[SOLVED] ODROID-XU USB3 not working Arch 5.8.9-1

[doggisbag]

Hi, first of all i want to really thanks to ALARM team and Krzysztof Kozlowski for maintaining Samsung Exynos Linux drivers. Keep doing a great work!

My problem is the following. From the install instructions it says that USB3 is not working. I'm currently using kernel 5.8.x and i really want to know why or how could i do to make it work. I don't have enough experience in linux world in general (including embedded), but AFAIK devices definitions are creates in the device tree file. In older ubuntu and android kernel releseases (3.4.x) the USB3 seemed to work fine, so i think configs could be modified to have it working on arch's newer kernel.

It's interesting for me also that during boot kernel logs shows that xhci driver related with usb3.0 and older usb specificacions enabled, in addition that in other line shows a message that this device support usb 3.0 host interface, but currently only USB 2.0 ports/hub are working (detected with lsusb and able to power some usb devices). I have read on Xen related package that USB3 was disabled due to overcurrent and some instabilities on it.

lsusb -t output:

Despite all being said, it's still awesome that an deprecated board like XU is working with latest kernels. Obviously thanks to the maintainers doing a great job!

Anyways, any suggestions will be helpful!

Update:

Looking at the Linux Kernel USB3 Driver definitions, i've found that USB has several modes of operation, which are then implemented on the device tree of a specific system. Looking at the Schematics of XU_Rev0.4 found at https://odroid.in/?directory=.%2Fmirror ... PCB_DWG%2F, i've checked that USB3.0 type A is defined as usb3_1(as shown in image below) in schematics.

In addition, the nodes related to that port are shown at PMIC sheet #9, where vdd33 and vdd10 usb3 are related with LDO regulators (shown in images below).

LDO12-15.png (93.76 KiB) Viewed 702 times

Following those leads, i've checked the device tree file stored at /boot/dtbs/exynos5410-odroidxu.dtb using dtc command to save a copy as .dts file. Then i've looked at the usb3 node definitions and found that usb3_1 node has been defined as "peripheral" instead of "host" mode. Changing that as shown in picture below.

Finally i've proceeded to export the modified dts and overwrite the .dtb file.

Now my lsusb output has changed:

Now it shows bus 05 and 06 with Superspeed capabilities. Sadly i've connected an USB3.0 External drive with its own power supply and it not worked. But now i'm having different logs so i think i'm doing some progress.

Anyways, if someone is interested i'll keep updating my efforts. Again thanks to the maintainer team for doing a great work!

Krzysztof's patch finally fixed the USB 3.0 issue, now my Seagate SATA3 Drive is being detected and powered through the USB 3.0 port and in addition no overcurrent condition is present on logs. To enable this you should read description from the link above.

Drive being detected correctly at lsub output Bus 04 (Port 1: Dev 2)

Code: Select all

$ lsusb -t

Basic disk speed test:

1. microSD (hdparm -Tt /dev/mmcblk1p2) (in your case you'll need to check which enumeration has your SD card):

Timing buffered disk reads: 70 MB in 3.07 seconds = 22.79 MB/sec

2. SATA3 Seagate 4TB USB3.0:

Timing buffered disk reads: 442 MB in 3.01 seconds = 146.76 MB/sec

From now on i'll try stability of the USB3 port.

Thanks again to Krzysztof's amazing work!
