This document provides instructions for installing Firefox OS on a Raspberry Pi. It outlines downloading and installing Raspbian ("wheezy") onto an SD card. Then it describes downloading Firefox OS files, unpacking them, and running Firefox OS on the Raspberry Pi using the profile data. Finally, it discusses future additions like touch displays, cameras, and 3G modules to turn it into a basic phone.

24. Advance Course

25. Raspbian “wheezy”
Install
Tools
Personal Computer(OS X)
SD Card ,SD Card R/W

26. Prepare of Environment
ex: OSX
Mac Ports | Homebrew
sudo port install wget
brew install wget

27. Install Start!
Make Directory
$ cd
$ mkdir raspi
$ cd raspi
[dir]: Directory name
cd [dir]: Change Directory for [dir]
(if [dir] = empty then [dir] = HomeDirectory)
mkdir [dir]: Make Directory

28. Download
Raspbian “wheezy”
$ wget http://downloads.raspberrypi.org/
images/raspbian/2012-10-28-wheezy-
raspbian/2012-10-28-wheezy-raspbian.zip
You can get hire ↓
http://www.raspberrypi.org/
downloads

29. Unpack Zip
$ unzip 2012-10-28-wheezy-raspbian.zip
[file]: Zip File name
unzip [file]: Unpack [file]

30. Insert SD card
$ df
df: Show disk parameters
Filesystem 512-blocks Used Available Capacity Mounted on
/dev/disk0s2 723603632 442647392 280444240 62% /
devfs 376 376 0 100% /dev
map -hosts 0 0 0 100% /net
map auto_home 0 0 0 100% /home
/dev/disk2s1 31488000 4480 31483520 1% /Volumes/NO NAME
Take note : /dev/disk2s1(BSD Name)

31. Unmount SD Card
$ sudo diskutil unmount /dev/disk2s1
password: *****
[com]: Command
[disk]: BSD name
sudo [com]: Run command as super user
password: *****: Super user password
diskutil: OSX disk utility command
diskutil unmount [disk]: Unmount disk

32. Write
Debian “wheezy”
$ sudo dd bs=1m
if=./2012-10-28-wheezy-raspbian.img
of=/dev/rdisk2
[img disk]: Image disk
./ : Current Directory
/ : Root Directory
dd: Disk dump
(Copy all image)
bs=*: Block Size(1m=1MB)
if=[img disk]: Source image disk
of=[disk]: Output disk

33. Write
Debian “wheezy”
$ sudo dd bs=1m
if=./2012-10-28-wheezy-raspbian.img
of=/dev/rdisk2
Q: !? I noted /dev/disk2s1.
A: /dev/disk2s1 is one of disk partition
Add r for raw access to disk2
s1 means partition
Therefore “/dev/rdisk2”

34. Eject SD Card
$ sudo diskutil eject /dev/rdisk2
diskutil eject [disk]: eject [disk]

35. First Step of Pi
expand_rootfs
Use SD Card full access
configure_keyboard
Select your keyboard layout
change_timezone
ex:「Asia」→「Tokyo」
update
Update Debian

36. ☕
Coffee Break
