Всем привет. Использую камеру MT9D131 и проц at91sam9g20
сумел поднять под линукс twi и как следствие настроить камеру, получилось завести драйвер atmel-isi. могу получать картинки (raw) в режиме превью
получилось достичь результатов максимум 9-10 FPS.
Научился переключаться в контекст Б, при выключенном Jpeg можем получать картинку(raw) заданного размера (согласно контексту Б)
Но при включение Jpeg сжатия, нет прерывания в isi интерфейсе, и я так понимаю, что не приходят маркеры...
Вопрос: каким образом настроит камеру, чтобы при включении контекста Б можно было получить Jpeg картинку?
Что и как я делаю:Функция, которая прошивает регистры камеры:Код

Вторую неделю пытаюсь настроить, но что-то я упускаю, не могу понять что.
При этом, если считывать статусный регистр Jpeg-а, то длинна данных всегда разная, я так понимаю, это говорит, что джипег всеже включился. Но прерывания так и нету.
