Накопились претензии к степени автоматизации работы с ПНП.
Во-первых, ПЛИС'овская часть Zynq'а шьется через процессор командой типа:
cat /tmp/somz.bit > /dev/xdevcfg
Что приходится исполнять после каждой перезагрузки ящика.
Во-вторых, хотелось бы, чтобы ПНП сразу мог начать работать после подачи питания.
В-третьих, на приемной стороне приходится вручную запускать srns_parse_all, tail и матлабовские скрипты.
Автоматическая прошивка ПЛИС
На ум приходит два способа автоматически прошить ПЛИС при запуске ОС: через cron и через init.d. Т.к. далее воспользуемся init для старта службы receiver, то для единообразия и ПЛИС будем шить так.
В Debian нашего модуля по умолчанию используется второй run-level. Напишем скрипт, который будет выполняться при запуске. Для этого в /etc/init.d создаем файл burnzynq:
#!/bin/bash
### BEGIN INIT INFO
# Provides: burnedzynq
# Required-Start: $local_fs $remote_fs
# Required-Stop: $local_fs $remote_fs
# Should-Start:
# Should-Stop:
# Default-Start: 2
# Default-Stop:
# Short-Description: Load .bit to Zynq
### END INIT INFO
echo Zynq burning...
cat /tmp/somz.bit > /dev/xdevcfg
### BEGIN INIT INFO
# Provides: burnedzynq
# Required-Start: $local_fs $remote_fs
# Required-Stop: $local_fs $remote_fs
# Should-Start:
# Should-Stop:
# Default-Start: 2
# Default-Stop:
# Short-Description: Load .bit to Zynq
### END INIT INFO
echo Zynq burning...
cat /tmp/somz.bit > /dev/xdevcfg
Файл делаем исполняемым:
chmod +x burnzynq
Далее добавляем ссылку на него в /etc/rc2.d специальной командой:
update-rc.d burnzynq defaults
Здесь defaults - воспользоваться Default-Start/Default-Stop.
В результате в /etc/rc2.d получаем файл S01burnzynq -> ../init.d/burnzynq.
Если потребуется обновить ссылки на burnzynq или вообще отказаться от его использования, то выполняем:
update-rc.d burnzynq remove
Выключаем/включаем питание приемника. После загрузки ПЛИС готова к работе.
receiver аки демон
Аналогично пишем скрипт для запуска receiver (слизано со скрипта демона rsync):

Делаем исполняемым:
chmod +x receiver
Создаем конфигурационный файл (пока не используется):
echo '#GNSS Receiver configuration file' > /etc/receiver.conf
Создаем ссылки:
update-rc.d receiver defaults
Выключаем/включаем питание приемника. Убеждаемся, что приемник отсылает пакеты.
Теперь с приемником можно работать как со службой:
Usage: /etc/init.d/receiver {start|stop|reload|force-reload|restart|status}
Например:
root@plda:~# /etc/init.d/receiver status
[ ok ] receiver is running.
[ ok ] receiver is running.
