Hi
I am designing a system with i.MX6 Solo processor with MMPF0200.
My system needs the Processor to turn ON automatically when the power is applied ( No Button press).
In below community, if we need to turn ON automatically, we should control the POR_B.

So, I thought the attached circuit.
Is it correct?
If the circuit is correct, what is the recommend connections of PMIC_ON_REQ ?
Please clarify,
Sincerely

Hi ko-hey
I think it is correct, also would recommend to connect
PMIC RESETBMCU to processor POR as done in Sabre SD
schematic. PMIC_ON_REQ may be left unconnected.

Hello Shichin Huang,
Did you find by any chance a way to get rid of the "power on" button?
We're facing the same issue and we'd appreciate if you could share a solution to that.

Hi igor,
But if disconnect PMIC_ON_REQ signal from i.MX6 to PMIC,
you cannot power off PMIC power when you normally shut down from OS.(ex: press power off icon of Linux.)
Do you have any idea about auto power on and also support PMIC off when system normally shut down from Linux?
Thanks!

Shichin
