您好，DRA821U Champ！
据我所知、DRA821U 串行器/解串器包含4个通道。
客户不使用 Lane0、
Lane1和 Lane2用作 SGMII 端口、
对于 Lane3、他们希望根据需要禁用 USB3模式。
即使我在设备树中将 USB 节点更改为禁用、似乎也出现故障、但似乎正在发生一些事件、因此请告诉我如何才能完全禁用该功能。
在该用例中、USB3端口连接到外部5G 模块、
它们尝试根据需要禁用 USB3。
谢谢。
此致、
插孔
你好，Diwakar
我已从以下链接删除您分享的补丁。
因此、当前内核设置如下。

1.将通道3的主控制 MMR 设置为"未使用"。 这会从控制器断开 SERDES
[/报价]在 dtsi 中、您可以看到我们正在将 LANE3配置为未使用。
[/quote]3.将控制器设置为仅在 USB 2.0模式下运行。
[/报价]通过设置属性 仅 TI、USB2_ 在 dtsi 中、您已经这么做了。
您是否可以尝试使用 clean build、因为上述 设备树快照中的更改 正确、USB 应在 USB2.0中工作。

您在 USB3.0中共享的日志已启用、是因为我们建议您对 usb3.0禁用串行器/解串器配置进行了更改。

这些日志显示 USB 以3.0伏的
帮助共享您用于此目的的 dtb

为什么您最终将 USB 配置为3.0有助于共享 dtb 而不是 dtsi。
为避免混淆、请恢复整个补丁、而不是注释掉。
补丁应如下所示

您好！ 迪瓦卡尔
注释部分是为使用 USB 3.0而创建的部分、如 DTB 中所示、该部分被删除。
但当您查看下面的日志并观察它时、

在 您之前在 /cfs-file/__key/communityserver-discussions-components-files/791/k3_2D00_tgu.zip 共享的 zip 文件中
可以进行少量更改，将 dr_mode 更改为主机
DR_MODE ="主机"
除了上面建议的更改、您可以 在 Linux 中运行以下命令
devmem2 0x066000010 w 0x80000
断开您的模块、然后重新连接它
是否能够获得2.0版本的器件。

您好、Diwakar
我在 DTS 文件中将其修复为"dr_mode"。 但 USB2.0仍无法正常工作。
"devmem20x06000010 w0x80000"在执行此命令后、即使模块断开并再次连接、USB2也不可见。
