I was able to write a small application for triggering the watchdog (from user-space), following one of the examples here in the forum. The board rebooted as expected. I’m going to run some software which could eventually cause the watchdog to trigger if something goes wrong. These software would run for long time, even during night. I’m wondering now if there is a way to know if the board rebooted because of the watchdog, for example reading some registers (or file). What I would like to do would be to run a script at reboot that checks if the last reboot was caused by the watchdog. Do you know if it is possible to do something like this?
