Hi,

Is there a way to disable watchdog timer/reset on Jetson TX2? I was debugging the kernel module I have made and if I waited too long (ex. examining stack traces, symbols, registers), TX2 resets and this makes it almost impossible to debug my module. Any help is appreciated!

I tried to disable it by running the following command:

```auto
echo 1 > /sys/kernel/debug/30c0000.watchdog/disable_dbg_reset
echo 1 > /sys/kernel/debug/30c0000.watchdog/disable_por_reset

```

But this throws the following error:

```auto
-bash: echo: write error: Invalid argument

```

Try reference to below to implement user space APP for it.  
Or disable the kernel config to rebuild the kernel.

Thanks

- Can you link to a reference for me to see?

- Completely disabling it makes the debugger not working…

I already removed `CONFIG_WATCHDOG_NOWAYOUT` from my kernel config but the device still resets itself if you sit in the debugger for a long duration…

Write the APP to disable the WDT by IOCTL.

Thanks
