I tried to use the watchdog timer to do a software reset.
wdt_enable(WDTO_2S)
while(1) {};
The reset works fine but after that the board keeps resetting in an infinite loop.
Therefore I disabled the watchdog in the start of the setup() function:
void setup()
{
wdt_disable();
}
This doesn’t help, it keeps resetting which is weird because it has 2 seconds to disable.
Because of the infinite resets, it is difficult to load a new program but not impossible.
How can the watchdog be used?
