Hello,

I was trying to use a watchdog timer on the openmv ae3, but was getting the error below. I’ve linked a similar issue for the OpenMV Cam M7. Is there a way this could be enabled in firmware?

> AttributeError: ‘module’ object has no attribute ‘WDT’

`from machine import WDT`  
`wdt = WDT(timeout=2000) # enable it with a timeout of 2s`  
`wdt.feed()`

As explained to that link : [class WDT – watchdog timer — MicroPython 1.15 documentation](http://docs.openmv.io/library/machine.WDT.html) I wrote that code : import machine watchdog = machine.WDT(timeout=1000) while(True): watchdog.feed() But when I run the script I get this error : AttributeError: ‘module’ object has no attribute ‘WDT’ Do somebody know how to use correctly the watchdog timer ?

There’s no watchdog support yet. This is a to-do list item from Damien. [OpenMV Features · GitHub](https://github.com/orgs/micropython/projects/5?pane=issue&itemId=167690108&issue=micropython%7Cmicropython%7C18961)
