Hi, I’ve been reading this thread enable watchdog at boot - Toradex Community thoroughly in order to find out how to disable the watchdog. However, @stefan.tx states that is not possible. Uboot does activate PD bit in order to not activate the watchdog after boot has finishes, and then services it using a kernel level timer which any user space application can use.
This is just a confirmation that it cannot be deactivated. Also, if the Tegra watchdog can be used the same way as the VFXX one. I’m not completely sure if both drivers are the same.
