Asterisk for Raspberry Pi on ArchLinux

Note: Work In Progress

These instructions work for the Raberry Pi B-512 version with 512 MB RAM and not the 256MB version. You can follow these instruction for the 256MB version but you will have to skip the perl modules which is used for fax2mail and Google's text to speech.

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

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

Write image to sdcard and boot Rasberry Pi.

expand sdcard to use full capacity
  #  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

  # resize2fs /dev/mmcblk0p2
  # reboot

create swap file
  # fallocate -l 256M /swapfile
  # chmod 600 /swapfile
  # mkswap /swapfile
  # swapon /swapfile

  # vi /etc/fstab
       /swapfile none swap defaults 0 0  (add)
