Note: Support for the ARM architecture is provided on http://archlinuxarm.org/

How mature is Raspberry Pi (RPI). A brief overview.

What is Raspberry Pi

It is a minimalist computer built for ARMv6 architecture. More information about this project and technical specification.

Installing Arch Linux ARM

In this manual will describe only essential moments for different RPI. Other procedures are the same instructions for ArchLinux. The only exception is the basic initialization and installation of equipment. It is further assumed that the configuration is performed on a machine running Archlinux.

Backup Cards

If you own an official card provided with your RPI (for example) recommend before installing Arch ARM Linux to backup using dd. The path must be specified to the device /dev/sdX not for another partition /dev/sdc1

# dd if=/dev/sdX of=$HOME/backup_RPi.img
Note: There is a bit copy of the card. The resulting file is the same size as your card.
Note: card may not be installed.
Warning: Bad parameters can damage your data.


Installation is similar to backing card. Download the image file from Arch Linux ARM

# dd bs=1M if=/path/to/archlinux.img of=/dev/sdX

After inserting the card into the slot on the PPi should boot the base system Arch Linux ARM.


The downloaded image file is approximately 2 gigabytes of which is /boot 94 megabytes and / 1.8 gigabytes. If you used a larger card to 2GB, so I recommend the rest of the card to connect as /home (or /usr). Clearance must be formatted using the example Gparted. At the first possible opportunity (after booting RPI or after mounting the card in the computer) need to be adjusted /etc/fstab

# sudo vim /etc/fstab

For example, add

/dev/mmcblk0p3 / home ext4 defaults 0 0

The first operation

Summary of the official procedure:

Remote SSH access

If you do not use the HDMI output RPI and you will access the device using SSH, the following applies. Root pasword is: root. I recommend to perform key exchange SSH_Keys.

$ ssh root@ (Use your Ip RPI)


# vim /etc/locale.gen

uncomment en_US.UTF-8 UTF-8 and en_US ISO-8859-2

generate localization files

# locale-gen

Setting the time and date using OpenNTP


Setting the time and date manually


Changing the root password

After the first start RPI is native root password to root. It is therefore necessary to change it. Executed after power command passwd

# passwd root

Adding another user

Using adduser to add the user.

# adduser


Start visudo

# sudo visudo

add the line "USER ALL = (ALL) ALL" below the line root ALL = (ALL) ALL


The generic xf86-video-fbdev driver can be used.
