工具与软件：

您好！

我在 SDK 中根据 enet_l2_multi_channel_am243x-evm_r5fss0-0_freertos_ti-arm-clang 编译工程。

PHY 在演示中使用的是83826而不是83869。

问题是、

1.在演示项目中,只有83822而不是83826的配置。我在 gEnetPhyDrvs 中添加了83822、我不确定它是否正常。

2.对于 gEnetCpbBoard_am243x_EVM_EthPort、我不知道83826的扩展配置、因此我把它留空。

3.我在 mcu_sdk 中搜索时、出现了名为 ethphy_dp83826e.c 和 ethphy_dp83826e.h 的文件我想知道这些文件是否有演示、因为我只需连接到芯片。

导入设置

修改后的 enet_custom_board_config.c

e2e.ti.com/.../enet_5F00_custom_5F00_board_5F00_config.c

系统配置

e2e.ti.com/.../8154.example.zip

来进行 ENET 配置
