После обзора Wandboard Dual в феврале, была получена плата разработки Wandboard Quad на базе процессора Freescale i.MX6 Quad Cortex A9 с 2 ГБ ОЗУ, выходом HDMI, гигабитным Ethernet и SATA. Плата доступна у нескольких дистрибьюторов, включая Mouser ($139), DigiKey ($144.38) и FutureElectronics ($125). Сначала будут показаны фотографии распаковки платы, а также сравнение Wandboard Dual и Quad. Затем будет объяснена установка Android и Linux на плату, сборка образов из исходного кода, запуск тестов производительности и проверка различных функций.
Распаковка Wandboard Quad
Плата была получена через UPS в крупной коробке, содержащей упаковку, показанную ниже. Она идентична Wandboard Dual, за исключением наклейки.
Внутри упаковки находится только плата, которая выглядела бы как Wandboard Dual со всеми разъемами на верхней стороне и модулем EDM на задней панели, если бы не массивный радиатор для охлаждения i.MX 6Quad. Еще одно ключевое отличие — установленный разъем SATA для подключения жесткого диска. Поскольку бумажная документация отсутствует, рекомендуется скачать и изучить руководство пользователя и схемы Wandboard Quad в PDF для получения деталей.
Были сделаны сравнительные фотографии Wandboard Quad и Wandboard Dual. Как и ожидалось, базовые платы практически идентичны.
Старая ревизия платы (A0) заменена на ревизию B1, в которой исправлена разводка SPDIF, обновлено напряжение MIPI, незначительно изменена схема USB и добавлена дополнительная контактная площадка для работы с разными каналами I2C для аудио/HDMI. Еще одно отличие — предохранитель теперь легко заменяется без пайки. Предположительно, все новые Wandboard Solo/Dual/Quad поставляются с Rev B1. Для старых ревизий существует аппаратное исправление для SPDIF .
После снятия радиатора и извлечения модуля EDM из базовой платы видно, что различия между dual и quad модулями минимальны.
На обратной стороне модуля ключевые отличия в чипах памяти: Hynix H5TQ4G63MFR (4 Гбит) на версии quad и Hynix H5TQ2G63BFR (2 Гбит) на версии dual. Отдельно стоит отметить: модули EDM можно приобрести отдельно. Упомянутые в начале дистрибьюторы продают их упаковками по 10 штук.Также был протестирован корпус и антенна Wi-Fi от Wandboard Dual. Сборка не вызывает проблем, несмотря на дополнительный радиатор. Кабель антенны касается радиатора, но это не является проблемой благодаря изоляции.
Установка Android 4.2.2 на Wandboard Quad
Подготовка microSD карты с последним образом Android 4.2.2. Для оптимальной производительности рекомендуется использовать карту Class 10 (в тестах использовалась ADATA 16GB Class 10 micro SD ).
Процесс установки идентичен Wandboard Dual, за исключением образа. Скачивание и распаковка файла:
wget http://www.wandboard.org/images/downloads/android-4.2.2-wand-quad-20130621.zip
unzip android-4.2.2-wand-quad-20130621.zip
Архив содержит 4 файла: образ, краткий список изменений, win32diskimager и «Source_and_Build_Simple_Howtos.txt» — инструкцию по сборке Android из исходного кода, установке Google Play и записи образа на SD-карту.
Вставьте microSD карту в ПК под Linux (8 ГБ или более), размонтируйте раздел и запишите образ:
sudo umount /dev/sdc*
sudo dd if=/dev/zero of=/dev/sdc
sudo dd if=android-4.2.2-wand-quad-20130621.img of=/dev/sdc bs=1M
syncВторая команда опциональна, но необходима, если Ubuntu автоматически перемонтирует разделы (в этом случае dd завершится ошибкой). Выполните «sudo dd if=/dev/zero…» на несколько секунд и нажмите Ctrl+C.
