Installing Debian 8.6 on a BeagleBone Black

I’ve finally had practical reason to get the BeagleBone Black out of the drawer and start using it as an home server (more later). It’s a nice, quiet little machine with 512 megs of RAM and a 1ghz ARM CPU. I followed the instructions from https://beagleboard.org/getting-started to connect to it via the serial port over USB, which allowed me to connect to the web server on the included OS. Turns out I didn’t really need to do this, all I needed to do was flash my microSD card and install Debian on it.

For more in-depth Linux notes, I referred to http://elinux.org/Beagleboard:BeagleBoneBlack

I downloaded the latest Debian stable “Jessie” build for ARMHF from here. That image turned out to be a bit bloated with X and desktop tools, so I switched to the “IOT” image. I flashed the image onto a 32 gig microSD card with Etcher for OSX, which was quite painless.

Debian on the BeagleBone Black

Next I popped the microSD card into the BeagleBone and rebooted into Debian. I was able to connect to the serial console over USB with instructions from here. For my instance, the command was

screen /dev/tty.usbmodem1413

I changed the debian user password away from the default and plugged in a network cable.
Once it was on the network I could SSH to it, I probably didn’t need to use the serial console at all if I’d just looked for the IP address off the router.

I copied over my SSH key so I wouldn’t need to use my password when logging in.

scp ~/.ssh/id_rsa.pub debian@192.168.0.11:~/.ssh/authorized_keys

Next I did an apt-get update; apt-get upgrade to get the latest bits and then shut it down.

I plugged directly into the router and powered via the USB port, since it’s meant to be an externally-accessible bastion box.

Final touches

I also needed to make sure we used the whole microSD, so I followed these instructions:

cd /opt/scripts/tools/
git pull
sudo ./grow_partition.sh
sudo reboot

I checked the list of timezones and set mine to Sydney.

timedatectl list-timezones
sudo timedatectl set-timezone Australia/Sydney

and finally

apt-get install emacs-nox

Now it was ready to use.
