could not insert 'g_ether': No such device

[Igor Jędrzejczak]

Hi,

I'm trying to make Ubuntu 16.04.2 with TI v4.4.x: Real-Time kernel work. I'm stuck with a problem to configure ethernet over USB. I'm doing everything as explained here: https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-usbgadget but when I run the beaglebone-black-g-ether-load.sh script, I get modprobe: ERROR: could not insert 'g_ether': No such device...

Here is my dmesg: https://pastebin.com/KWBgdTTm

Here is my lsmod: https://pastebin.com/vr7J6QHA

I've been facing similar problem before, when I've been setting up 4.4 non-rt kernel, and up then solution to my problem was this script added to rc.local: https://pastebin.com/s7K8Kjrf

This time it doesn't help though...

I'll appreciate any help.

Regards

Igor

Why isn't this connection working then? Network manager in my host Ubuntu shows it's still connecting. On the list of connections I already have my BBB, I can ping it, but when i try to ssh to it, I get no route to host error...

Here is an image of my networks list: http://imgur.com/a/GUQck

ssh deb...@192.168.7.2

If that doesn't work..

sudo ifconfig -a

As I manetioned above - I've got Ubuntu image, not debian.

Command ubu...@192.168.7.2 returns "No route to host"

Yeah your right for Ubuntu..

Try

sudo dhclient eth1

To see if you can get a proper ip from the beagle.

Thanks for this solution - after running dhclient eth1 that interface got a proper IP address and I was able to connect through ssh with BBB.

I don't consider this a final solution though, as this involves too much uncertainity and manual work in order to simply connect with the device (especially as this can happen automatically). Unfortunately I don't feel myself to be that strong in networking topics to be able to find a final solution myself. So thanks for that one, but could you tell me what else can I do?

@Robert - I did everything as you described here: https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-usbgadget

Why do I have two USB interfaces showing up (USB0 and USB1)? If I cannot load g_ether because u_ether is already loaded, do I need to run beaglebone-black-g-ether-load.sh during every boot?

Regards

The two interfaces are normal for all images linked from my elinux.org pages:

http://elinux.org/BeagleBoardUbuntu

On the eewiki.net page i haven't migrated things to the dual usb option yet.. *

This usb option, allows both Microsoft (7, 8.x, 10) to automatly
install a built-in usb-networking driver without our signed driver..
the "other" inteface also works with a built-in MacOSX driver..

It's just linux that see's both interfaces...

[Igor Jędrzejczak]

Thanks for the info.

Now, even when I run dhclient eth1 I cannot get IP assigned... Like I said, it's lottery...

So it doesn't work and I don't know why... Great...
