Hi,TI's firends

watchdog code only in j721e,we can't find this in j721s2.

I need a watchdog to prevent the code from crashing unexpectedly .

So you can provide the appropriate patch or There are other ways to enable a watchdog-like function.

Thanks

Hi,

The latest SDK doesn't have the support for watchdog.

The watchdog support needs three features to work together. The watchdog driver is already existing which is the same as j721e. However there is the soc specific ESM support and also the evm specific PMIC ESM support that needs to be added. That's still not part of the SDK. Hence the dts doesn't have the watchdog nodes. I do not have the exact date for when this will be added. So closing this thread.

Best Regards,

Keerthy

Hi,

We plan to carry out mass production at the end of this month, and it is still quite risky not to add this function. I want to know if you can provide it to us before the end of the month

Thanks.

PMIC drivers for ESM are not yet available so I highly doubt we can deliver by the end of this month.

Currently see the watchdog mode is SPL, I would like to ask the SBL mode under the watchdog can also be used directly Mody

Or, more simply, how to control the PMIC watchdog directly from MCU1_0

Thanks

Our project needs to be started within 5s, so the SBL we use does not have uboot, so please help deal with this matter

Thanks
