以下URLからUbuntu14.04 armhfのルートファイルシステムをダウンロードできます。
なお、今回はwgetで取得しますのでwebサイトにおけるダウンロードはいりません。
http://www.armhf.com/download/
ワークスペースにファイルシステムをダウンロードします。
$ cd ~/work_dir
$ wget http://s3.armhf.com/dist/basefs/ubuntu-trusty-14.04-armhf.com-20140603.tar.xz
ダウンロードしたファイルシステム用のディレクトリを作成し、展開します。
以下のコマンドで展開に失敗する場合はGUIからも展開できます。
$ mkdir ubuntu_rootfs
$ cd ubuntu_rootfs
$ tar -Jxvf ../ubuntu-trusty-14.04-armhf.com-20140603.tar.xz
展開に成功すると以下のようなディレクトリができます。
bin boot dev etc home lib media mnt opt proc root run sbin srv sys tmp usr var
Zybo上でUbuntuを起動するために、SDカード(microSD)にパーティションを作成します。
使用するSDカードは8GB以上をおすすめします。
UbuntuマシンにSDカードを挿入したあと、lsblkでマウント状況を確認しましょう。
以下の場合では/dev/sdcとしてマウントされています。
$ lsblk

fdiskコマンドでパーティションを作成します。SDカードのパーティションが何もないところから始めてください。
まず、第1パーティションを作成します。このパーティションはブートローダやLinuxカーネルが入ります。

SDカードにシステムに必要なファイルをコピーします。
コピーするファイルは以下のものです。（SDカードをマウントしてください。）
- ZYBO_ROOT
- BOOT.bin
- devicetree.dtb
- uEnv.txt
- uImage
- ROOT_FS
- Ubuntuのファイルシステム
ZYBO_ROOT
$ cd ~/work_dir
$ cp BOOT.bin /media/user_name/ZYBO_BOOT/.
$ cp devicetree.dtb /media/user_name/ZYBO_BOOT/.
$ cp uEnv.txt /media/user_name/ZYBO_BOOT/.
$ cp uImage /media/user_name/ZYBO_BOOT/.
$ ls /media/user_name/ZYBO_BOOT/
BOOT.bin devicetree.dtb uEnv.txt uImage
ROOT_FS
$ cd ~/work_dir/ubuntu_rootfs
$ sudo cp -rf * /media/user_name/ROOT_FS/.
書き込みが完了したら、Zyboにシリアル接続時、ログインできるようにするため、設定ファイルを作成します。
$ cd /media/user_name/ROOT_FS/etc/init
$ sudo touch ttyPS0.conf
ファイルの中身は以下のようにしてください。
# ttyPS0 - getty
#
# This service maintains a getty on ttyPS0 from the point the system is
# started until it is shut down again.
start on stopped rc RUNLEVEL=[2345] and (
not-container or
container CONTAINER=lxc or
container CONTAINER=lxc-libvirt)
stop on runlevel [!2345]
respawn
exec /sbin/getty -8 -a root 115200 ttyPS0
これでSDへの書き込みは完了です。
Zyboと母艦PCをUSBケーブルで接続してください。
Windowsマシンにおいては、デバイスドライバがインストールされているならば、Tera Termなどでシリアル接続が可能です。
