Description

WDT working for the STM32, MIMXRT, and Alif on the machine module.

All watchdog types need to work. For example, on the STM32, only the IWDG is implemented right now; however, this watchdog will reset you during deep sleep. There's another watchdog on the STM32 that turns off when in deep sleep.

No response

Implementation

I hope the MicroPython maintainers or community will implement this feature

Yes, I agree

WDT erroneously enabled ?

When running latest version of micropython (esp32spiram-20191011-v1.11-422-g98c2eabaf.bin) on attached code I get following runtime message:

E (2120640) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time:
E (2120640) task_wdt: - IDLE1 (CPU 1)
E (2120640) task_wdt: Tasks currently running:
E (2120640) task_wdt: CPU 0: IDLE0
E (2120640) task_wdt: CPU 1: mp_task

When running code using micropython (esp32-20190529-v1.11.bin) runtime message does not appear. Is the latest version buggy? Or do I have to feed the watchdog? How?
