器件型号： AM6422
主题： SysConfig 中讨论的其他器件
尊敬的团队：
代表我们的客户发帖。
我们在我们的定制电路板上使用 TI SDK 在 AM6422 上启用 ICSSG 以太网时遇到问题。
我们已对`k3-am642-evm.dts`进行了以下更改、简单地禁用了以太网 1/2 和多路复用器控制器、因为我们不使用它、并修改了引脚以匹配我们的 SysConfig 导出。

};我们目前正是 TI DP83867 链接到 icssg1-eth 并初始化以太网驱动程序的时间点、加载 Remoteproc 固件后、PHY 链路会按 LED 指示关闭、我无法启动它。
我们使用 thinlinux 预构建 fs、仅修改 DTB。
我们在 AM6422 EVM 上尝试了此图像、这些图像确实适用于 icssg。
此致、
Danilo
