The CC2538 the WDT cannot be stopped once it has been started. The CC2530/1 WDT can be stopped if it is running in timer mode, but it cannot be stopped once it has been started in watchdog mode. Both platforms currently provide "dummy" implementations of `watchdog_stop()`, one does nothing and the other one basically re-maps `_stop()` to `_periodic()`. This was originally done in order to provide implementations for all prototypes declared in `core/dev/watchdog.h`. In hindsight and as per the discussion in #1088, this is bad practice since, if the build succeeds, the caller will expect that the WDT has in fact been stopped, when in reality it has not. Since the feature (stopping the WDT) is unsupported by the hardware, this pull removes those dummy implementations. Thus, we will now be able to reliably detect - at build time - attempts at using this unsupported feature.
The Contiki Operating System
Contiki is an open source operating system that runs on tiny low-power microcontrollers and makes it possible to develop applications that make efficient use of the hardware while providing standardized low-power wireless communication for a range of hardware platforms.
Contiki is used in numerous commercial and non-commercial systems, such as city sound monitoring, street lights, networked electrical power meters, industrial monitoring, radiation monitoring, construction site monitoring, alarm systems, remote house monitoring, and so on.
