Hi Volkan,

A trick is to use the IDWG: Activate it and loop forever. Once the timeout expires, a reset is generated.
A drawback of this method is that it is relatively slow.

Here is the code:

    // Reset the CPU: Enable the watchdog and wait until it expires
    IWDG->KR = IWDG_KEY_ENABLE;
    while ( 1 );    // Wait until reset occurs from IWDG

Regards,
Bruno
