_FDEV_SETUP_WRITE was not declared in this scope
в инете нашел единственный вариант для SAM
sam printf
Simple print functions for Atmel SAM microcontrollers using DMA
в описании указан "наш чип" как протестированый
собирается без проблем (кроме варнингов, возможно следует присмотреться?!, undefined reference - это не хухры мурхры)
печать не работает (пробовал по разному)
варнинги (пути к тулчейну усечены, для удобства восприятия)

понимаю, что можно взяться разгрызать
- реализацию класса Arduino-Due/Serial.xxx
- реализацию стандартной печати в asf-library
и то и другое, понятное дело, работает, но хотелось-бы пока разобраться с данной библиотекой
как обычно, принимаются любые идеи/ссылки/советы по делу, помидоры в разумных количествах, можно просто побалагуить... но, желательно в тему :о)
!!! ADD !!!
ТЕСТИРОВАЛ ЭТУ И МНОГИЕ ДРУГИЕ ПОДОБНЫЕ БИБИЛИОТЕКИ, НИ ОДНА НЕ РАБОТАЕТ
УТОЧНЯЮ - КОНТРОЛЛЕР SAM3X8E
спасибо
