==Installing Arch Linux ARM==

== 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.
+
See the [http://archlinuxarm.org/platforms/armv6/raspberry-pi#qt-platform_tabs-ui-tabs2 archlinuxarm documentation].
  
==Backup Cards==  
+
== Video ==
If you own an official card provided with your RPI, for example http://cz.farnell.com/samsung/raspberry-pi-prog-4gb-sdcard/memory-sdcard-raspberry-pi-4gb/dp/2113756 recommend before installing Arch ARM Linux to backup using {{ic | dd}}. The path must be specified to the device {{ic | / dev / sdX}} not for another partition / dev/sdc1
+
  
# Dd if = / path / to / sdX of = / home / $ USER / backup_RPi.img
+
The generic {{pkg|xf86-video-fbdev}} driver can be used.
  
 +
== Serial Console ==
 +
Edit the default /boot/cmdline.txt
  
{{Note | There is a bit copy of the card. The resulting file is the same size as your card.}}
+
Change loglevel to 5 to see boot messages
{{Note | card may not be installed.}}
+
# loglevel=5
{{Warning | Bad parameters can damage your data.}}
+
  
==Installation==
+
Change speed from 115200 to 38400
 +
# console=ttyAMA0,38400 kgdboc=ttyAMA0,38400
  
Installation is similar to backing card. Download the image file from Arch Linux ARM http://archlinuxarm.org/platforms/armv6/raspberry-pi
+
Start getty service
Image copy using {{ic | dd}}.
+
# systemctl start getty@ttyAMA0
  
  # Dd bs = 1M if = / path / to / archlinux.img of = / dev / sdX
+
Enable on boot
 +
  # systemctl enable getty@ttyAMA0.service
  
After inserting the card into the slot on the PPi should boot the base system Arch Linux ARM.
+
Creating the proper service link:
 +
# ln -s /usr/lib/systemd/system/getty@.service /etc/systemd/system/getty.target.wants/getty@ttyAMA0.service
  
==Home==
+
Then connect :)
 +
# screen /dev/ttyUSB0 38400
  
The downloaded image file is approximately 2 gigabytes of which is / boot and 94 megabytes / 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 {{ic | / etc / fstab}}
+
Referenced from these [http://www.raspberrypi.org/phpBB3/viewtopic.php?f=53&t=19186] posts [https://bbs.archlinux.org/viewtopic.php?id=144847]
 
+
# Sudo vim / etc / fstab
+
 
+
For example, add
+
 
+
/ Dev/mmcblk0p3 / home ext4 defaults 0 0
+
 
+
The first operation == ==
+
 
+
The official procedure here: http://archlinuxarm.org/support/guides/system/first-steps
+
Summary:
+
 
+
==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: {{ic | root}}. Dopročuji perform key exchange [[SSH_Keys]].
+
 
+
~ Ssh root@192.168.1.123 (Use your Ip RPI)
+
 
+
==Localization==
+
 
+
# Vim / etc / locale.gen
+
 
+
uncomment {{ic | en_US.UTF-8 UTF-8}} and {{ic | en_US ISO-8859-2}}
+
 
+
generate localization files
+
 
+
# Locale-gen
+
 
+
==Setting the time and date using OpenNTP==
+
 
+
dopnit
+
 
+
==Setting the time and date manually==
+
 
+
complete
+
 
+
==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 {{ic | passwd}}
+
 
+
# Passwd root
+
 
+
==Adding another user==
+
Ic using {{|}} adduser to add the user.
+
 
+
# Adduser
+
 
+
==Sudo==
+
Start ic visudo
+
 
+
# Sudo visudo
+
 
+
add the line "USER ALL = (ALL) ALL" below the line root ALL = (ALL) ALL
+
 
+
==Installing programs and environment==
+
 
+
Below is a brief overview of the basic packages and procedures that are initially desolation RPI could come in handy.
+
 
+
==Search==
+
 
+
To search for files and folders on the disc serves [[mlocate]].
+
 
+
# Pacman-S mlocate
+
 
+
after installation, you must restore the database
+
 
+
# Updatedb
+
 
+
==Shell==
+
For work I recommend [[zsh]].
+
 
+
# Pacman-S zsh
+
 
+
run
+
 
+
$ Chsh
+
 
+
and set
+
+
/ Bin / zsh
+
 
+
==Graphical environment==
+
 
+
You need to install X server [[xorg]]:
+
 
+
# Pacman-S xorg-server xorg-xinit xorg-server-utils xinit xterm xorg-
+
 
+
[[Mesa]]
+
 
+
# Pacman-S mesa
+
 
+
Video card drivers [[xf-video]]
+
 
+
# Pacman-SYF xf86-video-fbdev
+
 
+
 
+
Which is connected with [[gamin]] and [[dbus]]
+
 
+
# Pacman-S dbus gamin
+
 
+
Graphical environment [[LXDE]]:
+
 
+
# Pacman lxde
+
 
+
further into the set {{ic | ~ /. xinitrc}} add the following line:
+
 
+
$ Vim ~ /. Xinitrc (if they do not root)
+
 
+
insert
+
 
+
exec ck-launch-session dbus-launch startlxde
+
 
+
==Running LXDE environment:==
+
 
+
startx

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

See the archlinuxarm documentation.

Video

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

Serial Console

Edit the default /boot/cmdline.txt

Change loglevel to 5 to see boot messages

# loglevel=5

Change speed from 115200 to 38400

# console=ttyAMA0,38400 kgdboc=ttyAMA0,38400

Start getty service

# systemctl start getty@ttyAMA0

Enable on boot

# systemctl enable getty@ttyAMA0.service

Creating the proper service link:

# ln -s /usr/lib/systemd/system/getty@.service /etc/systemd/system/getty.target.wants/getty@ttyAMA0.service

Then connect :)

# screen /dev/ttyUSB0 38400
