CONFIG_TASK_WDT_MIN_TIMEOUT

Minimum timeout for task watchdog (ms)

Type: int

Help

The task watchdog uses a continuously restarted k_timer as its
backend. This value specifies the minimum timeout in milliseconds
among all task watchdogs used in the application.

If a hardware watchdog is configured as a fallback for the task
watchdog, its timeout is set to this value plus
TASK_WDT_HW_FALLBACK_DELAY.

Direct dependencies
