[参考译文] AM625：以太网备用引导模式

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1493615/am625-ethernet-backup-boot-mode

工具/软件：

我们有一个使用 AM6232的定制电路板、RMII 模式下的以太网 PHY 为 Micrel XZ8041。

我已 从 ti-u-boot-2024.04创建了所需的3个文件、并将其复制到 DHCP/TFP 服务器、该服务器通过 USB 以太网端口(即专用端口)连接到 AM62。

在加电时、我可以看到 tiboot.bin 的初始 TFTP 工作并且 SPL 会执行。

尽管看到 PHY 被检测到并且链路有效、但我看不到  BOOTP 广播的任何 TX 输出。

您是否可以建议我查看一些区域以尝试诊断 TX 为什么没有将其发送到以太网输出？

已附加引导日志。

谢谢你。
