If counter device supports using zero latency interrupts (ZLI) then expiration callback can be called from that context. This watchdog can be used along hardware watchdog to overcome hardware watchdog limitations, e.g. Nordic devices reset unconditionally at fixed time after hitting watchdog interrupt, leaving no time to print debug information. Watchdog has limitations since it cannot interrupt same or higher priorities so it cannot fully replace hardware based watchdog. if WDT_COUNTER config WDT_COUNTER_CH_COUNT int "Maximum number of supported channel" default 4 range 1 255 help Note that actual channel count will be limited to number of channels supported by the counter device which is used for watchdog. endif # WDT_COUNTER source "drivers/watchdog/Kconfig.stm32" source "drivers/watchdog/Kconfig.cmsdk_apb" source "drivers/watchdog/Kconfig.sam" source "drivers/watchdog/Kconfig.esp32" source "drivers/watchdog/Kconfig.sam0" source "drivers/watchdog/Kconfig.nrfx" source "drivers/watchdog/Kconfig.mcux" source "drivers/watchdog/Kconfig.mcux_imx" source "drivers/watchdog/Kconfig.xec" source "drivers/watchdog/Kconfig.gecko" source "drivers/watchdog/Kconfig.sifive" source "drivers/watchdog/Kconfig.npcx" source "drivers/watchdog/Kconfig.cc32xx" source "drivers/watchdog/Kconfig.it8xxx2" endif
