beaglebone: USB-to-Ethernet interface not working

[spagoc]

Ubuntu on Beaglebone: how to have USB-to-Ethernet interface working?

I am using Beaglebone booted with Ubuntu following the direction from:

http://elinux.org/BeagleBoardUbuntu#Demo_Image

I also use Ubuntu on my host PC connected to the Beaglebone by a USB
cable only (no LAN cable).
In this configuration USB-to-serial works and I have the very useful
Beaglebone console.
If I boot with Angstrom USB-to-Ethernet works. That is done via an
eth2 interface that appears on my PC and I give it the address
192.168.7.1 (the Beaglebone answer from 192.168.7.2). The USB-to-
Ethernet functionality starts disconnecting the Beaglebone-Angstom USB
mass storage (as I red from the related Beaglebone README.htm). But
when the Beaglebone boots with Ubuntu I have no USB mass storage to
disconnect and no eth2, or similar, interface appears.
So please give me some advice in order to solve my problem.

Thanks

Rino

Hi Rino,

In testing in the lab, most of the usb problems seem to be fixed now..

Care to give this kernel a try?

On the beaglebone:
wget http://rcn-ee.net/deb/oneiric-armel/v3.2.0-psp0/install-me.sh
/bin/bash install-me.sh

Regards,

Hi Rino,

[ 8.097619] CPSW phy found : id is : 0x7c0f1
[ 8.104503] PHY 0:01 not found

After seeing ^^, how long did you wait (longer then 2mins is a problem)? As long as the D2 led (next to the usb/eth connectors) the board is still running. With ubuntu oneiric, it's setup by default to wait at least 2mins when an "eth0" setting exists in /etc/network/interfaces.. which i've done with the demo image. I've also patched out about 1 min 40 seconds of the 2 minute wait.. So with no Ethernet plugged into the jack, it should only look frozen for about 20 seconds or so... I haven't found a way to print "attempting network connection" so that it doesn't look frozen..

Is d2 still blinking?

try commenting out:

auto eth0
iface eth0 inet dhcp

in: /etc/network/interfaces

Try, another todays updated kernel. (couple beaglebone i2c tweaks..)
http://rcn-ee.homeip.net:81/testing/beaglebone/

sudp cp X.uImage /media/boot/uImage
sudo tar xfv X-modules.tar.gz -C /media/rootfs

Hi Robert,

you are right, maybe the boot slowness was when I tried beaglebone with an
ethernet cable but in a network environment without DHCP.

Then following your instructions I tried all the following kernel in my
ordinary setup: USB cable only (no Ethernet cable):

Linux omap 3.1.0-psp3 #1 SMP Fri Dec 23 10:44:55 UTC 2011 armv7l armv7l
armv7l GNU/Linux
Linux omap 3.2.0-psp0 #1 Wed Feb 1 00:21:54 UTC 2012 armv7l armv7l armv7l
GNU/Linux
Linux omap 3.2.0-psp0.1 #1 Wed Feb 1 11:39:04 CST 2012 armv7l armv7l armv7l
GNU/Linux

They boot in about 40 sec without ethernet cable.
Of course the most stable kernel appears to me to be the first one, then
the third one.

With the second and third ones the led blinks during use.

Sometimes I found myself in a 'U-Boot#' prompt environment. What is it? And

when is it supposed to appear?

U-Boot# version
U-Boot 2011.09-dirty (Nov 21 2011 - 10:44:32)
arm-angstrom-linux-gnueabi-gcc (GCC) 4.5.4 20110917 (prerelease)
GNU ld (GNU Binutils) 2.20.1.20100303

U-Boot#

Also with the third kernel no eth2 interface appears

try commenting out:
auto eth0
iface eth0 inet dhcp

I did that and I did:
$ sudo /etc/init.d/networking restart
I got a deprecated msg (how to avoid it?)
ifconfig gives always only the same eth0 info.
I am stuck.

so I wonder:
a)how to start the USB-to-Ethernet functionality?
b)what is the default USB-to-Ethernet network interface?
c)what is its default IP address?

Regards

Rino

Hi Robert,
I think you are going in the right direction in order to solve the problem.
That's what I discovered using the last ubuntu distro with the kernel:

Linux omap 3.2.0-psp1 #1 Fri Feb 3 15:15:23 UTC 2012 armv7l armv7l armv7l GNU/Linux

An usb0 network interface appears both on beaglebord and on the host Ubuntu PC
I gave IP address to both of them:

PC: sudo ifconfig usb0 192.168.7.1
Beaglebone: sudo ifconfig usb0 192.168.7.2

but ping dosn't work

Maybe can be a usbnet module problem because:
on host PC:
root@MCP7A:~# lsmod |grep usbnet
usbnet 25214 1 cdc_ether

but on Beaglebone:
root@omap:# lsmod |grep usbnet
root@omap:#

really no module appears to be loaded in the kernel because lsmod give an empty set:
root@omap:# lsmod
Module Size Used by
root@omap:#

I tried modprobe but without success.

With Angstrom and USB-to-Ethernet in working state:
$ lsmod |grep usbnet
usbnet 25214 2 cdc_subset,cdc_ether

I hope this information can be useful for you.
Regards
