watchdog over time , can not restart

[Ben_iot]

hello :

  We have a device that is ble master-slave and includes OTA function.

  1. When the device adds a watchdog, the watchdog callback is triggered (wdt_event_handler), but the device does not restart, the program does not run, and it does not enter the bootloader

  2. When the device does not add the watchdog and burn the bootloader, the watchdog Timeout can restart the device

  Probably what caused this imagination, insufficient RAM?

It's not obvious if you start the watchdog in the bootloader or application code here, or both?

Is there a difference if debugger is connected or not?

Is there a difference if pin reset is enabled or not?