Для установки Google Play выполните дополнительные шаги. Извлеките и повторно вставьте карту, скачайте и распакуйте gapps-jb-20130301-signed.zip , скопируйте Google Play на карту:
cd ~/
mkdir gapps-jb
cd gapps-jb
unzip gapps-jb-20130301-signed.zip
sudo cp ~/gapps-jb/system/* /media/system/ -rf
syncПользователи Windows могут использовать Win32DiskImager для записи образа и adb.exe для передачи Google Play. Однако настоятельно рекомендуется использовать Linux (в дуал-буте или виртуальной машине, например Virtual Box).
Сборка образа Android 4.2.2 из исходного кода для Wandboard Quad
Следующие шаги указаны в инструкции (не тестировались лично):
cd ~
mkdir -p wandboard/myandroid
cd wandboard/myandroid
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ./repo
chmod a+x ./repo
./repo init -u git://www.wandboard.org/android/manifest.git -m default.xml
./repo sync -j4Скопируйте gapps-jb-20130301-signed.zip в ~/wandboard/Build и запустите сборку:
source build/envsetup.sh
lunch wandboard-userdebugПроцесс lunch займет время. После завершения подготовьте SD-карту с правильными разделами:
cd ~/wandboard/myandroid/device/fsl/common/tools/
sudo ./fsl-sdcard-partition.sh /dev/sdXи скопируйте бинарные файлы:
chmod 6755 ~/wandboard/myandroid/out/target/product/wandboard/system/xbin/su
sudo umount /dev/sdX*
sudo dd if=~/wandboard/myandroid/out/target/product/wandboard/u-boot-6quad.bin of=/dev/sdX bs=1K seek=1 skip=1
sudo dd if=~/wandboard/myandroid/out/target/product/wandboard/boot.img of=/dev/sdX1
sudo dd if=~/wandboard/myandroid/out/target/product/wandboard/recover.img of=/dev/sdX2
sudo mount -t ext4 /dev/sdX5 /mnt
sudo cp -a ~/wandboard/myandroid/out/target/product/wandboard/system/* /mnt/
sudo unzip ~/wandboard/gapps-jb-20130301-signed.zip -d /tmp/
sudo cp -a /tmp/system/* /mnt/
sudo sync
sudo umount /dev/sdXОбраз Android 4.2.2 для Wandboard Quad собран и установлен из исходного кода.
Android 4.2.2 на Wandboard Quad: тесты Antutu & Quadrant
Вставьте microSD в слот модуля EDM (под радиатором), подключите HDMI, Ethernet, нуль-модемный кабель, устройство ввода (на фото — приемник Mele F10) и блок питания. Наиболее очевидное положение — размещение радиатора на столе для доступа к разъемам, как показано ниже.
Такое положение препятствует отводу тепла, что приводит к перегреву и зависанию. Радиатор должен быть направлен вверх. В этой конфигурации измеренная температура составила 52°C в режиме простоя и 56°C при выполнении тестов (замеры проводились ИК-термометром ).
При отсутствии DB9 порта на ПК потребуется конвертер RS232 в USB для доступа к последовательной консоли через Putty или Minicom. Пример журнала загрузки для Wandboard Quad:

root@android:/ #Как и на Wandboard Dual, Android работает плавно при использовании быстрой SD-карты. Система стабильна, но требует доработки для полной функциональности. Обнаружены следующие проблемы:
- Отсутствие HDMI-аудио
- Bluetooth включается, но не обнаруживает смартфон; система несовместима с Sixaxis (для подключения контроллеров PS3)
- Аппаратное декодирование видео не работает (как минимум для H.264 и MPEG2)
Однако тесты Antutu и Quadrant показывают значительный прогресс по сравнению с другими решениями на i.MX6 Quad / Android 4.0, тестировавшимися ранее.
В тестах Wandboard Quad сопоставим с Google Nexus 7 на Tegra 3. Примечательна высокая производительность 3D-графики, в отличие от низких показателей мини-ПК Hi802/GK802 при прошлом тестировании, что указывает на существенные улучшения в ПО (Android 4.0 vs 4.2) и драйверах Vivante. Таблица ниже демонстрирует разницу в производительности между Wandboard Dual/Android 4.1.2, Hi802/Android 4.0.4 и Wandboard Quad/Android 4.2.2.

