Hello, all.

I have a question about 'RTC external battery' of  'i.MX6 Dual lite'.


I designed circuit about 'RTC external battery' like below. That refer to 'SABRE Bd' circuit.

I confuse about consuming current of 'RTC external battery' is too much. That consumed about 16mA.

I think needed setting register about 'MMPF0100NPAZES(PMIC)'  or 'i.MX6DL' , Is that right?


And, It seems RTC external battery not full charged. Is that needed setting register?


Please, inform me that problems ,ASAP.


Best Regards,
