In our application we using nrd5340-nrf7002, application flow is wakeup->wifi connect->NTP time get->TCP server connect->wifi shutdown->idle->wakeup.....
We are encountering a "Received watchdog interrupt" issue during run time on four devices after Wi-Fi connects, when SNTP server or DNS resolution fails. When DNS resolution fails, the watchdog triggers, causing the device to freeze and require a hard reset.
We are encountering a "Received watchdog interrupt" issue during run time on four devices after Wi-Fi connects, when SNTP server or DNS resolution fails. When DNS resolution fails, the watchdog triggers, causing the device to freeze and require a hard reset.
Given that our SDK version 2.6.2 does not have any explicitly enabled or configured watchdogs, we suspect a hardware watchdog issue. Since the system isn't automatically recovering, what mitigation strategies and recovery mechanisms do you recommend?
Although infrequent, we want to implement a robust solution for prevention and recovery. Could you provide guidance on potential causes, debugging steps, and recommended mitigations for this issue?
Here I attach the log for your reference.
