Live Debug don't work, device resets because of watchdog

[tadeubas]

I've tried to follow the steps here to live debug a MaixDock: https://github.com/selfcustody/krux#live-debug-a-device

Win 10 Pro v 21H2 - AMD x64 processor - USB 2.0
MaixPy IDE 0.2.5 (Tools > Open Terminal)
MaixDock M1 (without wireless, encoder KY-040 soldered)

Everything works but after a while Krux resets the device, the image below shows the terminal running, CRTL+C pressed, some arbitrary math executed and suddenly the Krux watchdog restart:

Makes sense. That's unfortunately the watchdog working as designed. This can be worked around by increasing the RESET_TIMEOUT value in src/wdt.py during development and testing: https://github.com/selfcustody/krux/blob/main/src/krux/wdt.py#L24

If this isn't sufficient, there may be a way to modify maixpy_main.c in the MaixPy repo to disable the watchdog on interrupt.

Yes I have disabled it! You just need to add this line on the src/wdt.py:

wdt.stop()

The only problem is that you need to compile the code and flash the device... I will submit a PR complementing this info in README

I've created a way to disable Krux watchdog without the need to build the project from source (see the open PR).

Instructions are presented at README, the user only needs to create a property called WATCHDOG_DISABLE in the config.jsonfile at the device /flash (this is possible to do just before the Krux watchdog resets the device)
