Hi , Paul
Sorry, I misread the mail contact.
Our 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?
