Всем добрый день! Пишу приложение на gstreamer. Не могу понять как работает обработчик g_main_loop_run(Mainloop). Он очень схож с gtk основным циклом. Я пытаюсь реализовать проверки времени. Однако после ухода в бесконечный цикл никакие условия не работают. Думаю сдесь нужно через колбэки. Только как это сделать, пож объясните.
Что-то я не понимаю, как его использовать? Я подключил монитор через hdmi, монитор не видит видеосигнал, но видит что кабель подключен. Экран черный.
# cat /sys/class/graphics/fb0/virtual_size
2048,8640
попытка записать туда другое значение безуспешна.
fbi -T 1 img.jpg
тоже не влияет на ситуацию, экран остается черным.
прошито дебианом с ядром 3.10
Выставляю fbset'ом другое разрешение, 1920x1080, ставится, но видеосигнала все равно нет.
mode "1920x1080-61"
# D: 74.250 MHz, H: 33.873 kHz, V: 61.476 Hz
geometry 1920 1080 2048 8640 16
timings 13468 140 88 15 2 44 5
hsync high
vsync high
laced true
rgba 5/11,6/5,5/0,0/0
endmode
Если подключить usb клаву, то можно залогиниться вслепую на tty1. запуская fbi с него тоже ничего.
При это хоть что-то все-таки в монитор идет, т.к. на нем есть индикатор, который мигает, когда монитор подключен к выключенному устройству и горит, когда к включенному. У меня он начинает гореть через некоторое время после включения платы.

Поясните если можно. Кирдык памяти NAND ?

И что делать ?
1) Укажите на инструкцию по установке linux-3.10.x из вашего репозитория https://github.com/RC-MODULE. Какие шаги необходимо проделать, чтобы установить linux-3.10.x?
2) Не планируется ли партировать OpenCV на DSP Neuromtrix, или завести отдельную ветку для этой библиотеки?
3) Где посмотреть примеры обработки цифрового сигнала со спутников, ну и какие OEM-приемники стоит использовать?
4) Будет ли порт под FreeBSD (ARM), если будет то когда?
Спасибо.
Доброго времени суток. Собственно вопрос в следующем можно ли дергать gpio напрямую, минуя sysfs? P.S. если можно, то подскажите как? через nmc пока не предлагать.
Скоро должна прийти долгожданная платка. Хочется интегрировать ее в робота вместо RPi. Робот передает видеопоток на хост. Для RPi это делалось через Raspberry Pi camera module. Возникает вопрос - какую камеру и как прикрутить к MB 77.07 (нужен realtime поток на хост через wi-fi с минимальной задержкой).
