AM5718: 使用pru1支持了两路以太网，如何在生产过程中配置其mac地址

专家们好：

         如标题所述，我使用TI的am5718作为处理器，sdk版本：ti-processor-sdk-linux-am57xx-evm-04.03.00.05。因为是用于开发网络板，两个千兆以太网口外又用pru1实现了两路以太网口eth2和eth3，现在eth2和eth3已可以通信。板卡设计了spiFlash，现在可以在uboot阶段，通过setenv 命令分别设置了ethaddr，eth1addr,eth2addr,eth3addr,  启动后发现，仅两路cpsw支持的千兆以太网使用了ethaddr和eth1addr，eth2和eth3没有使用环境变量配置的地址。

        请问如何让eth2和eth3使用uboot阶段配置的eth2addr和eth3addr地址？

谢谢！

你好：

目前还没有人问过类似问题？看来有行业特定的方式解决，这个方法我不知道。
