How to enable H/W reset when watch dog timer expired

Hello,

About BF70x

I would like to know procedure to enable H/W reset when watch dog timer expired.

I suppose watch dog timer register just only enable to write WDOG_CTL with 0x00000xx0 (xx is any value except 0xAD).

But I suppose also set RCU registers but cannot figure out.

If you have any sample code to enable watch dog timer, I would like to appreciate it.

Thank you for your help as always.

Best regards,

Sofy

    Hello, Jithul-san,

    I would like to confirm about invoking reset by watchdog timer expiration.

    Are both WDT expired and FAULT in SEC required to invoke reset?

    I've trying to test your sample with EZmini but there seems no reset occurred. (with SPI Flash Memory Boot)

    So I suppose both WDT expired and FAULT in SEC are necessary to invoke reset, isn't it?

    If the answer yes, I appreciate if you let me know how to make FAULT on purpose.

    Thank you for your help as always.

    Best regards,

    Sofy
