器件型号：DP83826I 您好、TI 专家、
我们目前正在努力让 DP83826I PHY 与 Sitara AM243x 一起运行。
为了分步分析问题、我们尝试从在我们自己的硬件目标上运行的 AM243x SDK (V08.03.00.18)获取"enet_layer2_icssg"示例、我们在其中使用 DP83826I PHY。
我们修改了 example.syscfg 以匹配我们的硬件设计：
/**
* These arguments were used when this file was generated. They will be automatically applied on subsequent loads
* via the GUI or CLI. Run CLI with '--help' for additional information on how to override these arguments.
* @cliArgs --device "AM243x_ALV_beta" --package "ALV" --part "ALV" --context "r5fss0-0" --product "MCU_PLUS_SDK_AM243x@08.03.00"
* @versions {"tool":"1.12.1+2446"}
*/

* Import the modules used in this configuration.

接下来、我们在硬件目标上运行示例、应用程序中的日志看起来不错、但我们无法通过 PHY 看到任何通信：

我们看不到来自目标的任何通信(它应该回送所有接收到的帧)、但链路检测等似乎起作用。 我们在示例中稍微深入地看了一下，我们在 EnetUdma_rxCqIsr()函数中设置了一个断点，但从未调用过该断点。
我们在启动后立即进行了正确的 PHY 配置检查、以实现 PHY 寄存器转储：

我们感到奇怪的是、"自动协商"似乎被禁用-它应该通过自举引脚启用(请参阅寄存器0x0467中的自举锁存器)。
我们在 LinkUp 事件之后进行了额外的寄存器转储、现在他似乎正确启用了"自动协商"、但仍然无法进行通信。：

下面是另一个使我们困惑的点：为什么在 LinkUp 之后寄存器0x19中保留的位10设置为1？
您是否有任何提示、为什么沟通无法正常进行、以及我们可以在哪里进一步调查？
