framework watchdog

Problem background Since working on stability, I have learned that the framework has a watchdog to monitor whether the main process is stuck. If it is stuck for 60 seconds, the process in which it is located will be killed, which is system_server, and the upper layer will be restarted. Just search for the key […]

GD32F103VE window watchdog timer

GD32F103VE window watchdog timer There are two watchdog timers (WDGT): 1. Independent watchdog timer (FWDGT) 2. Window Watchdog Timer (WWDGT) After the window watchdog timer is turned on, its 7-bit down-counter works. When the count value of “downward decrement counter” reaches “preset window value”, it will command the CPU to reset; In order not to […]

GD32F103VE independent watchdog

GD32F103VE independent watchdog There are two watchdog timers (WDGT): 1, Independent watchdog timer (FWDGT) 2. Window Watchdog Timer (WWDGT) The independent watchdog timer (FWDGT) has an independent clock source (IRC40K). The independent watchdog timer has a down counter, when the counter reaches 0, it will reset the CPU. In order to prevent the independent watchdog […]
