您好专家：
我使用的是 RTOS SDK 07.03和 EVM 板。
我们通过 RMII 接口连接 CPSW2G 端口1和 bcm89836 phy、并通过 MDIO C45协议配置 phy。 将 TDA4板直接连接到 PC、发现无法 ping PC。 通过 ifconifg、发现问题是由于 Mac 上没有 Rx 导致的。 设置 Mac loopback、ifconfig 仅具有 TX、无 Rx、这应该是 Mac 端的问题
我打开了 Mac 环回、在对 PC 执行几次 ping 操作后、ifconfig 如下所示：
寄存器转储如下所示：
期待您的回复
我将提供更多文件 dts 和主 c 文件

您好、Gaston、
首先、我的侧没有明确说明、
当前的达芬奇 MDIO 驱动程序尚不支持 c45子句。 您必须修改 phy 读/写函数以与 c45 phys 兼容。
您能否交叉检查 phy 中设置的 TX 和 Rx 延迟。 "TI, Rx-interne-delay"是 TI 特有的属性，不适用于 Broadcom PHY。 您能否交叉检查自举延迟。 默认情况下、Mac 期望在 phy 中配置 Rx 延迟、在 Mac 中配置 Tx 延迟。
编辑：您能否告诉我如何设置 MAC 环回？
此致、
Tanmay
当前的达芬奇 MDIO 驱动程序尚不支持 c45子句。 您必须修改 phy 读/写函数以与 c45 phys 兼容。
继电器：我已移植最新的 DaVinci_MDIO.c，MDIO 读写与 c45 PHY 是正常的
您能否交叉检查 phy 中设置的 TX 和 Rx 延迟。 "TI, Rx-interne-delay"是 TI 特有的属性，不适用于 Broadcom PHY
中继：代码不分析此参数。 测量波形后、RMTXD 正常、但 RMRXD 根本没有波形。 至於延误，我会尽快与本公司联络
您能告诉我如何设置 MAC 环回？

您好 Tanmay Patil：
让我提供我们硬件电路设计的原理图。 它看起来非常奇怪。 我们使用 RMII 接口、但 RGMII TD2/3和 RGMII RX2/3都连接到物理芯片1588功能。 请对此进行评估、硬件是否存在重大问题？ 如果出现问题、应如何配置 RGMII TD2/3和 RGMII RX2/3的引脚、以使其不受影响。 我们的硬件中间没有连接电阻器、它直接连接到 Mac。 请评价此问题
仍然存在一个巨大的问题、我们的 RMII1_RX ER 未连接、这必须影响 MAC Rx、是否可以通过配置寄存器更改此行为以使 RX 正常工作？
