    День добрый

    Пытаюсь установить драйверы под TI Linux RT

     

    Получаю ошибку:

    но как модифицировать код драйвера, чтобы он заработал с использованием rtmutexes, я не понял. Прошу оказать посильную помощь.

     

    Спасибо.

     

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