The forests each have a fuelwood permit system that allows members of the community to lawfully cut a designated number of cords of firewood each year. The investigation later expanded to include the Nez Perce and Boise National Forests. Through numerous investigative methods, officers learned that Kersten was acting as a “watchdog” for the group and was illegally removing trees and creating unauthorized roads and campsites in the forest. These individuals were cutting and removing timber illegally and then selling it as firewood in the local communities. Forest Service officers received information about a group of individuals who were causing extensive natural resource damage in the Payette National Forest near McCall.

In addition, Kersten was ordered to pay the government $8,000 in restitution and banned from entering all National Forest System lands for a period of three years.Īccording to court records, beginning in late 2018, U.S. (the rest of the operating system could have crashed).BOISE – Richard Russell Kersten, 36, of McCall, Idaho, was sentenced to one month in federal prison for illegally harvesting timber from national forest lands, U.S. Most system ticks are interrupts triggered by a hardware timer, which just proves that the timer is running o.k. Can I Use The System Tick?ĭo not use the system tick to feed the watchdog. If any one task has failed to check in on time, the watchdog task should not feed the watchdog, which should then cause the watchdog to fire. If all tasks have checked in on time, the watchdog task feeds the watchdog. A watchdog task regularly runs and makes sure that every task has checked in within it’s specified time limit. A Better ApproachĮach running task should “check-in” within a certain period of time. Other tasks could be in a “locked” state and the watchdog task would never be the wiser.

However, this only proves that the scheduler is working well enough to call this one task at the correct time.

A Simple ApproachĪ simple approach to implementing a watchdog in a multi-tasked FreeRTOS application is to create a new watchdog task whose responsibility is to feed the watchdog at a constant rate. The multi-tasked nature of FreeRTOS presents challenges when implementing a watchdog.
