This guide is for using Arch Linux with your Beagle Bone Black.
Before you connect your BBB to your computer run: `ifconfig -a` and note which interfaces you have, mine has: eth0, lo, and wlan0.
This assumes you are ONLY connecting to your BBB via a USB cable.
After you’ve plugged it in you can do an `lsblk` to determine the device, mine was `/dev/sdc`.
You can mount and browse this easily enough with:
% sudo mkdir -p /mnt/bbb % sudo mount /dev/sdc /mnt/bbb % cd /mnt/bbb; ls
Next you want to issue: `ipconfig -a`, my system shows: eth0, eth1, lo, wlan0, after having connected the BBB, therefore the network device that will connect to the BBB is eth1.
I used `netctl`. I copied and edited the `
% cd /etc/netctl % sudo cp /examples/ethernet-dhcp bbb % cat bbb Description=’A basic dhcp ethernet connection’ Interface=eth1 Connection=ethernet IP=dhcp
I enabled and started the network with:
% sudo netctl enable bbb % sudo netctl start bbb
I also enable the dhcp client with:
% sudo systemctl enable dhcpcd.service
Now `ifconfig -a` reveals the IP address, which is 192.168.7.1. Keep in mind that this is the computer side of the network’s IP, the BBB should have the IP address: 192.168.7.2. So you can now browse via a browser, or ssh in. There is no password for the `root` user.
% ssh [email protected]
Now get your Angstrom version:
Cloud9 GNOME Image 2013.06.20
Someone recommended doing this as a first step with my BBB. So I bought a 16GB uSD flash card. Apparently anything 4GB and up is okay.
Went here: http://beagleboard.org/latest-images
Got the image that is for the BBB. On my Arch Linux i had to install 7zip
% sudo pacman -S p7zip
Extract the file with:
% 7za e demo_beaglebone_BBB-eMMC-flasher-2013.06.20.img.xz
Copy it over to the uSD card with:
% time sudo dd if=demo_beaglebone_BBB-eMMC-flasher-2013.06.20.img of=/dev/sdb bs=1M
It took a long time, maybe more than 10 minutes for the previous step.
- Then in the powered down BBB I put the micro SD (uSD) card in.
- I used a 5V/2A wall-wart power supply (do NOT power through even a
powered USB), and while holding the boot button, plugged the device in. The boot button is the one near the uSD card side.
- Hold the button down until the 4 LEDs all light simultaneously. This
took about 6 seconds.
- Then release the BBB boot button, and came back maybe 65 minutes
later. All four LEDs will be constantly on when the process is finished.
- Yank the power cord. Remove the SD card. Reinsert the power and off
you go!

If re-installing make sure to delete the files under /boot/* and /root/* since a ‘tar xf’ will not overwrite files with the same name that already exist.
/etc/resolv.conf file gets a nameserver of 8.8.8.8
Actually the boot files get modified on the SD card and we must copy those over to the eMMC boot dir.

hdparm hdparm -tT dev

useradd -m -g users -s /usr/bin/zsh fenton
echo "fenton:welcome1" | chpasswd
printf "\nfenton ALL=(ALL) NOPASSWD: ALL\n" >> /etc/sudoers
ssh-keygenscp bbf:~/.ssh/id_rsa.pub ~/projects/gitolite-admin/keydiron your install SD card, create two partitions, the first for /usr and second for /home. Maybe 4 GB and 12 GB respectively.
boot up with card in and do:
Add a line like the following to /etc/fstab
/dev/mmcblk0p1 /usr ext4 defaults 0 2
reboot
CANNOT delete old ‘/usr’ as I believe it is used in the bootup process before the ‘/etc/fstab’ is read. So just leave it there… then lets delete the old /usr to free up space:
It’s a realtek
maybe dont take the armv7 headers, maybe use default of am33
Install this driver:
% sudo pacman -S xf86-video-fbdev
