!!!HELP!!!HELP!!! В чем глюк порта uCOS2 под MSP430 при использовании OSIntExit? если заменяю вызовы OSIntEnter/OSIntExit на OSIntNesting++/OSIntNesting-- ВСЕ РАБОТАЕТ ИДЕАЛЬНО! Соблюдаю все правила создания обработчика прерывания по доке uCOS, в отладчике прошелся - при переключении контекстов с момента прерывания и до выхода в прерваную задачу стек в норме ничего лишнего/недостающего не наблюдается, однако ЧЕРЕЗ НЕКОТОРОЕ СЛУЧАЙНОЕ ВРЕМЯ РАБОТЫ (от3сек до 3 МИНУТ, а прерывания идут каждую сеукунду) ПРОИСХОДИТ ЗАВИСАНИЕ ИЛИ СБРОС! при зависании видно что было переполнение стека или LPM0 (в TaskIdleHook) при запрещенных прерываниях... если убрать LPM0 из IdleHook'а, то стабильно сбрасывается еще быстрее... подробности внутри

PORT: TI-MSP430-FOR-uCOS-II-V252.ZIP

задача - по прерыванию освободить семафор, освобождения которого ждет
задача с 0 приоритетом.
Цель пошустрее обработать событие прерывания в subj задаче...
