Watchdog reset reason
How to debug what's behind a system reset because of watchdog? I tried using dynamic debug and add stm32_iwdg.c file to print debug output, but that didn't give me more info, just some pings. So what can be reason for watchdog reset? We have program on A7 which is doing some tasks when it is waked up via virtual uart from Cortex M4 which is running all time. Waking up is going well until one time when system is gone in low power and then it is rebooted and reset reason is 0x214, which is wdg reset. Virtual uart wakeup is enabled all the time. I also tried to disable watchdog in kernel menuconfig, but obviously then same case happened after some time (20minutes, 30minutes...) but there was no reset, because there was no wdg, so wdg is just doing it's job.
Thanks in advance,