Тест Quadrant показывает, что Wandboard Quad (3402) немного уступает Transformer Prime из-за результатов процессора. Wandboard Dual набрал 2305 баллов.
Учитывая хорошие результаты GPU, была протестирована требовательная 3D-игра: Real Racing 3. Игра работает плавно, с визуально лучшим качеством, чем на платформах RK3188, хотя детальный анализ выявил использование пониженных настроек графики. Тем не менее, 3D-производительность значительно улучшилась по сравнению с ранними версиями i.MX6 Quad на Android 4.0.4.
Сборка Linux через Yocto Project для Wandboard Quad
Доступные дистрибутивы Linux для Wandboard (Quad): Ubuntu 11.10, Ubuntu 12.04, образы на базе Yocto Project или buildroot, Timesys Linux (поддержка Wandboard Quad в разработке) и недавно появившийся образ XBMC Linux . Платы Wandboard поддерживаются в mainline U-boot и будут частично совместимы с Linux 3.12 .
Поскольку установка Ubuntu 11.10 и сборка ядра из SDK для Wandboard Dual уже рассматривались ранее , а использование Ubuntu 11.10/12.04 на Wandboard Quad аналогично (с другим образом), далее будет описан процесс сборки через Yocto Project, позволяющий создавать кастомизированные образы. Инструкции основаны на материалах с elinux.org .
Установка инструмента repo:
mkdir ~/bin
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
chmod a+x ~/bin/repoДобавление в PATH и загрузка исходного кода из Freescale Yocto BSP (github):
PATH=${PATH}:~/bin
mkdir fsl-community-bsp
cd fsl-community-bsp
repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b master
repo syncИспользуется ветка разработки (master), так как Wandboard Quad не поддерживался в релизе Yocto 1.4 (dylan) .
Установка целевой платы Wandboard Quad, настройка окружения и запуск сборки минимального образа:
MACHINE=wandboard-quad
. ./setup-environment build
bitbake core-image-minimalПоскольку все исходные коды скачиваются из интернета и собираются с нуля (включая инструментарий), процесс может занять значительное время в зависимости от скорости интернета и производительности системы. На тестовой машине (AMD FX8350, 16 ГБ ОЗУ) полная сборка заняла три часа. Последующие сборки выполняются быстрее.
После завершения сборки образ будет находиться в ./tmp/deploy/images/core-image-minimal-wandboard-quad.sdcard (28 МБ). Запись на microSD карту (32 МБ или более):
sudo umount /dev/sdX*
sudo dd.sh if=./tmp/deploy/images/core-image-minimal-wandboard-quad.sdcard of=/dev/sdX
syncЗамените /dev/sdX на актуальное имя устройства SD-карты (например, /dev/sdc). Перед выполнением dd рекомендуется проверить устройство командой lsblk во избежание потери данных. После записи рекомендуется расширить раздел rootfs для полного использования объема карты (например, через gparted).
Вставьте карту в Wandboard Quad, запустите плату и получите доступ к терминалу через HDMI-монитор или последовательную консоль:

Poky Next (Yocto Project Reference Distro) 1.4+snapshot-20130725 wandboard-quad0
wandboard-quad login:Для получения образа с графической средой выполните bitbake core-image-sato (см. скриншот интерфейса SATO ). Теоретически, возможна сборка кастомного образа с XFCE путем добавления sources/meta-openembedded/meta-xfce в список слоев и packagegroup-xfce-base, packagegroup-xfce-extended и packagegroup-xfce-multimedia в группы пакетов (через командную строку или графический интерфейс Yocto hob). Однако при попытке сборки XFCE образа для Wandboard Dual через hob ранее возникали ошибки. Предположительно, предварительно собранный образ Yocto для Wandboard Quad включает XFCE (требует подтверждения).
