About This Document
Previous Nut/OS releases supported the AVR platform only and application programmers could safely use the watchdog routines offered by the avr-libc runtime. Since the introduction of Ethernut 3 board with an AT91 microcontroller, a portable watchdog API is required to maintain portability of applications.
Version 4.1.5 will provided a first Watchdog API, currently implemented for the ARM7TDMI only.
