CONFIG_ESP_TASK_WDT_PANIC
Invoke panic handler on Task Watchdog timeout
Found in: Component config > ESP System Settings > CONFIG_ESP_TASK_WDT
If this option is enabled, the Task Watchdog Timer will be configured to trigger the panic handler when
it times out. This can also be configured at run time (see Task Watchdog Timer API Reference)
Default value:
• No (disabled)
CONFIG_ESP_TASK_WDT_TIMEOUT_S
Task Watchdog timeout period (seconds)
Found in: Component config > ESP System Settings > CONFIG_ESP_TASK_WDT
Timeout period configuration for the Task Watchdog Timer in seconds. This is also configurable at run
time (see Task Watchdog Timer API Reference)

CONFIG_ESP_TASK_WDT_CHECK_IDLE_TASK_CPU0
Watch CPU0 Idle Task
Found in: Component config > ESP System Settings > CONFIG_ESP_TASK_WDT
If this option is enabled, the Task Watchdog Timer will watch the CPU0 Idle Task. Having the Task
Watchdog watch the Idle Task allows for detection of CPU starvation as the Idle Task not being called is
usually a symptom of CPU starvation. Starvation of the Idle Task is detrimental as FreeRTOS household
tasks depend on the Idle Task getting some runtime every now and then.
Default value:
• Yes (enabled)
CONFIG_ESP_TASK_WDT_CHECK_IDLE_TASK_CPU1
Watch CPU1 Idle Task
Found in: Component config > ESP System Settings > CONFIG_ESP_TASK_WDT
If this option is enabled, the Task Wtachdog Timer will wach the CPU1 Idle Task.
Default value:
• Yes (enabled)
CONFIG_ESP_XT_WDT
Initialize XTAL32K watchdog timer on startup
Found in: Component config > ESP System Settings
This watchdog timer can detect oscillation failure of the XTAL32K_CLK. When such a failure is de-
tected the hardware can be set up to automatically switch to BACKUP32K_CLK and generate an inter-
rupt.
