CC2340R5-Q1: Watchdog reset abnormally

CC2340R5-Q1: About watchdog timer behavior

Tool/software:

Hi Team, 

In the Post:CC2340R5-Q1: Watchdog reset abnormally - Bluetooth forum - Bluetooth®︎ - TI E2E support forums

We know that : 

Since the watchdog timer cannot be disabled once enabled, the only way to ensure the watchdog does not reset the device is by reloading the timer. Watchdog clear will not stop the watchdog from resetting, only reloading the timer will allow for this. 

Please help to check if TI will have plan to modify the behavior of watchdog timer of CC2340.

If NO, I will let my other customers know to reference the Post:CC2340R5-Q1: Watchdog reset abnormally - Bluetooth forum - Bluetooth®︎ - TI E2E support forums to handle the watchdog feature.

Besides, in the Post:CC2340R5-Q1: Watchdog reset abnormally - Bluetooth forum - Bluetooth®︎ - TI E2E support forums, 

It said that the reset mode can be set as Watchdog_RESET_OFF. 

But the test result from Mr. March in the post seems not working and system stiil reset.

Please help to check if anything is missing in the following code

 

Thanks.

    Hello Mike, 

    March is using the RESET_OFF, resestMode. Is he resetting the device within the callback function, or is the device still resetting with this resetMode, and no reset within the callback? 

    Additionally, is March attempting to reload the timer still? The two options for resetting the watchdog are reloading the timer before the timer expires, or using Watchdog_RESET_OFF, to enter the callback instead of resetting. Please clarify which one is being used. 

    Thanks, 

    Isaac

    Hi Issac,

    Thanks for the comment. I will contact March to check which option is being used.
