BBB, how to connect to pc?

General Discussion
1

Hello,

I have problem with BBB,

TLDR:
I can’t make the connection to pc via USB work. I use Ubuntu 18 KDE Plasma
I see the beagleboard as device, I can browse inside but I cant access it like Ethernet connection.
I tried to access 192.168.6.2 with browse or $ ssh 192.168.7.2 -l root , but nothing.

Is there something that I miss? How can I use the USB cable to connect to it?

Full Info:
I download the latest image “AM3358 Debian 10.3 2020-04-06 4GB SD IoT”
Flash the sd card with balena etcher. Put the SD card on the beagleboard and it works.
I used ftdi seral convertor to read serial from PCB, together with picocom.
debian@beaglebone:~$ uname -a
Linux beaglebone 4.19.94-ti-r42 #1buster SMP PREEMPT Tue Mar 31 19:38:29 UTC 2020 armv7l GNU/Linux

But I cant access the serial straight from the USB. I have Ubuntu 18 kde plasma.
I followed this guide - https://cdn-learn.adafruit.com/downloads/pdf/ssh-to-beaglebone-black-over-usb.pdf
"Installing Drivers (Linux)
For the BBB to be able to do ad hoc networking with your computer, there is nothing
to install on the BBB itself. Its all set up and ready to go. However, to be able to run
this on a Linux computer, you will need to install the udev rules found here: http://
beagleboard.org/static/Drivers/Linux/FTDI/mkudevrule.sh (https://adafru.it/cc2)
This script will create a new file called 73-beaglebone.rules in /etc/udev/rules.d/You
will probably need to run the script as superuser.

Browsing Your BeagleBone
Before we connect using SSH, lets just test that the connection is active by trying to
connect to the BBB with a browser.
The BBB will have an IP address, so using Chrome or Firefox (not Internet Explorer)
connect to the URL http://192.168.7.2 (https://adafru.it/cc3)
You should see a helpful introductory web page served by the BeagleBoard itself."

After I installed the drivers I see the beaglebone as device I can browse inside the but I cant access 192.168.6.2 (or 7.2) or $ ssh 192.168.7.2 -l root.

Hi @NICHIRENSHU with that old image, two new usb ethernet devices should pop up on Ubuntu 18 without installing any other drivers…

What does “ifconfig -a” show?

sudo ifconfig -a

I see that the two enx3403de8d01 show up when the board is connected

5 
sudo dhclient enx3403de8d01a3

Or use the network gui in Ubuntu 18…

Can I ask you a question?

Is there anyway to update the firmware without removing th SD card and plugin it to a pc?
To update it through this connection?

Thank you!

It worked it opened cloud9 beaglebone page.
This looks like visual studio code in website.

And “putty” works too!
I connect to 192.168.7.2

No, for a full image ‘reflash’ remove the microSD…
