Драйвер NPort для Linux 4.x

Efimov · October 18, 2016

Здравствуйте!

Существует драйвер для 4 ядра?

Alexandra · October 18, 2016

Добрый день!

К сожалению, пока поддерживаемые версии ядра только 3.х. Попробуйте, установить последнюю доступную версию драйвера (во вложении), но не факт, что она заработает на Linux 4.х

ver1.18.51.zip

Efimov · October 21, 2016

Драйвера установились (ОС AstraLinux SE 1.5 ядро 4.2.0-23-generic) и заработали на серверах HP и в виртуалке.

Но есть проблема с серверами DEPO.

Схема такая:

Соединяем два порта NPort перемычкой (P1 <-> P4).

В одном терминале пишем в порт:

echo "123" >> /dev/ttyr00

Проходит нормально, индикаторы на NPort моргают.

В другом терминале читаем из порта:

cat /dev/ttyr03

В итоге cat зависает, а в первом терминале получаем:

Может кто сталкивался с таким?

PS: NPort IA 5450

tpa58 · December 21, 2016

Аналогичная проблема с такими же логами ядра... похоже, зависит от железа. В моем случае успешно работает на чипсете Intel H81 и ловит ошибку на Intel H110. ОС одинаковая - Ubuntu 16.04 64bit. Обновление ядра с 4.4 до 4.9, переход на 32bit, полная замена железа (материнская, память, проц, HDD) не помогает...

Проверено на Nport 5430 и 5110.

Проблема решена! Попробовал драйвер из сообщения по ссылке, в описании версии упоминается ядро 4.4, всё заработало сразу. Еще исправлена автозагрузка при старте ОС.

Драйвер для ядра 4.4

Пытаюсь установить драйверы под TI Linux RT

Спасибо.

В итоге скомпилировать драйвер под arago linux получилось, но при выполнении команды mxaddsvr выводится ошибка:
