it's good to track this, but I think @hakehuang we found this before internally, the issue was something to do with the lack of ram retention IIRC, we will have to consider a solution for it. It's not really that there is a bug related to the watchdog, though, so I am wondering if we should track this as a watchdog bug or some kind of enhancement

if we should track this as a watchdog bug or some kind of enhancement

I think the could be an enhabcement.

We have had other platforms that had this same problem with RAM retention and various test cases that assume the platform can retain RAM.
