Thank you for contacting NXP Support!

Could you please help me with your information about processor and BSP version?
Additionally, are you trying any guides or manuals as reference to use the watchdog?

I am using the S32G platform, I have used several BSP versions to try such as BSP34, in the kernel according to the above operation watchdog is normal, in the uboot watchdog did not reset the system?

Hi @shiyiheng,

Have you tried any modifications on Uboot build process?
It seems that the watchdog requires a specific configuration on Uboot to enable and set the time. This configuration should be enabled by default on that BSP version; however, I'm still working with the team to confirm that.
