Hi , MartinOur
Watchdog uses two GPIO to control, one is to use pulse to switch the
watchdog, one GPIO is used to feed the dog, specifically the external
single-chip to feed the dog, now the external single-chip cannot detect the
level change of GPIO I now suspect that the wdt-gpio delay is too short, and
the microcontroller part has not detected a falling edge change. I tried both
toggle and level, but unfortunately both failed, and I will continue to test.

Why exactly?

How is it able to detect the level change using another method then,
what exactly makes them different?
