Arch linux on raspberry pi April 27

Quick memo for a setup process for arch linux arm on rpi with a wireless adapter:

  1. Plugin the ethenet cable into rpi. Verify the wireless adapter is recognized by the kernel using lsusb:

     [root@alarmpi ~]# lsusb
 Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp. LAN9500 Ethernet 10/100 Adapter
 Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
 Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
 Bus 001 Device 004: ID 050d:945a Belkin Components F7D1101 v1 Basic Wireless Adapter [Realtek RTL8188SU]

  2. Update the system: pacman -Syu

  3. Install the base system and vim, netctl is the replcaement for the netcfg package: packman -S base-devel vim netctl
  4. Following is just a replica of contents in arch wiki: cp /etc/netctl/examples/wireless-wpa /etc/netctl

  5. Editing the netctl/wireless-wpa file: vim /etc/netctl/wireless-wpa

     ESSID='yourssid'
 Key='yourpassword'

  6. Testing the connection: netctl start wireless-wpa

  7. See the logs: netctl status wireless-wpa

     [root@alarmpi netctl]# netctl status wireless-wpa
