器件型号：PROCESSOR-SDK-AM62A 主题中讨论的其他器件：SK-AM62A-LP
工具/软件：
您好 TI 专家：
我正在使用 ti-processor-sdk-linux-edgeai-am62axx-evm-09_01_00_07 和 一个基于电路板的 SK-AM62A-LP。
我 在 DTS 文件中配置两个以太网端口、 端口 1 连接到 phy 芯片、 端口 2 连接到 MAC2MAC 模式。
DTS 文件“ k3-am62a7-sk.dts “中与以太网配置相关的代码片段更改如下：
aliases {
serial0 = &mcu_uart0;
serial1 = &wkup_uart0;
serial2 = &main_uart0;
mmc0 = &sdhci0;
mmc1 = &sdhci1;
ethernet0 = &cpsw_port1;
ethernet1 = &cpsw_port2;
spi0 = &ospi0;
};
&main_pmx0 {
main_mdio1_pins_default: main-mdio1-pins-default {
pinctrl-single,pins = <

构建 Linux 和 u-boot 并将所有映像烧录到 EMMC 后、 我在启动电路板时从 am65-cpsw-nuss 驱动程序收到了一条错误消息：

请帮助确定我的配置有什么问题
