？

硬件表带配置：
- 全部 PHY_MS引脚均为低电平（从属模式）。
- PHY_AUTO_MODE= 高
- AUTO_POL_DET= 高电平
- PHY 地址从 0x09.
没有 T1 链路的原因会不会是两个 PHY 都绑定为 SLAVE，因此没有用于链路训练的主时钟源？
有关以下方面的任何指导：
- 正确的 T1 启动、
- 主/从配置、
- 或预期 PHY 驱动程序支持
将不胜感激。

-- 安库尔
你好@Ankur_pixl、
感谢您一次性分享所有细节。
请在下面找到您问题的答案。
Q1.要使 TX 流量在 SJA1110 DSA 端口上正常工作，是否需要任何额外的运行时 MAC 配置/转发/路由表设置？
A1.是的，请见下文。
Q2.100BASE-T1 PHY 在此驱动程序树中是否只能作为通用第 45 条 PHY 出现？当前的 Linux 6.12 Microchip 树中是否缺少专用 BASE-T1 PHY 驱动程序？
A2.A2.
Q3.为进行测试，我尝试在两个 T1 端口（t1-1<-> t1-2）之间直接环回，方法是连接：（TRX_1_P<->TRX_2_P 和 TRX_2_P<->TRX_2_N ）。
A3：是的，没错。
Q4.SJA1110 BASE-T1 PHY 是否需要为链路训练进行明确的主/从配置？
A4.是的，100BASE-T1 需要明确的主/从设置。仅供参考，驱动器中的"AUTO" 选项通常意味着"按照引脚捆绑" 。 要实现有效链接，必须通过硬件捆绑或 PHY 配置，将一个 PHY 配置为 MASTER（主设备），另一个 PHY 配置为 SLAVE（从设备）。
根据日志和 DT，交换机初始化和 PHY 绑定看起来是正确的。
如果 Linux 中没有配置网桥，就会出现 RX 可以工作而 TX 不能工作的情况。在 DSA 中，CPU 端口和用户端口之间不会自动转发流量。 DSA 交换机的行为类似于硬件交换机，但除非显式创建了网桥或 VLAN 配置，否则 Linux 不会在端口之间启用转发功能。
请创建一个网桥，同时连接 CPU 端口（eth0）和用户端口（rj45）：
ip link set eth0 up
ip link set rj45 up
ip link add br0 type bridge
ip link set br0 up
ip link set eth0 master br0
ip link set rj45 master br0
ip addr add 192.168.1.2/24dev br0
顺祝商祺！
帕维尔
您好，
我试过做同样的事情，但仍然没有看到笔记本电脑从
板上收到任何数据包。以下是我遵循的具体步骤：
-------------------
ip link set eth0 up
ip link set eth0 up
ip link set rj45 up
ip link add br0 type bridge
ip link set br0 type bridge
ip link set br0 up
ip link set rj45 master br0
ip addr add 192.168.1.1/24dev br0
ping 192.168.1.2
-------------------
为了提供更多信息：RJ45 连接器已返工，芯片 TX 对的 P/N 端口与 RJ45 连接错误，这也可能是造成问题的原因。但是，链接总是会出现。
有什么我遗漏的吗？我附上了与 ETH 和 PHY 相关的内核配置。请检查是否有遗漏。

我还尝试用 T1-1 和 T1-2 进行 100BASE-T1 环回，将 T1-1 设置为 PHY_MS = 1（主站），T1-2 设置为 PHY_MS = 0（从站）。我调出了两个界面，但链接始终没有出现。这在意料之中吗？我错过了什么？环回是双绞线（P/N）上的简单有线连接。

ip link set eth0 up
ip link set rj45 up
ip link set t1-1 up
ip link set t1-2 up
-------------------
你好@Ankur_pixl、
不知怎么的，你漏了一行：
ip link set eth0 up
ip link set rj45 up
ip link add br0 type bridge
ip link set br0 up
ip link set eth0 master br0
ip link set rj45 master br0
ip addr add 192.168.1.1/24开发周期
内核配置似乎正确。
关于 T1
100BASE-T1 的简单布线连接应该可以正常工作，我一直使用这种连接方式。是否使用 PHY_ADDR* 引脚绑扎？
请分享：
ethtool t1-1
ethtool t1-2
dmesg | grep -iE"t1-|phy|sja1105" 在链接启动之后
顺祝商祺！

是的，我确实使用了 PHY_ADDR 带，PHY_ADDR[4:0] 设置为 5'b010001。( 0x09 至 0x14 ) 与https://github.com/nxp-auto-linux/linux/blob/810f396375526c11989bd1a296d2f9959de9392f/arch/arm64/boo...和 S32G-VNP-RDB3 原理图相同。

