How to check WDT trigger

I am always grateful for your help.
Regarding the title, can I check in dmesg, /var/log/messages and journalctl -b, etc.?

Usually the reset reason of the module is shown either in U-Boot or Linux Kernel console messages, so user can identify if the SoM was reset by Watchdog or not. Please check this article for details - Watchdog (Linux) | Toradex Developer Center
