Hello,

In TDA4vM EVM, PMIC watchdog trig is not used, is it the question-answer Mode?

Thank you!

Hi,

Could you please help clarify your question? Are you looking for a mechanism on how to enable PMIC watchdog? Which PMIC are you specifically referring to? The TDA4x EVM has had an update in the PMIC in a new revision. Which revision of the EVM do you have?

Thanks and Regards

Hello,

TDA4vM EVM version is PROC078E7(PROC078 001 J721EXSOMG01EVM ).

On page 22, the GPIO2 and GPIO11 of TPS659413 are not used as watchdog trig.

There are two modes mentioned inTPS65941x datasheet: "Watchdog Trigger Mode" and "Watchdog question-answer Mode".

Which Mode is used in this EVM?

Thank you！

Hi,

The GPIO11 is used as an NRSTOUT_SOC.

I am checking with the team internally with respect to what the mode of GPIO2 is set to. Based on the schematic the GPIO2 is connected to MCU_I2C0_SDA which strongly suggests that the mode is "Watchdog question-answer Mode".

Thanks and Regards

I confirmed the default is for "Watchdog question-answer Mode".
