View source for Asterisk for Raspberry Pi on ArchLinux

If you don't want to follow these instructions and would prefer to download an image you can do so by downloading the image from [[Asterisk for Raspberry Pi Image]].

The following instructions are based on Arch Linux ARM (archlinux-hf-2012-09-18.zip)

= Write Image to SD Card =
Using [http://launchpad.net/win32-image-writer/+download Win32DiskImager] and the latest version of [http://www.raspberrypi.org/downloads Arch Linux ARM] from Raspberry Pi write the image to the SD card.

Once the image is written insert the SD card into the Raspberry Pi and boot.  The device will get an IP address from DHCP.

= Expand Partition =
Now that the device has booted log on and change the default partition from 2 GB to the maximum partition of your SD card.
<pre>
fdisk /dev/mmcblk0
d (delete)
2 (partition 2)
n (new)
p (primary partition)
2 (partition 2 as previously deleted)
enter (accept default start sector)
enter (accept default end sector)
w (write changes)

reboot
</pre>

Once the rPi has rebooted
<pre>
resize2fs /dev/mmcblk0p2
reboot
</pre>


= Swap File =
As the rPi has limited RAM, either 256 or 512 depending on your version we'll create a swap file to allow application to use higher memory if required.

I would recommend allocating the size of the swap file to be that equal to the RAM size.
<pre>
fallocate -l 256M /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile
</pre>

The swap file is now active.  We now need to ensure that it is used at boot.
<pre>
vi /etc/fstab
</pre>
add the line to the file
<pre>
/swapfile none swap defaults 0 0
</pre>

= RAM Sizes =

The RAM can be slipt between the CPU and GPU as follows:
<pre>
for 256MB version, 240/16, 224/32,  192/64, 128/128
for 512MB version, 496/16, 384/128, 256/256
</pre>

The default for the 256MB version is 224/32.  As we don't need any GPU power we'll change this to 240/16.
<pre>
vi /boot/config.txt
</pre>
add a line at the bottom
<pre>
gpu_mem=16
</pre>

<pre>
pacman -Syu
reboot
</pre>
