[SOLVED] xu4 low ethernet speed

Postby rezad » Tue Jul 04, 2017 11:55 am

I am testing the ethernet port speed and see that odroid speed is lower than 1Gb/s I have test the switch and lan cable and they are fine.
posted the issue on odroid and they said to see the output of lsusb -t .
I did and it seems that bus numbers are wrong.
they said it most likely is the archlinuxarm issue.

can someone guide me to fix this?

Code: Select all
lsusb -t
/:  Bus 06.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M
/:  Bus 05.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 480M
[b]    |__ Port 1: Dev 3, If 0, Class=Vendor Specific Class, Driver=r8152, 480M[/b]
/:  Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M
    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/2p, 5000M
/:  Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 480M
    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/2p, 480M
        |__ Port 1: Dev 3, If 0, Class=Mass Storage, Driver=usb-storage, 480M
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=exynos-ohci/3p, 12M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=exynos-ehci/3p, 480M

Can you confirm for us, the versions of these packages, which can be done with `pacman -Qs odroid-xu3`

- linux-odroid-xu3
- uboot-odroid-xu3

That's an interesting problem, if it is only the kernel, it is possible that there is actually an issue with the mainline kernel on the device, where it is muxing something incorrectly for the ethernet to come up on the wrong (port 5 vs 6) USB hub.

I don't know
I had installed linux-armv7 but it seems that I needed to install linux-odroid-xu4 and fix the issue.
