Hi:

Is there any document about “PLATFORM ADAPTATION AND BRING-UP GUIDE” (document ID DA_07839-001" for R32.2.

I need the USB adaption example in it for 32.2.

so far, I modify the dts

original =>
xusb@70090000 {
phys = <&tegra_padctl_uphy TEGRA_PADCTL_UPHY_UTMI_P(2)>,
<&tegra_padctl_uphy TEGRA_PADCTL_UPHY_USB3_P(1)>,
<&tegra_padctl_uphy TEGRA_PADCTL_UPHY_UTMI_P(1)>,
<&tegra_padctl_uphy TEGRA_PADCTL_UPHY_USB3_P(0)>,
<&tegra_padctl_uphy TEGRA_PADCTL_UPHY_UTMI_P(0)>,
<&tegra_padctl_uphy TEGRA_PADCTL_UPHY_UTMI_P(3)>,
<&tegra_padctl_uphy TEGRA_PADCTL_UPHY_USB3_P(2)>;
phy-names = “utmi-2”, “usb3-1”, “utmi-1”, “usb3-0”, “utmi-0”, + “utmi-3”, “usb3-2”;

New =>
phys = <&{/xusb_padctl@7009f000/pads/usb2/lanes/usb2-0}>,
<&{/xusb_padctl@7009f000/pads/usb2/lanes/usb2-1}>,
<&{/xusb_padctl@7009f000/pads/usb2/lanes/usb2-2}>,
<&{/xusb_padctl@7009f000/pads/usb2/lanes/usb2-3}>,
<&{/xusb_padctl@7009f000/pads/pcie/lanes/pcie-6}>,
<&{/xusb_padctl@7009f000/pads/pcie/lanes/pcie-5}>,
<&{/xusb_padctl@7009f000/pads/pcie/lanes/pcie-3}>;
phy-names = “usb2-0”, “usb2-1”, “usb2-2”, “usb2-3”, “usb3-0”, “usb3-1”, “usb3-2”;

Could somebody help?

And I saw a discussion out the NV forum,
It mentions about ODMDATA in p2371-2180-devkit.conf.
Should I take care of it?

Hi,
Please refer to example of TX2:
[url]https://devtalk.nvidia.com/default/topic/1057885/jetson-tx2/usb-not-working-in-jetson-tx2-r32-2/post/5364464/#5364464[/url]

And modify xusb_padctl@3520000 and xhci@3530000 accordingly. ODMDATA is specific to TX2. Not required to modify it on TX1.
