Re: [beagleboard] Re: Beaglebone and Chromebook connection

[john]

I'm seeing the same behavior on a newer 4.14 kernel beaglebone image. If 
the Beaglebone is already booted up and connected to a Chromebook, then the 
USB device will properly be assigned the 192.168.7.1 address. If the 
Beaglebone is powered over USB, though, the Chromebook seems to not see a 
network device when it's immediately plugged in, as it hasn't had time to 
boot, and never checks again. I can switch the Beaglebone board over to a 
5V power supply, unplug the USB, replug it in and the Chromebook is able to 
connect without issue. This seems like a Chromebook issue to me, but does 
anyone have any suggestions for how to fix this?

Re: [beagleboard] Re: Beaglebone and Chromebook connection

[Paul Wolfson]

The trick is creating a network route to the USB gadget.  If you are
familiar with a unix style command line, the tools are there to mount the
192.168.7.x network in the Chrome OS terminal.  I am travelling and don't
have access to my BBB, but I'll try later when I have physical access,
rather than over a VPN.  Chrome OS should automatically mount the USB
device (BBB) as a network device, just as it would a USB-LAN adapter or
USB-wireless device.  Chrome OS has to see a dhcp server on the 192.168.7.x
network of the connection will fail unless you explicitly mount the BBB on
a static Chrome OS address.  At that point, you might as well just use the
built in BBB ethernet adapter.

You will have exactly the same problem in Windows 7, 8.1 and 10; there has
to be a route to the 192.168.7.x subnet.  Either you need a router on that
subnet or you need to specify a route explicitly.

Kind regards,
Paul

[beagleboard] Re: Beaglebone and Chromebook connection

[christiant1971]

I can confirm that when I connect the beaglebone to the chromebook and 
power up the chromebook, the network never comes up, but if I get an update 
on the chromebook and can 'soft' reboot it without shutting down the 
beaglebone, when the chromebook comes back up, the network is up. If there 
was a way I could reboot the chromebook once the beaglebone booted up, that 
would fix my problem, but from what I can see, there is no way to do a 
reboot of a chromebook, except for when you get a system update.

Re: [beagleboard] Re: Beaglebone and Chromebook connection

[christiant1971]

Hi Paul,
Thanks for posting this info.
There might be an issue with my Chromebook then because they network 
doesn't seem to come up. Just out of curiosity, which OS image are you 
using for your Beaglebone?
Also yesterday after I finished running apt-get upgrade, all of the sudden 
they USB network started working. Of course after I rebooted the Beaglebone 
never came back up again.
When I get more time, I will play with different Linux images on the 
Beaglebone see if that changes anything.
Cheers
Christian

Hi Wally,
Thanks for your reply.
I'm using the latest Debian image from the downloads sections. Also I ran 
apt-get dist-upgrade to make sure it had the latest version of all the 
packages.
I need to investigate the 'USB gadget interface'. All I know is that from

I imagine that when you say 'wired' connection you mean using a regular 
ethernet cable rather than USB. Ethernet works just fine, but it kindof 
makes it clunkier than having a Chromebook ->USB->Beaglebone.

Hi Greg,
Thanks for your feedback.
I have ssh on my Chromebook, but this doesn't work as I can't even ping the 
beaglebone. The network needs to be up before I can run ssh or http, etc. 
Just trying to figure out how to get the network connection established.

What Beaglebone image are you running?   I've found many of the recent 
images have issues with getting the "USB gadget" Ethernet over USB to work 
reliably.   Without the USB gadget interface the ssh debian@192.168.7.2 
will not work.  Can you try a wired Ethernet connection?  Then the ssh 
login should work to the IP your router assigns to the Beaglebone.

Here is one method.  Get the "Secure Shell" extension.  This will give you 
a Linux style terminal in a tab.  See if you can:

ssh root@192.168.7.2

If your IP address is different, adjust in the above command.

I've tried this and it works.  I didn't do anything beyond testing to see 
if it works.  I normally use a Linux desktop to work with my Beaglebones.
