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

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 384000
