However, if the watch dog timer is ever expired for whatever reasons, the system must reboot back and must not stuck waiting for someone to come and press the HW reset button. No matter what is the reason for wdog reset, at the end of the day its a kind of system Or CPU reset and system must re-start.
Btw thanks for the great chip.

then nothing until reset button pressed.
Any ideas please or is this an SDK bug?
Ok,I think the point is :
If a watchdog reset occurs, the chip would exactly go back to the same mode as the chip was in, when it was powered on last time.
That is , if you set the chip into download mode and download a firmware,then without a rebooting and run the code directly,
in this case, when there was a watchdog reset , the chip would of course go back to download mode.
So please make sure you reboot the chip and run in flash boot mode first.
