[参考译文] TDA4VM：[TDA4] Marvel T1以太网 phy (88q2220)不适用于 CPSW9G

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1085435/tda4vm-tda4-marvel-t1-ethernet-phy-88q2220-does-not-work-for-cpsw9g

各位专家：

我们为 CPSW9G 交换机使用两种不同的 T1以太网 PHY， 为 DP83TC811使用 RGMII5 (第22条)，为88Q2220使用 RGMII2 (第45条)

我们可以通过 RGMII5从 eth1接口获取 DHCP IP，但 RGMII2 DHCP 客户端出现故障。

因此，我尝试从 TDA4 RGMII5和 RGMII2转储物理以太网帧寄存器，状态如下所示

遵循上一个日志...  

与正常帧(RGMII5)相比 ，RGMII2 不会获得 任何单播帧和匹配的比例调节器

我不知道调试此问题。

有人可以发表一些评论吗？

非常感谢
