Hi,
I’m trying a board custom from tx2, using L4T 32.2.1 package with sample rootfs 32.2.0.
With nothing changed and flash default images, I read below error msg in kernel boot log:
tegra-xusb-padctl 3520000.xusb_padctl: failed to setup XUSB ports: -517
attached full kern.log. I’m new to tx2, it looks having a complicated BSP system, please kindly help me start on it.
thanks

Hi,
You may need to modify device tree per your custom board. Please refer to

Hi,
I made changes according to the link, also needs to change odmdata, now I’m seeing:
Please complete system configuration setup on /dev/ttyGS0 to proceed…
I don’t have a monitor yet and I don’t want to debug hdmi issue now, is there any method to force it to use /dev/ttyS0 to do the configuration?
thanks
Hi,
You may login through ssh and run xxd to check correctness of device tree. Here are some debug tips.
I tried xxd
nv@tegra-ubuntu:~$ xxd /proc/device-tree/xhci@3530000/phy-names
00000000: 7573 6232 2d30 0075 7362 332d 3100 usb2-0.usb3-1.
I set odmdata to 0x2090000, config usb2-0 and usb3-1 only.
Now I see below message in kernel log:

any suggestion?
Hi,
It looks not right that you don’t configure ports. Below is an example from the post
ports {
usb2-0 {
status = "okay";
mode = "otg";
vbus-supply = <&vdd_usb0_5v>;
nvidia,oc-pin = <0>;
};
usb2-1 {
status = "okay";
mode = "host";
vbus-supply = <&vdd_usb1_5v>;
nvidia,oc-pin = <1>;
};
usb3-1 {
nvidia,usb2-companion = <1>;
status = "okay";
};
};
You may remove nvidia,oc-pin if you don’t use it, and set vbus-supply, nvidia,usb2-componion. For a USB3 type A, it has two pin USB2, four pin USB3, and a VBUS pin.
Enumeration issues are seen if VBUS is turned on too early. You may also check this.
Hi,
I do configured the ports, not pasted here. The usb3-1 port configuration is just same as you posted.
usb3-1 pin assignment on our custome board are same as official tx2.
Hi,
Please refer to the adaptation guide for further checking:

I commented out overlays in plugin manager dts file and xhci settings in c03 base dts, also set odmdata to 0x2090000, now I don’t see error message of usb at kernel booting, but usb3-1 seems still not working:

not sure what else should configure to make it work
Hi,
The device tree shows usb3-1(PEX_RFU, G39 G40 D39 D40) is configured to ‘enable-xusb-on-uphy-lane1’. And usb3-1 and usb2-1 is a type A port. VBUS pin is A18.
If above meets your hardware design, the device tree looks good. Are you able to try other USB3 devices such as USB3 pendrive?
Or maybe re-work VBUS pin out, connect to a power supply and try to turn it on/off to check if enumeration happens.
Hi,
usb3-1 pin is not matching, thanks for you point that, we are using lane #2 (G43, G42, D43, D42).
I modified odmdata to 0x4090000, and I see ‘enable-xusb-on-uphy-lane2’, no change in device tree, but still not able to detect usb pendrive or mouse.
shouldn’t it work at least as a usb2.0 host port?
thanks
also tried change device tree to use usb3-2 with odmdata 0x4090000
Hi,
usb2-1 is A38 A39. Are the pins correct on your board?
Yes, usb2-1 uses a38/a39
Hi,
It does not looks to be an software issue now. You may check VBUS pin( voltage, turn off and on ) and TX/RX D+/D- signals.
Hi,
I tried different vbus, battery_reg which proved working on usb2-2, vdd_usb0_5v which used by usb2-0, also vdd_usb1_5v.
I will ask hardware guy to check, thanks.
How can I solve this problem? The random event reports an error and the “Please complete system configuration setup on / dev / ttyGS0 to proceed …” problem?
Hi,
Replied you in your thread. Please check:
