EDIT : I've just give this a try, but oooups ! 1 million wasn't enough, 100 million is better.
But beware : I've saw sometimes the watchdog doing reset, but the reset was also hanging sometime.

I tried your "blocking-code":

Code: Select allvoid setup() {
  Serial.begin(115200);
  Serial.println("Programmstart ");
}
void loop() {
  Serial.println("Loop ");
for (int i = 0; i < 100000000; i++) { __asm__ volatile ("nop"); }
}

And there was (now about 1/2 hour) continously a reset:

Code: Select all ets Jan  8 2013,rst cause:4, boot mode:(3,6)

wdt reset
load 0x40100000, len 28780, room 16

You means it took 1/2 to reset ?
From my yesterday's tests, it didn't took even half second ...

No
I let it run over 1/2 hour. And it was resetting the whole time. Again and again. Every ~ 4 seconds.

So, now you can add some randomness in your sketch, so it will reboot only randomly ...
Have fun !
Ciao !
