尊敬的 TI 团队:
我正在 LP-AM243上使用 enet_lwip_cpsw_am243x-lp_r5fss0-0_freertos_ti-arm-clang 示例
我们的 AM243x ALV 和 DP83869定制电路板上的1Gbit 存在问题。 由于我切换到了 LP AM243x、并且在执行 enet_lwip_cpsw_am243x-lp_r5fss0-0_freertos_ti-arm-clang 时、我具有与定制电路板上相同的行为:
1Gbps 连接无法正常工作
-我没有从 DHCP 服务器获得 IP 地址
-我在 Wireshark 中看不到相应的流量

100 Mbps 连接工作正常
-我将网络适配器的驱动程序设置更改为固定为100 Mbps ,而不是自动协商
-板设置链路与100 Mbps
-我看到流量,得到 IP 地址,一切正常

不确定 LP-AM243的确切版本、有一个标签"PROC109A (001)"
MCU+ SDK AM243x 10.00
我还偶然发现了具有类似问题的各种不同线程、但它们似乎都使用的是旧版本的 SDK、但更新的电路板。 对于这个主题有什么想法在我的情况下可能会有什么问题?