你好@Ankur_pixl、
感谢您的更新 - 目前，我认为我们最好从头开始调试，使用最小的确定性设置，因为我们现在有几个相互影响的变量（DSA 拓扑、网桥行为和 PHY 访问路径），我们需要隔离 RJ45 问题是软件（Linux/DSA/网桥/VLAN）问题还是硬件（TX 对/磁性元件）问题。
从你最初的描述中，我们可以看出一个清晰的症状模式：
- RJ45 RX 正常工作（可以看到来自笔记本电脑的 ARP 请求）。
- RJ45 TX 不能（笔记本电脑看不到板上的任何框架）。
- 100BASE‑T1 仍处于关闭状态，目前我们没有足够的证据来得出结论，这是否与配置/管理路径有关，还是与物理层/训练问题有关。
这是第一步：
第 1 步 - 在不使用任何桥接器的情况下确认 RJ45 上的基本 TX
ip link set eth0 up
ip link set rj45 up
# 重要：移除其他设备上的 IP 以避免混乱路由
ip addr flush dev eth0
IP 地址 flush dev rj45
IP 地址 flush dev br0 2>/dev/null
# 将 IP 直接接入 RJ45 DSA 端口
ip addr add 192.168.1.1/24dev rj45
# 显示路由和地址以保持理智
ip addr show rj45
ip route show
# 产生流量
arping -I rj45 192.168.1.2
ping -I rj45 192.168.1.2
同时，在板上捕获
tcpdump -i rj45 -e -nn arp 或 icmp
笔记本电脑
tcpdump -i -e -nn arp 或 icmp
顺祝商祺！
帕维尔
你好，
，我还发现 eth0 链接没有显示 RUNNING，这会是问题之一吗？在进行 PING 时，RJ45 的 txbytes 会增加，但 eth0 发送的所有信息都会被丢弃。

您好
1.)我尝试了同样的测试，还检查了其他一些东西来验证问题。CPU 端口 (p04) 和 RJ45 之间似乎没有编程 L2 转发路径。

这是配置问题吗？
-- 安库尔
你好@Ankur_pixl、
感谢您提供的详细日志。请随时纠正我的解释。
您的最新结果非常有用，因为它们表明这很可能不再是一个单纯的桥梁问题。
对于 RJ45 直接 L3 测试（IP 直接分配到 rj45，无网桥），Linux netdev TX 计数器会增加，但 RJ45 端口的硬件交换机出口计数器仍为 0（`n_txfrm = 0`，`n_txbyte = 0`）。同时，RJ45 上的入口计数器也会增加，这表明前端 PHY/链路正在正确接收帧。
T1 回环结果也指向同一方向：两个 T1 端口都成功链接，因此 PHY 培训本身似乎有效，但流量仍无法通过。
这两种情况的共同点是 CPU/主控路径：
- `eth0` 保持 `NO-CARRIER`
- `eth0` 保持 `state DOWN`
- MACB TX/RX 硬件计数器保持为 0
- `eth0` 的 TX 丢弃数据包增加
由此看来，主要问题是 SoC MAC (`eth0`)和 SJA1110 CPU 端口 (p04) 之间的 CPU 导管路径，而不是前 RJ45 或 T1 PHY 端口本身。
换句话说，交换机侧端口可以启动，但面向主机的 SGMII/CPU 端口数据路径似乎无法运行。
在现阶段，我建议将重点放在 SoC MAC / PCS / SGMII 的 "eth0 "配置以及相应的 CPU 端口配置上，而不是进一步进行桥接实验。
请分享：
1. ethtool eth0
2. ip-d link show eth0
3. 连接到交换机 CPU 端口的 SoC MAC/PCS/SGMII 端的完整设备树片段
4. SoC 端任何可用的 PCS/SGMII 链接状态信息
eth0` 从未达到 RUNNING / carrier-up（运行/载波启动）是一个强有力的指标，很可能与流量故障有关。
我再次查看了你的 DT 片段，设备树的 DSA/SJA1110 部分在逻辑上看起来是一致的：
-MAC0 配置为 “sgmii”，具有固定的 1 Gbps 全双工链路-SJA1110 CPU 端口也被配置为 “sgmii”，带有固定的 1 Gbps 全双工链路
——内部 PHY 端口映射看起来也正确
因此，目前我看不出这个片段本身存在明显的 DSA DT 错误。
然而，仅凭这个 DT 片段并不能证明 SoC 端 SGMII/PCS/SerDes 通路确实在运行。根据您的计数器，交换机 CPU 端口在交换机一侧似乎处于活动状态，但 `eth0` 仍处于 `NO-CARRIER` / DOWN 状态，没有真正的 MAC RX/TX 流量。
这表明面向 SoC 的 SGMII/PCS/SerDes 路径（或其低级初始化）存在问题，而不是前面的 RJ45 或 T1 端口。
能否请您分享完整的 MAC0 / PCS / SerDes 相关配置，以及初始化 SGMII 通道的任何引导加载程序/底层配置？
顺祝商祺！
帕维尔
你好@PavelL
是的，在仔细查看原理图后，我发现从 SoC 到交换机的 SGMII TX P/N 线路被调换了。此外，相同的 SGMII 线路连接到了另一个端点，导致以太网链路无法连接。
我们目前正在修复这些问题，并将向您提供最新结果。
