AM4376: WDT0

Hello Kanae

Thank you for the query.

Please refer to the data sheet.

– One Public Watchdog Timer

– One Secure Watchdog Timer (Avaliable Only on AM437xHS Devices)

In the TRM i am able to find information on watchdog1. 

I assume this is the public watchdog.

Please elaborate your question,

Regards,

Hi Sreenivasa,

Thank you for your reply.

As per my first post, the Datasheet says WDTx1, whereas the keywords WDT0/WTD1 are present in the TRM, which leads me to this question.

From your comment, since WDT0 does not exist in AM437x (public watchdog),
does it mean that we can ignore the "WTD0" keyword in TRM if we only consider the WDT1 setting?
My customer is concerned about the impact of WDT0.

Best Regards,
Kanae

Hi Sreenivasa,

My apologies. I was misunderstanding.
I had thought there was only one WDT when I saw the Functional Block Diagram in Figure 1-1 of the datasheet.

As you posted, I understand that there is only WDT1 except for HS Device.
- One Public Watchdog Timer
- One Secure Watchdog Timer (Avaliable Only on AM437xHS Devices)

Is my understanding correct that if the customer is not using a HS Device,
WDT0 in the TRM is invalid and does not need to be taken into account?

I would appreciate your confirmation.

Best Regards,
