[参考译文] PROCESSOR-SDK-J784S4：串行器/解串器 (MAC 端口 8) PLL 未锁定。

工具/软件：

您好、

我有一个基于 EVM 的定制板。

在 EVM 上、MAC 端口 1、3、4、5 配置为 QSGMII 并连接到 ENET 扩展板。

在此定制板上、MAC 端口 8 通过 SGMII 连接到 PHY 88M222x。

我想快速修复、所以我没有创建新的电路板、而是尽可能重复使用 j784s4evm。

我通读了移植指南、这是相应的修改：

1. 选择以太网端口接口类型

 }

2. 通过 SciClient 启用模块

用于启用 CPSW9G 模块、因此  无需更改

 3. Pinmux 设置

MDIO/MDC 引脚、因此无需更改

4. 以太网 PHY 初始化

PHY RESET 引脚在上电时复位、因此无需更改。

5. SerDes 配置

我重复使用 EVM SGSgmii、但设置 Board_Cfg。

 6. CPSW 时钟配置

没有变化。

 7. MAC 地址池

没有变化。

8. MAC 端口和 PHY 配置
