[参考译文] AM2431：AM2431连接到单个开关 IC 设置问题

Larry、您好！

您是否尝试过修改 SysConfig 设置、以在 pinmux 中禁用 MAC 端口2和禁用 RGMII2？

如果您已经进行过尝试、但仍然无法正常工作、您能否共享您的 syscfg 设置、这样我们就可以清除我们对配置问题的怀疑。

否则、您能否尝试将其禁用并尝试一次。  

此致、

Shaunak

Larry、您好！

您是否有可能共享 MacPort 和 PHY 寄存器转储以查看我们在运行时使用的配置。 我将使用 Enet Layer2 CPSW echo 示例查看您的 syscfg、该示例具有类似的配置(仅1个端口)。

同时、您能否确认您正在写入的新驱动程序文件是否已按预期进行编译并链接到主应用程序？ 无法达到新的驱动程序代码是奇数。  

此致、

Shaunak

尊敬的 Shaunak：

在哪里可以 转储  MacPort 和 PHY 寄存器？

当我尝试在 syscfg 中的"Enet (CPSW)-> Pinmux config -> CPSW pinmux 0"下禁用 MDIO/MDC 信号时、我可以确认我的 PHY 驱动程序已链接。 在该配置下运行程序后、我观察到程序确实到达了链接到函数指针的 PHY 驱动程序

bool (*isPhyDevSupported)(EnetPhy_Handle hPhy, const EnetPhy_Version *version);。

但是,当我在 CPSW pinmux 0中启用 MDIO/MDC 时,程序不执行*isPhyDevSupported。 这真的令人费解。

此致、

拉里

尊敬的 Shaunak：

下面是我找到的 CPSW0_NUSS 寄存器。 这是您需要的吗？

我还发现我的 PHY 驱动程序未绑定、这似乎是由 enetphy.c 中的特定代码段引起的。 在第313行、我注意到我的程序在到达此行时确定 MDC/MDIO 不活动、因此它不输入"if"语句。 因此、不会执行 EnetPhy_bindDriver 函数、因此未使用我的 PHY 驱动程序。 可能的原因是什么？
