Добрый вечер.
Провел тестирование на отваливание сети. Проблема появляется только с dhcp настройкой сети на wb! Дальше буду еще наблюдать.
отключил питание роутера

далее вывод ifconfig

далее опять рестартим сеть, в логу роутера отображается запрос на адрес

на статике из двух попыток не было проблемы

16

Угу, понятно тогда. Судя по логам, роутер при старте поднимает линк, потом опускает, потом снова поднимает. Бывают такие кривые прошивки.
От этого видимо сходит с ума связка netplugd + udhcpc, причём с большой вероятностью первый. Исправлять - никак. Вот в ubuntu это исправили написанием NetworkManager, но мы его по очевидным причинам перетянуть в Wiren Board не можем.
В общем обходить это нужно статикой, сменой роутера, либо можно попытаться пошаманить со скриптами netplugd. Мы, по крайней мере пока, на это тратить ресурсы не будем, т.к. ситуация редкая.

17

Тогда стоит это пометить в wiki, что бы владельцы роутеров это учитывали.

18

Проверка на влияние Wi-FI прошла успешно – 16 дней аптайма, после ifconfig wlan0 down CLI не отваливается. Пользуюсь проводным интерфейсом. Я не менял настроек Wi-Fi – устройство было сконфигурирован как точка доступа по умолчанию. Как в этом случае можно исправить ситуацию, чтобы Wi-Fi не мешал работе устройства? Про кривые драйверы в курсе.

19

12 дней работает нормально. Изменение на статический адрес помогло!

20

Добрый вечер.
Обновил до последней версии wb-mqtt-homeui, на установке остальных пакетов повисла консоль.
Если пытаться подключиться к WB, то никаких ошибок не выдает, но при этом не подключается.
Подцепился UART кабелем, но там тоже тишина, просто черный экран без сообщений, подключение правильное.
Не успел настроиться вот этот пакет libldap-2.4-2:armel (2.4.31-2+deb7u1), передним была установка tzdata.

21

Перезагрузитесь, сделайте apt-get -f install.

Судя по всему вы делали apt-get upgrade, если у вас стало ставиться много пакетов. Не нужно этого делать без необходимости.

22

да, сделал apt-get upgrade и после повисло.

там еще dpkg надо запустить, чтобы исправить.

23

Очередное зависание, увы:

Может, все-таки что-то не так в моем Wirenboard с аппаратной частью?

24

Я уже писал, дело в потреблении памяти. Выгружайте все сервисы перед обновлениями или запускайте их через chroot.

25

Спасибо, попробую!

26

Спустя пару недель работы доступ к WB пропал.
Достучаться получилось только через консоль, через CTRL+Pause и убив все задачи (i)
Кусок dmesg, после чего доступ пропал

А вы Wi-Fi используете? Похоже на него.

28

использую как доступ в интернет. Адрес статический. При загрузке присутствует deadlock стандартный.

29

У меня аналогичная проблема, после примерно недели работы Wiren Board перестал откликаться и выполнять пользовательские сценарии. Помогла перезагрузка.
Может уже кто дэбажил данную проблему?

30

Расскажите пожалуйста, что за ПО запущено на контроллере? Есть ли возможность подключить USB-UART и посмотреть, что происходит во время или после зависания?

Напоминю, что у нас есть watchdog и его можно сконфигурировать, чтобы он сам перезагружал устройство, если оно перестало что-нибудь делать. Критерии когда именно перезагружать настраиваются.

31

Запущен чистый образ, дополнительно ПО не устанавливал. При следующем зависании попробую подключится по USB-UART.

32

Снова через две недели работы доступ к контролеру пропал. Через UART доступна только диагностика ctrl+Pause.
Подскажите, как настраивать встроенный watchdog?

33

Устройство /dev/watchdog1 .
Можно поставить стандартный демон watchdog из Debian, документацию к нему читать соответственно.

34

После раскатки нового образа 2 раза за 8 часов висло намертво.
Вот dmesg https://dl.dropboxusercontent.com/u/4094156/dmesg.txt
Подскажите чего сделать.
