Dear team,

 

I would like to ask about the behavior of i.MX6D PMIC_STBY_REQ.

My customer is trying to add external WatchDog for the workaround of ERR006282.

They tested whether the watchdog can work fine in the case of boot failure by forced removing input to the WD.

And they saw some i.MX6 chips did output High from PMIC_STBY_REQ when POR = L, and some chips did not.

They expected i.MX6 does not output High from PMIC_STBY_REQ when POR gets asserted.

Is the behavior of PMIC_STBY_REQ reasonable?

Are there any ways to make i.MX6 not output High from PMIC_STBY_REQ at POR=L?

 

BTW, the customer uses MCIMX6D7CVT08AC.

 

Thanks,

Miyamoto
