headlesspi

This is a simple bash script that installs Arch Linux ARM onto an SD card and sets it up to automatically connect to a user-specified Wi-Fi profile once the Raspberry Pi is powered on. This allows the Pi Model A, which lacks an Ethernet port, to be set up and configured with just a USB Wi-Fi dongle (no screen, keyboard or mouse needed).

The basic Arch Linux ARM installation steps are outlined here: https://archlinuxarm.org/platforms/armv6/raspberry-pi

Warning! The script will overwrite your SD card. Root priviliges are required.

Usage

1. Insert your SD card into your computer. Use dmesg to verify that it was detected as /dev/mmcblk0. This is the device that the script will target.

2. Run the script with sudo ./rpisetup --install. The downloading and unpacking of the archive can take a while.

3. Open a terminal and check all the IPs on your LAN with nmap -sn <RouterIP>/24, e.g. 192.168.0.1/24. Your router might have a different IP. You can find out what it is with ip route show default | awk '{ print $3 }'.

4. Power on the Pi with the prepared SD card. Give it a little time to boot.

5. Run nmap again and it there should be a new IP listed. This is the IP address of the Raspberry Pi.

6. Connect to the Pi with ssh alarm@<IP> and log in using the default password alarm.
