オクタコアのCB4を購入

micro SD にイメージ展開

$ 7za e  linaro-desktop-cb4-card-hdmi-v0.4.img.7z

# dd if=./linaro-desktop-cb4-card-hdmi-v0.4.img of=/dev/sde

差し込んでブート

ペンギン８匹！

rootパスワードとsshdの設定はいつもどおりにツーツーにしておき、ネットワーク設定、ロケール（/etc/default/locale）をja_JP.UTF-8に変更しておく

このイメージは Ubuntu 14.04 trusty ベース

なんかこれまでの、RasPi、CB2、CB3 よりも全然速い気がする。ちょっとベンチしてみたい。

HDMI出力からGUIがあがってくる。

セットアップは Fedora 19 のときとおなじ。

https://dl.fedoraproject.org/pub/fedora/linux/releases/20/Images/armhfp/

初期起動の際に、停止してしまったので、手動で再起動してから、初期セットアップ画面をすませる。

HDMI から VGA へ

SELinux や firewalld とめた後は出力を HDMI から VGA へ（fedora 20 イメージのREADMEに記載あり）

/boot/uEnv.txt  を編集

■変更前

loglevel=5
root=/dev/mmcblk0p3 ro rootwait rootfstype=ext4
extraargs=console=ttyS0,115200 disp.screen0_output_mode=EDID:1280x720p60 hdmi.audio=EDID:0 sunxi_g2d_mem_reserve=0 sunxi_ve_mem_reserve=0 sunxi_fb_mem_reserve=20 sunxi_no_mali_mem_reserve

■変更後

console=tty0
loglevel=5
root=/dev/mmcblk0p3 ro rootwait rootfstype=ext4
extraargs=console=ttyS0,115200 disp.screen0_output_type=4 disp.screen0_output_mode=1920x1080 sunxi_g2d_mem_reserve=0 sunxi_ve_mem_reserve=0 sunxi_fb_mem_reserve=20 sunxi_no_mali_mem_reserve

これでVGAから画面が出る

/ の拡張

「/」のあまりが非常に少ないそのため、以下を実施

• 一度「/」データを別のLinuxマシンに退避
• 「/」の部分をパーティション切りなおし（fdisk）
• ファイルシステム再構築、データの戻し
• fstab は uuid 指定になっているのでデバイス指定に変更（例：/dev/mmcblk0p3  / ext4    defaults,noatime 0 0）
• cubieboard2 へ SD 挿入し起動

fstab を変更せずに起動すると、uuid 相違のせいで read only でマウントされ何もできない

uuid 指定でもいい、以下のようにわかる

[tk@cubie2 ~]$ cd /dev/disk/by-uuid/
[tk@cubie2 by-uuid]$ ls
002f517d-f711-4b81-a4e7-23462f9f3eba 30A1-07B2 57f8f4bc-abf4-655f-bf67-946fc0f9f25b 85943324-a3c5-424d-8410-051fca5f0e92

とりあえずFedora-19でインストール

http://dl.cubieboard.org/software/a20-cubietruck/fedora/
１、別PCにSDカード挿入
２、マウントされてしまってたら、アンマウント
３、イメージの書き込み

[root@sarah CubieTruck]# xzcat Fedora-19-a10-armhfp-r3.img.xz > /dev/sde
[root@sarah CubieTruck]# sync

４、SDカード、抜き差し

[root@sarah CubieTruck]# df

[root@sarah CubieTruck]#

５、u-boot を「cubietruck」で書き込み

[root@sarah CubieTruck]# /media/uboot/select-board.sh cubietruck
Are you sure you want to install the spl, u-boot and kernel for cubietruck from /media/uboot/boards onto /dev/sde ?

６、SDカードを cubietruck にいれてブート（cubieboard1,2のときと違い、解像度が1920×1080に合わせられてる）
７、ロケーション、ネットワーク設定、root パスワード等設定
８、reboot
９、Firewall無効化

# systemctl disable firewalld
# systemctl stop firewalld

１０、SELinux 無効化
１１、yum update
１２、reboot

新しいのが出たので入れなおし。

Cubieboard2 はHDMIが標準なので、拡張ボードを追加して、VGA出力を試みる。

くっつけるのはこんな感じ。

くっつけただけではだめで、ツールを使ってコンフィグする。

• https://github.com/cubieplayer/Cubian/wiki/VGA-output
• http://wiki.androciti.com/index.php?Cubieboard2

要はブート時に読み込むファイルの編集。

1. Sunxi-tools入れる
2. ツールをmakeする
3. uSDのブート領域マウント
4. script.binをローカルコピー
5. 編集
6. script.binをuSDのブート領域へ戻す
7. uSDのブート領域アンマウント
8. reboot

映りました。

解像度上げてみたら、あがらなくなった、「720p50　1024*768」がベストの模様。

あがらなくなったら、uSD抜いて、他のLinuxで再度編集して元に戻すか、バックアップファイルを戻す。

いまさらだが、Cubieboard2 買ったときの値段を書き忘れた。

もろもろで「$90」くらい

1x A simple case for $3.95 each
1x cubieboard2 for $59.00 each

Subtotal  : $62.95 USD
Shipping  : $25.00 USD
Total     : $87.95 USD

ドキュメントを見ればわかることだが、Cubieboardにはフラッシュメモリ（NAND）ものっておりそこにはデフォでAndroidが存在する。ここはそのまま使いたいのでOSを別途入れる時には常にmicroSDに入れてつかうようにする。 NAND Flash 用のイメージも存在するのでそれを使って上書きすることも可能。 しかし、ブートOSを切り替えて遊ぶにはmicroSD試した方が何かと都合がよさそうだし。 今回は、「Cubieez 0.1 RC2 (A20 version)」を入れてみる。

Cubieboard に差し込んで、boot   Terminal を起動して、rootで# cubie-configを実行（デスクトップのREADMEに最初の起動時にそうしろと書いてある）

ファイルシステムを拡張したり、ロケール、タイムゾーン、SSHを起動させたり、選択していじればわかる。 キーボードレイアウトは合ってないので、ここで合わす。モデルはわからないのだが、HP社のを使っているので「Hewlett-Packard Internet Keyboard」を選んでおき、レイアウトに「Japanese-Japanese（OADG 109A）」を選び後はデフォルトにしておく。 完了したら「Finish」して再起動

ベンチマーク

デスクトップのREADMEをみると/rootにベンチマークや、Mali400ソースやらがおいてあるらしい。見てみると確かに。 「tinymembench」というベンチマークが置いてあったので早速実行。

==========================================================================
== Memory latency test ==
== ==
== Average time is measured for random memory accesses in the buffers ==
== of different sizes. The larger is the buffer, the more significant ==
== are relative contributions of TLB, L1/L2 cache misses and SDRAM ==
== accesses. For extremely large buffer sizes we are expecting to see ==
== page table walk with several requests to SDRAM for almost every ==
== memory access (though 64MiB is not nearly large enough to experience ==
== this effect to its fullest). ==
== ==
== Note 1: All the numbers are representing extra time, which needs to ==
== be added to L1 cache latency. The cycle timings for L1 cache ==
== latency can be usually found in the processor documentation. ==
== Note 2: Dual random read means that we are simultaneously performing ==
== two independent memory accesses at a time. In the case if ==
== the memory subsystem can't handle multiple outstanding ==
== requests, dual random read has the same timings as two ==
== single reads performed one after another. ==
