hi, my designed xavier board，2 usb port, usb2-1 for otg function,another usb3( UPHY_RX6/TX6 and usb2-1), refer to “Tegra_Linux_Driver_Package_AGX_Xavier_Adaptation_Guide.pdf” modify dtb，hardware/nvidia/platform/t19x/galen/kernel-dts/common/tegra194-p2888-0001-p2822-0000-common.dtsi. usb3 abnormal.
，2 usb port, usb2-1 for otg function,another usb3( UPHY_RX6/TX6 and usb2-1)
請問你這個是在講什麼…? 為何兩個usb2-1 port?
板子引出2个usb口，一个是usb2.0，一个usb3，其中usb2.0口使用的是（USB0_DN/USB0_DP）,usb3.0口使用（UPHY_RX6_N/P和USB1_DN/DP）.
Hi,
ok, 所以是一個usb2-0 跟一個usb3-0+usb2-1.
你的device tree有跟著改嗎？ 預設的device tree是2個type C port, 那部份必須要先移除掉,並且改成你在用的

请帮忙确认一下dtb配置是否有问题？

請你把完整的dtb 用dtc tool轉回dts之後再附上來
另外, 請你用附上的. 不要用貼上的
tegra194-p2888-0008-p2822-0000.dts (358.7 KB)
请帮忙看看
麻煩先讀個文件好了 看起來xhci, xudc, xusb_padctl 都還沒改過
哪些地方没有修改？
hi WayneWWW, 我们设计的板子usb3口，通过GPIO22(这个口用作GPIO，输出高电平实现供电)，但是按照官方 Pinmux Changes教程，修改后烧入板子，查看状态不对：
There are some reference code to refer to.
tegra194-power-tree-p2888-0001-p2822-1000.dtsi
→ usb2-3 is using “vbus-supply = <&p2822_vdd_5v_sata>”
hardware/nvidia/platform/t19x/galen/kernel-dts/common/tegra194-fixed-regulator-p2822-1000.dtsi has the definition of “p2822_vdd_5v_sata” regulator.
vbus-supply 是不是添加到usb2-0? 一个是修改配置后的dts,一个是板子上dtc编译出来的
dtc-tegra194-p2888-0008-p2822-0000.dts (358.7 KB)
tegra194-p2888-0001-p2822-0000-common.dtsi (7.9 KB)
首先要先講一下… 我不認識你也不知道你的板子. 問我vbus-supply是不是加到usb2-0, 坦白說我不知道
如果你想要我能給出答案, 麻煩你把線路圖附上
如果是給USB1用的話那是usb2-1…
please set it to GPIO mode.
