Watchdog timer doesn't reset IMX8X

We are testing a design based around the IMX8X colibri board. We have however noticed that ones the system crashes the watchdog timer doesn’t trigger a reboot.

The watchdog timer should be enable they are also under /dev/watchdog yet the system does not restart till we reset it by ourselves. This is happening during EMC tests we expect that the USB is causing the crashing of the system.

Dear @davygillebert ,

Thank you for writing to our community!

Are we sure that the watchdog timer is enabled? You could check that (when you are using systems) as told in the following link: http://0pointer.de/blog/projects/watchdog.html
