Hi everyone,
The board that I design has not the PMIC for iMX6.
So, I will configure as follows.
12V@3A ---> 5V@3A(DCDC) ---> 3.0V@300mA(LDO) - VSNVS_IN & VDDHIGH_IN (1)
| ---> 1.375V@2.5A(DCDC)- ARM_IN (2)
| ---> 1.375V@2.5A(DCDC)- VDDSOC_IN (2)
|
|
|---> 5V@3A(DCDC) ---> 1.5V@1.5A(DCDC)- DDR3 (3)
---> 3.3V@1.5A(DCDC)- IOs (4)
"(x)" is a power sequence.
Powers will be controlled as follows
(1)powergood => (2)enable => (2)powergood(or voltage supervisor ic) => POR & (3)enable => (3)powergood => (4)enable.
Is this power configuration OK?
Thanks.

Hi chilwonna
I think power up sequence is good. POR should be asserted from
beginning and deasserted when all power supplies and 24MHz/32.768KHz
clocks become stable.

Hi,
Recently I was working on i.MX6 DL sabreSD board without PMIC.
For software issue, What configuration did you modified?
Did I need to modify some driver myself or I just need to set all the configuration which related with Power Management to disabled?
Thanks in advanced!
