Watchdog fail to reset nano

Jetson nano sometimes gets stuck at the kernel/OS level. During these instances, the watchdog timer does not respond, as it relies on the processor’s clock. I implemented a watchdog timer but observed that when the Jetson nano hangs or gets stuck due to software issues, it is unable to reset itself. Therefore, the only solution seems to be implementing an independent watchdog timer to reset the hardware in case of such hang issues, could you please clarify whether the jetson nano has hardware circuitry available for an independent window watchdog timer? Or would I need to implement this functionality using an external microcontroller, such as an STM32 or ESP32, to handle resets? I understand that the board uses the tegra X1 SOC chip. Can you confirm whether this chip provides hardware watchdog timer functionality? Additionally, could you verify if this feature is available on the Jetson nano module? If it is available, please provide any relevant documentation or examples to help with implementation, thanks!

attached is my nano module no.

Hi,
There is watchdog timer in Jetson Nano and it is enabled by default. Please refer to the topic to test the functionality:
