[Buildroot] USB on rock64

[no-one-you-know]

Hopefully it's OK to send generic questions here.
I've built an image (glibc/systemv/eudev) for my Rock64 and according to the announcement on this mailing list USB should be working.

And according to dmesg and lsusb, it is (as far as I can tell):

# dmesg|grep -i usb

Bus 002 Device 001: ID 1d6b:0002
Bus 001 Device 001: ID 1d6b:0002

But when I plug a USB flash drive in, nothing is detected.  Both lsusb and re-running dmesg show no change - like nothing is there

Is this something I've left out of the 'target packages' selection?  How can I troubleshoot this further?

Thanks

 It's OK, but don't expect answers :-)

 It would have been a good idea to include the original contributer of the
rock64_defconfig in Cc - I've done that now.

 Have you tried with other devices? USB3 flash drives don't always work well in
USB2 ports (yes, they should, but they don't...). A mouse is often a much better
device for testing.

Hello - thanks for responding.

Yes, I tried with a USB2 flash drive and a USB keyboard.  Nothing detected.
I'm reasonably confident it's the kernel rather than a missing package because I used the same uboot/kernel with a different rootfs and have the same behaviour.

I've just compiled rock64_defconfig from master and USB does ineed
work, I checked USB3 and USB2 pendrives and keyboard but...

Only 1 USB port seems to work - bottom USB2.0. I remember there
were some issues with USB3 at the time I did the port, but cannot
remember why the upper USB2 does not work, maybe some regulator is
not enabled in default dtb?

Try different USB port and see if that works.

Weird, I get nothing on any port with a USB2 flash drive and a USB keyboard.

I was using the 2018.08 version with quite a few different options set.  I'm assuming that when you compiled it you left everything default so I'll give that a go with the latest rc version and see what happens.

Thanks for helping.

Default buildroot config for rock64 uses mainline kernel with
default arch's generic defconfig which is not tailored for rock64.
It might be possible that you have some newer revision than mine,
which is not fully supported in mainline kernel. Couple of things
to consider:

1) you might want to change kernel version to newest one, maybe
your board is better supported in newer kernel.

2) you can try and use kernel from ayufan that is made for rock64
(forked from official rockchip kernel repo) which surely will have
drivers mainline won't. He used to very actively support rock64 in
the past, I don't know how about now - last commit is 3 months old

I think you must be right.  I just downloaded 2019.11rc and built a vanilla image with just "make rock64_defconfig && make" and I can't get anything out of the USB ports.

Thanks for the info and advice.  It's appreciated.

Just one more thing on this...
I rebuilt my image using 2019.11.rc2 and kernel 5.3 (from the menuconfig options) and my USB2 ports are working now :)

Thanks again for the advice.
