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

以下是产品线工程师的回复：

You can use u-boot to get the addressees from any media and then pass those on to the kernel. The kernel will then use these MAC address as the local-mac-address property and assign it. For this, please see the function "board_ti_set_ethaddr()" at location "board/ti/common/board_detect.c" in u-boot source code.

The function "eth_env_set_enetaddr_by_index()" sets the environment variable with a mac address. While booting up kernel, you can use aliases for the ethernet nodes and get MAC addresses from these environment variables.

You can use any non-volatile memory to store the addresses and read them from u-boot. Then you can use the above method to pass it on to the kernel.

文件系统本身位于非易失性存储器中（SD 卡或 eMMC）。您可能必须在其中创建一个单独的分区并使用该分区来存储 MAC 地址，或者您可以将其存储在文件系统本身中。然后您可以使用 u-boot 中的适当驱动程序读取该介质。

它可能很慢并且文件系统可能需要一些时间。如果有另一个分区，通常会更快。您可以根据您的用例来决定。

好的～
